Have to agree with you there, and it's one job where I wasn't entirely happy with the physical appearance at the end (a rare case where trunking would actually look better). The scope of works was for one-off, one-on, but when the boots were on the ground I made the snap decision to relocate it to make it more accessible. That rather added to the work and the van hadn't been stocked with the necessary materials, but sometimes you make a call on-the-go for what seems the right reason only to stand back at the end and think it would have been better if...
Thanks for a reply David, I thought as much being the ledge that you are and totally agree with your decision to relocate for accessibility. It is in a garage after all and doesn’t need to look like a work of art, unless you’re attracting clients that enjoy staring at brick walls
@@dannyboisparky Well, there's no point only showing the slick jobs that always go according to plan. Does you good to throw onto here an honest account of how the day went sometimes!
Yes trunking would have been much better - and a main isolator fitted. Trunking always makes a job look more professional looking. Customers are impressed. Also a quicker job overall. Just put the cables inside the trunking once the trunking is up with holes drilled in. Trunking could have gone down the right of the meter near the soil stack, then over the top of the CU. Trunking is quick to fit. Trunking looks more professional when you have an angle saw to get the nice snug fit 45 degree cuts.
@@dannyboisparky Surface work should always look good. Personally I would have considered removing the ugly old fashioned wooden board. The cable from the main DNOs mainfuse into trunking above it, with a main isolator and the meter's cables running in and out of trunking not seen, or little of it seen.
Hi David and co. Regarding dual busbar boards, the French have been using them for years. 20 years ago I rewired my house in France and the board had dual busbars and double pole MCBs. The incoming supply had a 100mA RCD included and the board was protected with a 30mA RCD. The village was supplied from a 3 phase supply with the houses supplied from 2 phases giving 230V. This meant that the conductor used as the neutral wasn't really neutral! Single pole switched lights still had dangerous voltages on the "neutral" The village supply has all been changed now to something more sensible! I am a keen DIY / Electrical and Electronic Engineer and think your videos are great. I have learned a lot from guys like you on UA-cam. Keep up the good work, and the banter!!
Yeah, I hear dual busbar is common on the continent so I'm not sure why manufacturers do it differently for the UK. Dual busbar makes a lot more sense to me!
So the wiring there is presumably approaching 60 years of age? Any thoughts on when/if one should recommend a complete re-wire on the basis of future viable lifespan? Or do you feel the IR readings and/or any Earth-leakage tests is sufficient to gauge servicibility?
You have to take each installation on its merits of course and make an engineering determination. In this case, nobody had messed with the wiring since the original build, with the exception of the cooker circuit modified to a socket endpoint by the new owner, so it was all as-built and pretty solid. The endpoints need refreshing; new lights, new socket outlets, but the new owner doesn't have plans to make many modifications outside of the kitchen. We could rip out and start again, but it's good copper, the insulation is bearing out, no major changes are planned, so why go to the expense?
SBS is *two* busbars Line and Neutral. The Continental makes like, LeGrande, Garo and Schneider have _twin_ busbars where the L & N are all in one unit. Schneider call it a comb. Schneider and Garo makes are now on sale in the UK, and about time! The Schneider multi-row CUs are now sold in S'fix, even the DP MCBs.
@@dsesuk Lets be honest the only way to look at any social media is to be under the influence, it's a must for looking at the cesspool that is Twitter 🤣
I’m surprised the influence of Bundy hasn’t extended as far as getting you to use Flexicon to tidy up the cable extensions! Best wishes to Nigel - but Linda was fun 🤩
Some decent trunking would have looked better, but originally it was just supposed to be a like-for-like swap rather than a relocation job. One of those on-the-fly ideas that maybe didn't work out as aesthetically as it could have.
@@dsesuk so why did you not mount the db in place of the old instead of jointing all the cables and also why does the db have to be metal with a plastic adapter box above as a joint.
@@scottsparky1 The whole plastic thing is a nonsense in my opinion Scott, but it only applies to switchgear and even then not to DNO equipment, so the DNO can install an isolator in a plastic box, but if I put one in it's supposed to be metal. My NIC assessor had me on that recently as I'd installed a KMF switch on a domestic property. It was inside the coal hole so not actually inside the property as such, but he did me for it not being metal. I don't know why I decided to make life more difficult by relocating it, I just felt it would be better for it to be more accessible.
On my second SBS board and this one's a biggy with standby generator and 18 circuits, can't fault it, the delivery, service, price and quality are excellent.
i employed a girl 20 years ago after my local college asked me so she could finish her last year at college as i have took foreign exchange students in the past for them , it was horrendous as every job customers / staff just kept talking to her as girls were never seen and innuendos from staff and customers had me petrified of prosecution , she finished her time and left , and my nerves returned to normal and the work returned to its normal pace . now we see lots more females and linda has done a good quality job with you
Sounds like a shit situation all round. Hopefully, the landscape is shifting and people can be appreciated for their skill and knowledge of the job over anything else.
We have had similar single mod rcbo's with a dual bus-bar connection in Ireland for a while but because of the small connections in the bus-bar the biggest cable that fits into the bus-bar is 6mm panel flex with bootlace ferrules so you can only fit a few rcbo's rated at 20 amp or smaller on one dual bus-bar not to overload the 6mm, that does not seem to be a problem with the SBS board the pictures or the SBS board are never clear enough to see how the bus-bar connects to the main switch, they do not sell the single mod rcbo's with the blue neutral lead in Ireland which is a pity they seem a good idea
Maybe I should pull apart the next one to take a closer look at the busbars and main switch arrangement Paul. These are all 100A rated of course. I'll have another one to fit in the coming weeks.
@@dsesuk Thanks for replying so quickly, the main bus-bar in distribution boards over here for mcb's and dual bus-bar for the larger rcbo's are normally rated at 80amps I just had a look in my van to check the size's but there is nothing written on the small dual bus-bar for the single mod rcbo's I guess they are rated less than 80 amp because they look so small but maybe I'm wrong as usual I will have to find out what they are rated at but as I said above 6mm cable is the largest feed you can connect, so long as they are rated at 40 amp or larger that's OK in Ireland.
Any good reason for putting the garage on a B16 rather than a B20? I feel you missed a trick with moving the board; when I'm doing that sort of upgrade I get it mounted, connect up all the extension pieces and get as much as possible sorted before having the juice off. Saves half of the working by torchlight and the customer asking when they can have a cuppa etc I like the SBS dual busbar concept but am yet to be converted, mainly because you can only get it from one place and if it's not me who's there next somebody's gonna have trouble adding another circuit if they haven't prepared properly
