Hey Vie! Nick mentioned you enjoy gymnastics, if ever you are in East Anglia I’ll be happy to open up the gym club I work at (Waveney Gymnastics) the videos your dad have really helped me out along my journey of becoming a sparky so I’d be happy to return the favour!
Great video again Nick. I’m not an electrician but have been watching yours and Adams videos for ages now, I love the detail you go to and the banter you both have. I’m also a fan of Gary and the efixx team, so when I heard the news about his daughter I wanted to do what I could to help so I’ve donated. Keep up the great work guys and all the best to Gary, and Vienna.
Sent a few quid over, watched gaz’s videos for a while now and he’s helped me loads. So hopefully the small donation is a small way of saying thank you
I agree with you 100% on the metal junction boxes above the consumer unit. It's much safer than the multiple plastic boxes and would make any future troubleshooting much easier. As usual, you lads did an excellent job on this one. Looks beautiful and it's far more functional.
only just started watching the video but I wanted to say that I agree with your comment about Gaz, I've got to know him over the past few years and he is 100% the best guy you will ever meet, helped me loads through my apprenticeship and beyond, thank you Gaz!!! Good video Nick, as always!
Nice work, and good to see some metal boxes going in. Always struck me as odd that regs require metal enclosures on DBs but happy to put more connections in a plastic box when extending. Kudos for spreading the word about Gary's daughter too. Nice to see people using their fame for good. :)
My way of thinking is screw terminals in a consumer unit can be either poorly torqued or come loose over time. Wago/crimps/mf connections can’t/won’t so no need for non combustible materials for the enclosure?
@@roydowling2542 it’s all about the probability of loose connections causing an issue. How many fires start in a socket or light switch? How many in a CU ? Do the math
Sorry dude, I totally watched Adam's first..... That dude is a keeper. :) Amazing gesture for the fund page Nick. Donation to follow shortly. Hat's off to you, it's a flappy beanie hat, no Batkid logo and therefore way better.
No... This time I watched Adams first.. Nothing personal It had great content and nicely done, good to see the other side. Well done Adam Obviously you have taught him well
Most sockets and boxes are fairly non flammable phenolic. Yeah there are pvc sockets and boxes, but i'd say they're in the huge minority. Nowt wrong with a little bit of extra safety. And actually metal adaptable boxes can be a dang site cheaper than many of the proprietary plastic offerings
@@TheChipmunk2008 true, I bought some 4x4 plastic trunking once it was twice the cost of metal and I also got a 90 degree bend, that was the same cost as the trunking, couldn't believe it.
Hi Nick & Adam thank you for sharing this amazing video . A quick tip from me, try to use (Phoenix Contact, PT 2.5 WH Feed Through Terminal Block, Push In Termination) in the junctionbox. Btw, so nice of you that you support Gaz in his personal situation. This man has done so much for the electrical community in England & Europe.
Hi mate great channel. I'm a British sparky now practicing gods trade in Australia, once the borders open up you should pop over it's very different and interesting.
Hi Nick. That was another cool gesture, helping the daughter. Well done! Oo-o-o there were some digs at poor Adam. 😆 Its really nice to see how well you work together. Bad enough that you "forgot" your glasses, but you left out whacking your head! You should have "borrowed" the clip from Adam. Too funny! I don't know how many times over the years I've whacked my noggin. It must be made from granite. Just like yours!
I'm not an electrician ( can just about change a light fitting, takes about 4 hrs but hey ho..).. but just like to say top work you do, really neat and great to see professionals at work.. How you can work out where all those wires go is beyond me.. my brain aches just looking at em.. Top job..👍👍
Training and experience help a lot, but notes and labels are where it's really at. You can't get away with "rule of thumb" anymore when you start hitting 200+ cables (not wires) into an enclosure with specific location requirements for termination and internal trunking.
Well said Nick regards Gary and family. You are a wonderful human being buddy. Top work as ever enjoyed it. Maybe ask Adam to give you a shout out. He is pretty bigtime I hear.
Made me laugh. The Posh Part of Stafford 😅... or just where the very short people live! The height (or lack of) that garage with it's even lower roller door... classic. Great video anyway 👍
Great job guys, looked neat Nick. Loved the flexi. Having same problem with arms and neck at the moment - two weeks in a cellar working upwards - ouch!
Very neat, especially those two metal junction boxes, American would make absolutely right mess with those wire nuts which something I would never ever use it!
Good effort with the box, great to see the thought that goes into doing more than the minimum in the regs. Have you used intumescent pads in any installs? Particularly good with things like trunking and rear entry boxes to impede flame propagation. Bit neater and less of a maintenance pain than intumescent mastic. MoD buildings use evirograff pads absolutely everywhere for trunking (including metal) especially between fire boundaries.
Highest load closest to the incomer means that less current has to travel the length of the bus bar, less opportunity for heating and less chance of a problem. In reality the bus bar _should_ be more than capable of carrying full current for it's entire length and so no one _needs_ to do this. But things happen, so it's good practice to minimise a risk if it's possible to do so. Strangely North American codes often require a minimum distance between the incoming breaker and any high load - for airflow / cooling, so they end up doing the opposite: typically incomer at the top of their boards and then load breaker modules upwards from the highest at the bottom. But their bus bars are fixed, usually steel and stoopidly mahoosive! So unwanted heating in the breakers is actually much more likely than in the bus bars.
exactly. the highest current goes the shortest distance (less loss and less heat generated). As you said if the big load is at the far end, the whole busbar is carrying that current end to end, before adding all the other circuits "along the way".