Usually, we perform all the mechanicals first and only pull the plug at the last minute, but here the homeowner was away. No real reason for the garage being on a 16 instead of a 20; the demand in use there is unlikely to really tickle either. The one-source issue could be a risk, but SBS have been around for a few years and the gear is made by DL who produce other brands such as LIVE. If they go belly-up, there'll be a few pointing and laughing at me, but I don't see them being any worse risk than other manufacturers such as CP Fusebox.
Great video thanks for giving up valuable beer time to do the editing you have been missed. Nice to meet Linda but hope to see Nigels happy face on the next vid🤣
Great video as always. As far as consumer units go, I love the resi9 XE from Schneider, don't know if you can get them there but they are great. Push fit connections, no bus bar because it's the actual rail that replaces it. They make for a really tidy set up.
Cheers chief. Where in the world are you based? I've heard good things about the Schneider stuff, but pricing here is near fifty quid a pop with tax for the RCBOs in that range and most of my domestic clients would tell me to bugger off if I offered such!
I'm in France. I had a quick look on the internet to see if Schneider offered the XE range there and I couldn't find it on their website. It is expensive here too compared to other stuff, I just thought about it after the comments you made about stopping people fucking about with the units and this one is absolutely perfect for that. Again, great video, very informative and fun at the same time, keep up the great work.
Try the Schneider easy 9 or acti 9 PON boards. Very neat and well thought out. Most places with do offers if you want to stock some gear so buy in larger quantities.
Great content dave, always a great watch. Love them boards,so tidy,will be fitting my first one soon. Three more videos this week, I'll have to rearrange my schedule
The spd throws the tail line off I think. No design change for the accommodation of the extra gear upfront of the main switch. I bet Nick was twitching when he saw this and threw some bendy at his screen. 😂 Nice neat job and I like the look of that board.
A good observation Peter, I hadn't considered that. Still, I don't think the 35mm knockout would be in-line enough. They really need those knockouts to be at either end for left/right switch configuration and two together for SPD/non-SPD configuration.
@@dsesuk yarrrrrp. :) knockouts rarely line up up with where they are needed. It would be better if the manufacturers didn't bother and left it to the installer to bosch them out where needed. You may have suggested this in a previous video or was that the other upper middle class hobo you tubing lecktrishan?
Linda's great and will hopefully be doing some more collabs with us. She ticks the boxes for swearing and boozing and that's always important in a co-worker I find!
Lovely to see Linda on the video great work both. Sounds like Nigel has suffered an awful injury. Hope he feels more like his perky self soon. Nail puller! Now where would one get those? Love it!
@@dsesuk thank you kindly! Gonna get that ordered right now. Dont want to damage it on his head. I find the regs book works best for that. Its normally out of date in time for the next recording.
*One* socket off a 30A mcb - the cable is protected by the 13A fuse in the sockets plug. Fine. Two sockets off the 2.5mm cable is also acceptable, as two 13A plug fuses is 26A with cable rated at 27amp. Over the three sockets is a *no, no.*
I must try one of these, how do they fair against fusebox, Ps "Pablo gets around". PS yours videos are far more down to earth and enjoyable than the EV guy with the clean nails, bespoke coffee maker and ever increasing staff.
The last CP Fusebox CU I bought was in early 2020 for the Manor House job. Some have bemoaned the quality of their wares dropping since then, but I haven't bought any CPF stuff lately to be able to confirm or deny that. In 2021, the only CU's I've fitted, and I haven't fitted many, are three SBS boards, one M2 and an Elucian which will appear in a future video. I like what SBS offer, but they need to get their website up and running properly; it's letting them down.
Another enjoyable video, Dave lad. Would it not have been better to fit new tails to the new CU and replace the Henley block with a 100A isolator? The very old tails between the meter and isolator would then have been replaced next time the meter is exchanged.
Yeah, that's a good shout. Fitting an isolator is always the best idea. I didn't do this one as intended, more on-the-fly on the day which, with hindsight, perhaps wasn't the best way. It was billed as a one-off-one-on replacement rather than a relocation, so I moved the goalposts when I got there and perhaps didn't do it in the best way.
@@dsesuk Thanks for such a quick reply, Dave. I know what you mean, some jobs don't pan out as expected and it's always easier with hindsight. If you do more work there, hopefully you won't need the services of Pablo again! 😉
Cheers David for another great video, and it's a pleasure to support you with a few coffee's. As I said to you on Twitter we should all be supporting the independant content providers we enjoy watching.
Ahh great video and great to see you again! I see not having to deal with Nige's pratting about has meant you're able to get a video to us !(Though he was sorely missed)
As a consumer the last thing I would want would be a CU which in practice is sourced by only a few electricians. I have just had a new gas boiler fitted and I insisted that the plumber installed a Baxi purely because I know that in 10 years time I will be able to get spares for it from a variety of sources whereas it might be a lot more difficulot for the European unit he was offering as being better value.
I understand that, but by the same token it prevents the iffy types from making modifications which aren't in your best interests. There are so many corner-cutters out there, anything that can be done to minimise their negative impact on your home has got to be a good thing.
It's not sourced by a few electricians, it's sourced by qualified electricians, also no actually brand is safe we had MK where they been in business for decades but they stopped selling CU a few years ago now
@David Savery Electrical Services as long as it's not giving the less conscience members of the trade an excuse to fit a brand new unit under the guise of "you can't get the spares for this stuff" and replacing the lot with whatever is cheapest at B&Q
We had Baxi boiler and it broke down all the time. Useless. CP fusebox are relatively new to the market but that doesn't stop me using them after seeing many UA-cam installs. I'm all for using new advances and take David's usage as he's done the research and will be worth trying.
Nothing is guaranteed for ever. Proprietary goods are never a good idea in my opinion. If the CU has a fault in 10 years and you can't get a part you are stuffed and it'll cost more. Perhaps the electrical industry should bring in lots of regulations to stop diyers dabbling! What they have I hear you say!
Happy days bit like old school transport! Did you ever finish that Manor House project? How long has Linda worked with you? Was a pleasure seeing a great potty mouthed female on the video, just like my Mrs! Have a great evening!!!!
@@michaelanderson8010 Yeah, the Manor House is done for now and has been for about a year. I need to get jiggy editing the remaining video! I think that's next on the list. Linda's not on the payroll, but I'm sure she'll appear again!
@@dsesuk Excellent, looking forward to watching it! It was great how she didn’t get offended by anything and cracked on with the banter!!