Your bus bar has a small (.0001ohm/cm) resistance and that creates heat which costs money. So your largest breakers are closest to reduce resistance. Though it may be small but over the life of the board could be significant compared to the cost of putting them in order with wire length not being a factor.
Fitted my first FuseBox this week and had a quick look at the instructions, pretty sure it said to put breakers in order highest to lowest from main switch
Highest loads next to main switch is pretty much an urban legend IMHO. Yes, it means the highest current has the least distance to travel down the busbar, but two things: the CSA of the bar is such that it is rated to at least the main switch current anyway, and if you add a shower in 5 years, nobody sensible moves all the existing circuits down the bar (especially not in a 48 way three phase DB 😂😂).
@@TheChipmunk2008 Id love to know what the total is that Vienna needs for the new arm... Think theres enough guys on here to really push it along! I'm a plumber donating via a sparkys video so it must be worthwhile!
My way of thinking is screw terminals in a consumer unit can be either poorly torqued or come loose over time. Wago/crimps/mf connections can’t/won’t so no need for non combustible materials for the enclosure?
With the meter being mounted on a piece of plywood, are you allowed to move that without actually touching the cables on the board? As to rearrange thing's & give more room?
Highest amps closest to the source = Because Heat If they have to go from [A-B] and [C-D-E-F] transmitting less amps wont get as warm and can use the nice thermal conductivity of the copper help bleed heat away and have cooler parts to eradicate the heat. If it has to from [A-F] and go through [B-C-D-E] along the way, it's all being heated up so no nice heat bleeding.
It would be interesting to see Nick test this in his unit. I reckon you would have to be putting hundreds of amps through busbar that size to get any heat effect?
@@fazerstorm-oap If there was any significant heat, then this whole technique would not even be a thing.. Everything is WAY WAY within safety limits.. You are correct, it would take significant amounts of energy.. Even as a giant burst (not likely with fuses) or at limits for a very sustained timeframe with a very high ambient temperature. Lets just say everything else would prob fail before the busbar ever did.. And this is why it's not against regs to do so, just a general guide. Same way driving down a road within mm of the white line.. It's not against road law.. but why not just drive safer by rule, and do things out of the norm when needed.
I like to print off the circuit chart on the install circuit, laminate it and fix it up local to the DB. It does involve another visit to the job though :P
On the subject of standing in awkward places, and bits hurting. Over 10 years of working for a small computer company I often ended up working under desks behind racks working on cables. Twisting my neck into awkward places, not knowing I was gradually damaging my right internal carotid artery. Eventually resulting in a pretty serious stroke in November 2010, leaving me with permanent disabilities. So beware of things that hurt bits of your body, especially your neck!
That box looks neat enough to me. Okay fine it's not ruled to mm precision and perfect parallel lines etc. But it's safe, easy to trace wiring, not over cramped, what's not to like. The real world isn't a college course setup job :)
Get your eyes checked mate you need them more than you know. Would love to donate but I’ve just found out (Thursday) I’m getting the first of my hips done next month then the other ASAP. Love Gaz and efixx and would like to wish Gaz’s daughter all the best. ❤️❤️❤️ P.S GET YOUR EYES CHECKED.
On the busbar thingy - wouldn't it make more sense to have it as close as possible to the main breakers to lower the effects of voltage drop across the bar - all be it it should be in the mV range or the bar is too thin.
The inspection software should support 4" thermal printers - then you can use adhesive label media to print your own circuit detail labels, with your branding, but without need pre-printed labels
In this case "Adam and me" is correct. Just imagine you're missing out Adam (hard though that may be). Would you say "videos from I" or "videos from me"? Putting him first makes no difference: "Adam and I" is only right if you'd say "I" on your own.
Hi great video and nice job but I think your main tails should be insulated and sheathed, looks like they are singles only. With no mechanical protection the insulation is vulnerable. Do you agree?
I suspect a lot of "electricians" think that highest load breaker nearest the main switch=lower voltdrop on the common busbar which while technically correct it's insignificant, you could do a low ohms test along the main busbar to each breaker stub and do the maths, you'll be looking at uV/mV max and it would only ever matter if the ring was loaded to anywhere near it's limit which they virtually never are.
@@mrclive5 Grouping all high load MCBs together generally causes more issues for the MCBs themselves. The contact impedance of the MCB means they will dissipate power under load. There's plenty of reports of overheating under these circumstances. The busbar is rated for the full load across it's length and there is no requirement or reason to group the highest rated MCBs together nearest the supply.
@@sdgelectronics now that's a very fair argument, but in your average domestic install you're highly unlikely to ever see full load conditions on the heavy loads at the same time. And if you do, it'll only be for a short duration. I'd allow diversity here. I've never seen any evidence of MCBs or busbars being unduly loaded, but I'll take what you've said on-board, it's all good info. Seen plenty of cooked cables, and the odd accessory.
@@mrclive5 There's a few pictures on various groups. I might take some measurements of a busbar and see what the implication is in terms of voltage drop of having heavy loads at the end of the busbar. A quick estimation suggests you'd have nothing to worry about though and a logical arrangement e.g. all downstairs circuits together is probably of better benefit.
You bond conductive enclosures (boxes, conduits, ladder trays, etc.) to earth ground so that any exposed conductor trips a breaker rather than shorting to another circuit or making the enclosure live to electrocute someone.
@@mrbeckles77 I'd assume the CSA of the CPC of the highest load contained within the box, on the basis that more than one simultaneous fault would be extremely unlikely. Would like to know the proper answer though.