Thanks to you guys filming this stuff on UA-cam, I decided to sack them off and went self employed!!
Brilliant and thoughtful at the same time a difficult feat to achieve. Send my regards to the firm’s genius Nige hope he gets better. Kudos to you for sharing your knowledge to the young ones.

My old video cameras are just that George; you're lucky we're not filming onto VHS here! As for the little details, if you saw me and Nige in HD, you'd bring up your breakfast.
There's a very kitsch doorbell on the end of it that the trendy homeowner who has just bought the place wants to retain, so yes, it remains in service!
@@dsesuk i know some times when you mess with them old things they can fall apart. Them consumer units look decent install a fuse box the other day might give yours a bash next
@@gd-bq7em Well worth a look. I never did find an Amendment 3 CU I was truly happy with, but these are coming close for me. It's only the out of line tail CU entry point that lets them down.
It’s a good job Bless her , she’s got a mind broader than Nigel’s bum / smile. I’m assuming it’s MCBs you are referring to as regards double pole , many countries have had these for years . I could never understand why the U.K. was reluctant to adopt it , after all RCBOs are double pole . Funny I never minded DB changes especially if it was a nice big three phase project . Happy days anyway I enjoyed the video, and sincerely hope the good lady had not needed any therapy after her day with your good self , what you like 🤣 I don’t know Best wishes and kind regards to you both 👍👍👍. Ps hope Nigel is soon back in the saddle riding shotgun .
Yeah, I don't know why we do things differently over here. Not all RCBOs are double-pole - some only switch the line, although these days the new Type-A new models tend to be. Hopefully Nige will be back on the next one when he recovers from his bottom bother!
David you keep banging on about this Radial 2.5 ( on a 32amp)from the board( that serves a ring final circuit too) which was perfectly acceptable in my training with the CTIB ( Construction Industry Training Board ) back in the 15th Edition and actually published this in their edition of the book .As you say is considered acceptable by expert bodies still today. Cannot see your logic which does not accept this when you can still run a single 2.5 t&e from ANYWHERE IN THE RING which I am sure you have done BEFORE on many occasions. I have left comments before all good may I add but another video springs to mind where you had difficulty grasping the guy which used for want a better word the leap frog method of wiring the ring and branded the guy an antiquated old sparky when in fact this is a very common method and even e-fix on u-tube say this is the best method for load sharing .I served the Full Apprenticeship inclusive of the CITB Training.
I'm not saying it's wrong jj, simply that it's not in the spirit of Appendix 15. In this case, it's a 2.5mm on a 30A fuse serving multiple sockets which doesn't meet what Appendix 15 allows. A spur is a spur, whereas a new circuit serving multiple outlets in 2.5mm on a 30/32A supply is not a spur, it's a break against the design criteria we're supposed to apply. There's no difficulty grasping anything at this end, it's all listed in black and white in BS7671.
Nice one David , it seems like an eternity since your last video........Linda seems like a nice girl , those cu's look decent I tried to find the website to have a proper look but failed to find it..... Cheers mate....👍
I just don't get what some manufacturers think. It's like the Lewden SPD board I looked at a couple of years ago where they configured it so the 35mm knockout was on the opposite side to the main switch. They know you're bringing tails into it - that's what it was made for, so why's the hole on the wrong flimmin' side?! After that vid, Lewden contacted me to say they were going to change it, and kudos to them for doing so, but how did it ever go to market without someone spotting what would be immediately obvious to anyone trying to install the thing?!
Hahaha, Pablo. Some say he arrives and leaves with the speed of a Spanish galleon at full sail in a storm, others that he's a myth, nothing more than the drunken tales of old sparks :)
Why didn't you leave the Henley blocks in place and future proof the tails to 25mm Flexi tails. Then you'd have had half a chance of getting the tails clamp in too...
I used 25mm Flexi-tails on the SBS board I installed the prior week and even then couldn't get them through the clamp. The bend radius from the knockout through the clamp is too tight for 16mm tails or 25mm flexi-tails. It *is* physically possible to do, but hard work to no advantage, and one generally has to employ pliers to make the bends which risks damaging the insulation. For me, the tails clamp is bin-fodder every time. The design simply doesn't work as-is.
This installation is on the same estate as my gaff John so I'm familiar with when it went in. This land was bought from the brewery that owned it (curiously enough) in the mid-Sixties and these properties were thrown up at the end of that decade. Some still only have three circuits, cooker, lights and sockets and 60A supplies. My own den-of-shame is stuck at 60A which is why I had to install the Garo priority unit to load share between my shower and EV charger.
@@dsesuk HMG wants us to all go all electric. Who pays to upgrade the electrical supplies. 60A is way too low a limit. Third world. A gas combi boiler, just a small box on the wall, pushes out the kW for DHW delivery. W Bosch have a *50kW* model! This is 217 amps if it was electric. A domestic gas meter can supply approx 62kW. To get say 35kW of instant electrical DHW, you need 152 amps. So a three phase supply is really needed. The max on single phase is 11.5 kW, which will give less than half of a small gas combi in litres/min DHW delivery. Although you could double them up then draw 98 amps, to get decent DHW flow rates Looks like electrical DHW will be stored hot water, which takes up space. Space not available in flats. Progress they say. But SunAmp make small thermal stores giving instant mains pressure hot water. They are _smallish,_ they store heat in a gell not water. A DHW take off coil is inside. Also aerated Raindance shower heads only draw 9 litres/min mixed. An excellent advance. Expensive but they help. The point is the electrical systems are too small for modern homes, even flats. Minimum of 150 amps is needed. Who pays to update the supply to your meter, because HMG are forcing this on us?
@@dsesuk A year on. AFDDs are now here, _mandatory_ in some situations. The three circuits Dave mentioned came to mind - and hence the good old reliable final ring circuit popped up. A guy I know was renovating his two bedroomed flat, that needs an AFDD on any circuit with a socket on it, as per regs. He was talking to me about it. His budget was not big so had to keep expenses to a minimum when pushed. He has a gas combi so heating and hot water is not an issue. The cost of a number of expensive AFDDs was troubling him. so I made suggestions. *1)* Have all the flat on one final 32A ring circuit; *2)* Lights on one 3A DP RCBO; *3)* Buy the Bosch hob model that has a 13A plug on it (their specs confusingly say it is 16A), on a 4mm cable from the CU; *4)* The 3kW (13A) oven taken off the same 4mm cable as the hob; *5)* Oven and hob have 20A isolator switches in adjacent cupboard hard wired in (no socket so no AFDD). *6)* The oven & hob cable is on a 32A DP RCBO; So, *three circuits:* *i)* Sockets on a 32A AFDD; *ii)* Lights on a 3A DP RCBO; *iii)* Oven & hob on a 32A DP RCBO. So, if there is a problem on any circuit, overcurrent, fault, or earth leakage, only that circuit trips out. Sockets have the added arc protection. This also means a cheap smaller CU unit, that takes up little space. I told him the ring may be unbalanced when high current white appliances in the kitchen are all drawing current. I suggested having the ring in 4mm, the oven & hob on 4mm and the lights 1.00mm. This meant it was cheaper for cable as big drums of 4mm cable are cheaper per metre. But he needed a small amount of flex 2.5mm cable. I told him to have 32A Wagos at the back of the socket boxes that take the rings 4mm cable load, not using the sockets terminals as junction boxes. So from the Wagos, the 4 inch long flex 2.5mm cable is taken to the sockets making each socket a spur, and easy to push into the backbox. The 4mm is now static. The socket then only draws current when it is switched on and no more than 13 amps on the terminals at the rear. Even if the ring is cut in half, the 4mm will not overheat. Look at the Continental setup. There will be a plethora of breakers in the large CU and expensive cable all over the flat serving the radials. This works a treat. Very safe as well. All due to the ingenious simplicity of the final ring circuit, which creates a cable busbar around the flat. We do not need circuits for the sake of circuits.
According to Dr. Google, H.A. Nunn & Son stopped trading sometime between 1991 and 1993. The owners must be long gone as their birthdates are 1912 and 1937. I could not find anyone on LinkedIn etc. who had H.A. Nunn & Son publicly listed as their previous employee.
I guess they started tuning out just as breakers were coming in to replace the rewirable and cartridge fuses and with RCDs for additional protection on the horizon. I wonder what they thought of those innovations?
In my trade, 20 or so years ago, it was all leaded components; circuit boards and wires with a bit of computer work. Now it's 95% software and all Internet Protocol. Some of the old guys really struggled with all the "new stuff" and many of the dealerships I dealt with back then, went out of business simply because the staff couldn't get their head around it all. H.A. Nunn & Son seems to have been a family business and possibly the children weren't interested in taking over.

Great video regards diy and not selling to public as a safety concern that's brilliant, so let's also stop the Sunday DIY mechanics from buying steering racks and brake components unless they are qualified mechanics, all my electrician m8s will love that one as they love cars.
Personally, I'm not one of those who calls for the likes of B&Q to be unable to sell CUs to the great unwashed, but there are some out there who want to see that happen. For them SBS provide what they want - a trade-only option that you really can't shonk another brand's wares into.
@@dsesuk that's fair, but I know many electricians who work on their 4 wheeled vehicles, and do mechanics think they should not work on crucial vehicle systems. Many electricians are well capable of doing any jobs, what people forget I suppose is a vehicle could wipe out a coach load of people on a motorway. Do i think brake and steering parts should be banned from sale unless you join the mechanic club.
I detest this _sell to trade only._ The law says anyone can sell to anyone. DIY is not an issue. The biggest issue is uneducated & inexperienced people charging for the poor work they do, to unsuspecting customers. Poor workmanship will *not* go away. It is best to design products that are more foolproof when fitting. Then safety levels rise. Less injury and deaths.
It's a fine line Henry, and I say that as someone who volunteers at a repair cafe where I, along with others, attempt to bumble through repairs of various toys, furniture and appliances. As someone who learned a lot from pulling things apart as a kid, I don't think DIY should be discouraged or that all DIY is bad, but I've just seen so much that is iffy to the point where blind luck has often been the only thing that's saved the day. I don't want to stop anyone from having a go, but I do want to highlight the potential implications. And make it awkward for them, as that's just good for business!
Love the content but think some trunking and an isolator would do wonders here.

@@dannyboisparky Well, there's no point only showing the slick jobs that always go according to plan. Does you good to throw onto here an honest account of how the day went sometimes!
Yes trunking would have been much better - and a main isolator fitted. Trunking always makes a job look more professional looking. Customers are impressed. Also a quicker job overall. Just put the cables inside the trunking once the trunking is up with holes drilled in. Trunking could have gone down the right of the meter near the soil stack, then over the top of the CU. Trunking is quick to fit. Trunking looks more professional when you have an angle saw to get the nice snug fit 45 degree cuts.
@@dannyboisparky
Surface work should always look good. Personally I would have considered removing the ugly old fashioned wooden board. The cable from the main DNOs mainfuse into trunking above it, with a main isolator and the meter's cables running in and out of trunking not seen, or little of it seen.
Hi David and co. Regarding dual busbar boards, the French have been using them for years. 20 years ago I rewired my house in France and the board had dual busbars and double pole MCBs. The incoming supply had a 100mA RCD included and the board was protected with a 30mA RCD. The village was supplied from a 3 phase supply with the houses supplied from 2 phases giving 230V. This meant that the conductor used as the neutral wasn't really neutral! Single pole switched lights still had dangerous voltages on the "neutral" The village supply has all been changed now to something more sensible! I am a keen DIY / Electrical and Electronic Engineer and think your videos are great. I have learned a lot from guys like you on UA-cam. Keep up the good work, and the banter!!
Yeah, I hear dual busbar is common on the continent so I'm not sure why manufacturers do it differently for the UK. Dual busbar makes a lot more sense to me!
So the wiring there is presumably approaching 60 years of age? Any thoughts on when/if one should recommend a complete re-wire on the basis of future viable lifespan? Or do you feel the IR readings and/or any Earth-leakage tests is sufficient to gauge servicibility?
You have to take each installation on its merits of course and make an engineering determination. In this case, nobody had messed with the wiring since the original build, with the exception of the cooker circuit modified to a socket endpoint by the new owner, so it was all as-built and pretty solid. The endpoints need refreshing; new lights, new socket outlets, but the new owner doesn't have plans to make many modifications outside of the kitchen. We could rip out and start again, but it's good copper, the insulation is bearing out, no major changes are planned, so why go to the expense?
SBS is *two* busbars Line and Neutral. The Continental makes like, LeGrande, Garo and Schneider have _twin_ busbars where the L & N are all in one unit. Schneider call it a comb. Schneider and Garo makes are now on sale in the UK, and about time! The Schneider multi-row CUs are now sold in S'fix, even the DP MCBs.
Great video. Very entertaining. You two should have your own sit com.

@@dsesuk Lets be honest the only way to look at any social media is to be under the influence, it's a must for looking at the cesspool that is Twitter 🤣

Best wishes to Nigel - but Linda was fun 🤩
Some decent trunking would have looked better, but originally it was just supposed to be a like-for-like swap rather than a relocation job. One of those on-the-fly ideas that maybe didn't work out as aesthetically as it could have.
@@dsesuk so why did you not mount the db in place of the old instead of jointing all the cables and also why does the db have to be metal with a plastic adapter box above as a joint.
@@scottsparky1 The whole plastic thing is a nonsense in my opinion Scott, but it only applies to switchgear and even then not to DNO equipment, so the DNO can install an isolator in a plastic box, but if I put one in it's supposed to be metal. My NIC assessor had me on that recently as I'd installed a KMF switch on a domestic property. It was inside the coal hole so not actually inside the property as such, but he did me for it not being metal. I don't know why I decided to make life more difficult by relocating it, I just felt it would be better for it to be more accessible.
@@dsesuk
The CU is best where the residents can access it. You did right in moving the CU to a sensible height.
On my second SBS board and this one's a biggy with standby generator and 18 circuits, can't fault it, the delivery, service, price and quality are excellent.
i employed a girl 20 years ago after my local college asked me so she could finish her last year at college as i have took foreign exchange students in the past for them , it was horrendous as every job customers / staff just kept talking to her as girls were never seen and innuendos from staff and customers had me petrified of prosecution , she finished her time and left , and my nerves returned to normal and the work returned to its normal pace . now we see lots more females and linda has done a good quality job with you
Sounds like a shit situation all round. Hopefully, the landscape is shifting and people can be appreciated for their skill and knowledge of the job over anything else.
Lol... 😂👌 Excellent video Dave & Linda.. That was different.
We have had similar single mod rcbo's with a dual bus-bar connection in Ireland for a while but because of the small connections in the bus-bar the biggest cable that fits into the bus-bar is 6mm panel flex with bootlace ferrules so you can only fit a few rcbo's rated at 20 amp or smaller on one dual bus-bar not to overload the 6mm, that does not seem to be a problem with the SBS board the pictures or the SBS board are never clear enough to see how the bus-bar connects to the main switch, they do not sell the single mod rcbo's with the blue neutral lead in Ireland which is a pity they seem a good idea
Maybe I should pull apart the next one to take a closer look at the busbars and main switch arrangement Paul. These are all 100A rated of course. I'll have another one to fit in the coming weeks.
@@dsesuk Thanks for replying so quickly, the main bus-bar in distribution boards over here for mcb's and dual bus-bar for the larger rcbo's are normally rated at 80amps I just had a look in my van to check the size's but there is nothing written on the small dual bus-bar for the single mod rcbo's I guess they are rated less than 80 amp because they look so small but maybe I'm wrong as usual I will have to find out what they are rated at but as I said above 6mm cable is the largest feed you can connect, so long as they are rated at 40 amp or larger that's OK in Ireland.
Good to see you back again...excellent video....as usual :)
Cheers Steven, good to see you back again yourself!
Any good reason for putting the garage on a B16 rather than a B20?
I feel you missed a trick with moving the board; when I'm doing that sort of upgrade I get it mounted, connect up all the extension pieces and get as much as possible sorted before having the juice off. Saves half of the working by torchlight and the customer asking when they can have a cuppa etc
I like the SBS dual busbar concept but am yet to be converted, mainly because you can only get it from one place and if it's not me who's there next somebody's gonna have trouble adding another circuit if they haven't prepared properly
Usually, we perform all the mechanicals first and only pull the plug at the last minute, but here the homeowner was away. No real reason for the garage being on a 16 instead of a 20; the demand in use there is unlikely to really tickle either. The one-source issue could be a risk, but SBS have been around for a few years and the gear is made by DL who produce other brands such as LIVE. If they go belly-up, there'll be a few pointing and laughing at me, but I don't see them being any worse risk than other manufacturers such as CP Fusebox.
@@dsesuk Thanks for taking the time to reply; I get what you mean about the boards

I'm sure NIge will be back, as miserable as ever, once his cheese problem clears up.
Great video as always. As far as consumer units go, I love the resi9 XE from Schneider, don't know if you can get them there but they are great. Push fit connections, no bus bar because it's the actual rail that replaces it. They make for a really tidy set up.
Cheers chief. Where in the world are you based? I've heard good things about the Schneider stuff, but pricing here is near fifty quid a pop with tax for the RCBOs in that range and most of my domestic clients would tell me to bugger off if I offered such!
I'm in France. I had a quick look on the internet to see if Schneider offered the XE range there and I couldn't find it on their website. It is expensive here too compared to other stuff, I just thought about it after the comments you made about stopping people fucking about with the units and this one is absolutely perfect for that. Again, great video, very informative and fun at the same time, keep up the great work.
@@simplyshaker Ta. It looks like CEF can source their stuff, but it isn't cheap.
Try the Schneider easy 9 or acti 9 PON boards.
Very neat and well thought out.

Great content dave, always a great watch.
Love them boards,so tidy,will be fitting my first one soon.
Three more videos this week, I'll have to rearrange my schedule
Good to hear you're giving them a go David - I hope you get on with them!
The spd throws the tail line off I think. No design change for the accommodation of the extra gear upfront of the main switch. I bet Nick was twitching when he saw this and threw some bendy at his screen. 😂 Nice neat job and I like the look of that board.
A good observation Peter, I hadn't considered that. Still, I don't think the 35mm knockout would be in-line enough. They really need those knockouts to be at either end for left/right switch configuration and two together for SPD/non-SPD configuration.
@@dsesuk yarrrrrp. :) knockouts rarely line up up with where they are needed. It would be better if the manufacturers didn't bother and left it to the installer to bosch them out where needed.

@@dsesuk thank you kindly! Gonna get that ordered right now. Dont want to damage it on his head. I find the regs book works best for that. Its normally out of date in time for the next recording.
*One* socket off a 30A mcb - the cable is protected by the 13A fuse in the sockets plug. Fine.
Two sockets off the 2.5mm cable is also acceptable, as two 13A plug fuses is 26A with cable rated at 27amp.
Over the three sockets is a *no, no.*
I must try one of these, how do they fair against fusebox, Ps "Pablo gets around". PS yours videos are far more down to earth and enjoyable than the EV guy with the clean nails, bespoke coffee maker and ever increasing staff.
The last CP Fusebox CU I bought was in early 2020 for the Manor House job. Some have bemoaned the quality of their wares dropping since then, but I haven't bought any CPF stuff lately to be able to confirm or deny that. In 2021, the only CU's I've fitted, and I haven't fitted many, are three SBS boards, one M2 and an Elucian which will appear in a future video. I like what SBS offer, but they need to get their website up and running properly; it's letting them down.
You forgot ‘ awesome’ and tool of the day !
@@rogerbean393 And the Toby Carvery.
Another enjoyable video, Dave lad. Would it not have been better to fit new tails to the new CU and replace the Henley block with a 100A isolator? The very old tails between the meter and isolator would then have been replaced next time the meter is exchanged.
Yeah, that's a good shout. Fitting an isolator is always the best idea. I didn't do this one as intended, more on-the-fly on the day which, with hindsight, perhaps wasn't the best way. It was billed as a one-off-one-on replacement rather than a relocation, so I moved the goalposts when I got there and perhaps didn't do it in the best way.
@@dsesuk Thanks for such a quick reply, Dave. I know what you mean, some jobs don't pan out as expected and it's always easier with hindsight. If you do more work there, hopefully you won't need the services of Pablo again! 😉

@@dsesuk ooh also, are all main fuse pullers called Pablo or are you and Chris CJR using the same guy?
@@qwertycat741 It is a weird coincidence.
As a consumer the last thing I would want would be a CU which in practice is sourced by only a few electricians. I have just had a new gas boiler fitted and I insisted that the plumber installed a Baxi purely because I know that in 10 years time I will be able to get spares for it from a variety of sources whereas it might be a lot more difficulot for the European unit he was offering as being better value.
I understand that, but by the same token it prevents the iffy types from making modifications which aren't in your best interests. There are so many corner-cutters out there, anything that can be done to minimise their negative impact on your home has got to be a good thing.
It's not sourced by a few electricians, it's sourced by qualified electricians, also no actually brand is safe we had MK where they been in business for decades but they stopped selling CU a few years ago now
@David Savery Electrical Services as long as it's not giving the less conscience members of the trade an excuse to fit a brand new unit under the guise of "you can't get the spares for this stuff" and replacing the lot with whatever is cheapest at B&Q
We had Baxi boiler and it broke down all the time. Useless. CP fusebox are relatively new to the market but that doesn't stop me using them after seeing many UA-cam installs. I'm all for using new advances and take David's usage as he's done the research and will be worth trying.
Nothing is guaranteed for ever. Proprietary goods are never a good idea in my opinion. If the CU has a fault in 10 years and you can't get a part you are stuffed and it'll cost more. Perhaps the electrical industry should bring in lots of regulations to stop diyers dabbling! What they have I hear you say!

David you keep banging on about this Radial 2.5 ( on a 32amp)from the board( that serves a ring final circuit too) which was perfectly acceptable in my training with the CTIB ( Construction Industry Training Board ) back in the 15th Edition and actually published this in their edition of the book .As you say is considered acceptable by expert bodies still today. Cannot see your logic which does not accept this when you can still run a single 2.5 t&e from ANYWHERE IN THE RING which I am sure you have done BEFORE on many occasions. I have left comments before all good may I add but another video springs to mind where you had difficulty grasping the guy which used for want a better word the leap frog method of wiring the ring and branded the guy an antiquated old sparky when in fact this is a very common method and even e-fix on u-tube say this is the best method for load sharing .I served the Full Apprenticeship inclusive of the CITB Training.
I'm not saying it's wrong jj, simply that it's not in the spirit of Appendix 15. In this case, it's a 2.5mm on a 30A fuse serving multiple sockets which doesn't meet what Appendix 15 allows. A spur is a spur, whereas a new circuit serving multiple outlets in 2.5mm on a 30/32A supply is not a spur, it's a break against the design criteria we're supposed to apply. There's no difficulty grasping anything at this end, it's all listed in black and white in BS7671.
copper-clad PVC... sounds safe.
Dave you always crack me up 😂👍👍
Nice one David , it seems like an eternity since your last video........Linda seems like a nice girl , those cu's look decent I tried to find the website to have a proper look but failed to find it.....

Their website is sbstradesales.co.uk *but* it's just a holding page at present pending a new site going up.
double pole is the way too go!, and I agree with those clamps its a idea in principle is good but practical just gets in the way.
I just don't get what some manufacturers think. It's like the Lewden SPD board I looked at a couple of years ago where they configured it so the 35mm knockout was on the opposite side to the main switch. They know you're bringing tails into it - that's what it was made for, so why's the hole on the wrong flimmin' side?! After that vid, Lewden contacted me to say they were going to change it, and kudos to them for doing so, but how did it ever go to market without someone spotting what would be immediately obvious to anyone trying to install the thing?!
Hahaha, Pablo. Some say he arrives and leaves with the speed of a Spanish galleon at full sail in a storm, others that he's a myth, nothing more than the drunken tales of old sparks :)

When I phoned my DNO they said Pablo was on a weeks holiday, but they could send Maria and she turned out to be Pablo's sister 😁🐓
It truly is a small world.
Why didn't you leave the Henley blocks in place and future proof the tails to 25mm Flexi tails. Then you'd have had half a chance of getting the tails clamp in too...
I used 25mm Flexi-tails on the SBS board I installed the prior week and even then couldn't get them through the clamp. The bend radius from the knockout through the clamp is too tight for 16mm tails or 25mm flexi-tails. It *is* physically possible to do, but hard work to no advantage, and one generally has to employ pliers to make the bends which risks damaging the insulation. For me, the tails clamp is bin-fodder every time. The design simply doesn't work as-is.

That diet worked wonders
That installation looks 1950s not 1960s.
This installation is on the same estate as my gaff John so I'm familiar with when it went in. This land was bought from the brewery that owned it (curiously enough) in the mid-Sixties and these properties were thrown up at the end of that decade. Some still only have three circuits, cooker, lights and sockets and 60A supplies. My own den-of-shame is stuck at 60A which is why I had to install the Garo priority unit to load share between my shower and EV charger.
@@dsesuk
HMG wants us to all go all electric. Who pays to upgrade the electrical supplies. 60A is way too low a limit. Third world.
A gas combi boiler, just a small box on the wall, pushes out the kW for DHW delivery. W Bosch have a *50kW* model! This is 217 amps if it was electric. A domestic gas meter can supply approx 62kW.
To get say 35kW of instant electrical DHW, you need 152 amps. So a three phase supply is really needed. The max on single phase is 11.5 kW, which will give less than half of a small gas combi in litres/min DHW delivery. Although you could double them up then draw 98 amps, to get decent DHW flow rates
Looks like electrical DHW will be stored hot water, which takes up space. Space not available in flats. Progress they say.
But SunAmp make small thermal stores giving instant mains pressure hot water. They are _smallish,_ they store heat in a gell not water. A DHW take off coil is inside. Also aerated Raindance shower heads only draw 9 litres/min mixed. An excellent advance. Expensive but they help.
The point is the electrical systems are too small for modern homes, even flats. Minimum of 150 amps is needed.
Who pays to update the supply to your meter, because HMG are forcing this on us?
@@dsesuk
A year on. AFDDs are now here, _mandatory_ in some situations. The three circuits Dave mentioned came to mind - and hence the good old reliable final ring circuit popped up.
A guy I know was renovating his two bedroomed flat, that needs an AFDD on any circuit with a socket on it, as per regs. He was talking to me about it. His budget was not big so had to keep expenses to a minimum when pushed. He has a gas combi so heating and hot water is not an issue. The cost of a number of expensive AFDDs was troubling him. so I made suggestions.
*1)* Have all the flat on one final 32A ring circuit;
*2)* Lights on one 3A DP RCBO;
*3)* Buy the Bosch hob model that has a 13A plug on it (their specs confusingly say it is 16A), on a 4mm cable from the CU;
*4)* The 3kW (13A) oven taken off the same 4mm cable as the hob;
*5)* Oven and hob have 20A isolator switches in adjacent cupboard hard wired in (no socket so no AFDD).
*6)* The oven & hob cable is on a 32A DP RCBO;
So, *three circuits:*
*i)* Sockets on a 32A AFDD;
*ii)* Lights on a 3A DP RCBO;
*iii)* Oven & hob on a 32A DP RCBO.
So, if there is a problem on any circuit, overcurrent, fault, or earth leakage, only that circuit trips out. Sockets have the added arc protection.
This also means a cheap smaller CU unit, that takes up little space. I told him the ring may be unbalanced when high current white appliances in the kitchen are all drawing current. I suggested having the ring in 4mm, the oven & hob on 4mm and the lights 1.00mm. This meant it was cheaper for cable as big drums of 4mm cable are cheaper per metre. But he needed a small amount of flex 2.5mm cable.
I told him to have 32A Wagos at the back of the socket boxes that take the rings 4mm cable load, not using the sockets terminals as junction boxes. So from the Wagos, the 4 inch long flex 2.5mm cable is taken to the sockets making each socket a spur, and easy to push into the backbox. The 4mm is now static. The socket then only draws current when it is switched on and no more than 13 amps on the terminals at the rear. Even if the ring is cut in half, the 4mm will not overheat.
Look at the Continental setup. There will be a plethora of breakers in the large CU and expensive cable all over the flat serving the radials.
This works a treat. Very safe as well. All due to the ingenious simplicity of the final ring circuit, which creates a cable busbar around the flat. We do not need circuits for the sake of circuits.

In my trade, 20 or so years ago, it was all leaded components; circuit boards and wires with a bit of computer work. Now it's 95% software and all Internet Protocol.
Some of the old guys really struggled with all the "new stuff" and many of the dealerships I dealt with back then, went out of business simply because the staff couldn't get their head around it all.
H.A. Nunn & Son seems to have been a family business and possibly the children weren't interested in taking over.
@@dsesuk question for Linda though: is she originally from South Africa?
@@wayne.holmes Yes, she is, hence the twang in her accent!
@@dsesuk thought so! I'm originally from there too but have lived in Germany for 11 years now. We can spot each other by the accent any day :-P
How many years has Linda been qualified?
Dave, why am I getting adverts about meeting missionaries from church of latter day saints?
Who knows how the Google-borg works. Personally, I loathe all forms of religion, so once this copies over to the Odysee platform you can view it there without the brainwashers trying to part you with cash for the promise of a better existence after you've kicked the bucket!
Hello Linda 😎
Great video 😎
Wow. Show us that nail puller in action close up sometime 👍🏻
I think it's in my old Lesser Known Tools video from back in the past Andy!
All good, test came back negative for me and the missus.
Good. There's a backlog of awful stuff here for you to catch up on!
@@dsesuk I'm sure there is ya dickweed. All good means that I don't have covid. I'm still not fixed. I'll be back when you are though. Also, enough talking about my undercarriage.
I thought i was the only one that throw the tails clamps away
Great if they work, spinned into the bin if they don't. I wonder what goes through the heads of some designers who come up with these ideas without ever checking they work in practice.
RIP Nige: 1943-2021
I don't think he's dead, although I do suspect he may be in prison. This 'holiday' followed by sick leave just sounds like he's been sent down for something and is trying to cover himself until his parole comes up.
@@dsesuk if so, we will need to start a petition like deidre rashid
Feel the same about consumer units. Just feel like I’m a massive pain in the customers arse. Puts pressure on me to get the power back on so the customer can get back on to pornhub and charge their rampant rabbits
I don’t have anything witty to say, but great seeing this video.
Thanks Gabriel. Rest assured, I don't have anything witty to say either. At least, not with this morning's hangover!
Nigel is sorely missed, or is his pisser sorely sore? :)
He'll be fine once they've lawnmowed all the mushrooms off.
Excellent. I was beginning to loose hope 🙂
It's been a while, but three more are coming this week Andy, and if you view the channel playlists you can find them before they go public.
hope nigels OK 👍
Dave give this a go may be the future ?? "Wiska WIB 4 Consumer Unit Relocation Kit" Bundy10 will get you a discount
Great video regards diy and not selling to public as a safety concern that's brilliant, so let's also stop the Sunday DIY mechanics from buying steering racks and brake components unless they are qualified mechanics, all my electrician m8s will love that one as they love cars.
Personally, I'm not one of those who calls for the likes of B&Q to be unable to sell CUs to the great unwashed, but there are some out there who want to see that happen. For them SBS provide what they want - a trade-only option that you really can't shonk another brand's wares into.
@@dsesuk that's fair, but I know many electricians who work on their 4 wheeled vehicles, and do mechanics think they should not work on crucial vehicle systems. Many electricians are well capable of doing any jobs, what people forget I suppose is a vehicle could wipe out a coach load of people on a motorway. Do i think brake and steering parts should be banned from sale unless you join the mechanic club.
I detest this _sell to trade only._ The law says anyone can sell to anyone. DIY is not an issue. The biggest issue is uneducated & inexperienced people charging for the poor work they do, to unsuspecting customers.
Poor workmanship will *not* go away. It is best to design products that are more foolproof when fitting. Then safety levels rise. Less injury and deaths.
Everyone’s got a mate who’s an electrician that will get you a CU or whatever
Perhaps. Nobody's saying it's impossible to get the gear, just that you won't find it down B&Q.
Well Linda a lot more palatable to watch helping . Sorry Nigel .
They both fart the same in the cab of the van.
Sometimes I used common sense instead of the regs .
when did you get your wife working for you lol
The (actual) wife does the books, Nige is the work wife and Linda picks up on whatever the other two haven't sufficiently nagged me about.
Lol you should have her on video more
First AmytheSpark, now Linda... Have you changed your aftershave Dave? 🙄
What can I say, my natural musk oozing from my armpits seems to attract the ladies into wanting to discuss electrical installation and testing!
@@dsesuk "Eau de shonk" Haha
Nice one a boozy finish to the day ,that was a lovely pusay wasn't it😄😉
Which do you prefer, short hair or long hair pusay?
So does that mean you have a female stand in for your stunts too David?
Best wishes to Nigel I hope you get well soon.
I asked Linda to jump through a flaming hoop on this one, but she declined because of her constipation and bad back.
I always find someone shining a high power helmet light into my face quite disturbing unless it is for 'entertainment' purposes ...
Makes a change having Linda's shiny helmet in my face instead of Nigel's.
You should be encouraging DIYers, free the world for technocrats :p
It's a fine line Henry, and I say that as someone who volunteers at a repair cafe where I, along with others, attempt to bumble through repairs of various toys, furniture and appliances. As someone who learned a lot from pulling things apart as a kid, I don't think DIY should be discouraged or that all DIY is bad, but I've just seen so much that is iffy to the point where blind luck has often been the only thing that's saved the day. I don't want to stop anyone from having a go, but I do want to highlight the potential implications. And make it awkward for them, as that's just good for business!
