Tip for getting the db lids on easily... when fitting the din rail, mount it just tight enough so it moves with a little nudge, mount 4 or 5 mcbs onto middle of din rail, fit db lid on and just start the cover screws, the din rail will align with db cover, use a sharpy, and mark either side centre on din rail and db, pop lid back off, check your markings are still in alignment, and tighten down the din rail screws... when you come to fit the db cover when all is finished it will fit like a treat...
Hey Mark, thanks for the video, it was very informative and I can see you put effort into the installation. I'm not an Electrician, but I am a Commissioning Engineer who works on industrial electro-mechanical equipment. My industry is extremely heavily regulated with regard to safety. Only qualified professionals are allowed to touch the equipment I work on, but all too often a professional makes a mistake and thankfully the additional safe-guards we have in place prevent a serious injury, or death....most of the time. Were we not to take what I call "best practice" safety steps, I know personally of two incidents within my own team where an innocent assumption could have resulted in millions of £/$/€ of equipment damage, or a 3-phase human fry up. A couple of people have commented on the bus bar being left exposed in your installation. I know this is behind the cover with blanks installed on the cover. I know that only an Electrician should ever remove the cover, but I understand where others are coming from (though some could have worded it better). Not everyone, professional, or idiot alike does what they should all the time. So, I personally think it's a cheap and easy safety step to insulate the bus bar within the enclosure, even though I agree that it's insulated from the customer when the cover is on. Every installation I have seen so far had the exposed section of bus bar covered with a plastic strip on the bottom, or where there is a gap between breakers, this exposed section is insulated, or an unused fuse is installed. As you say yourself, you will inevitably have a customer doing something they shouldn't do, so if you are not inclined to leave a magnetic wedge that keeps the fuse board door open for fear the customer will misuse it, would you consider it best practice to insulate the bus bar sections which are exposed if the cover is removed? Again, thanks for the video. I'll be installing a shed consumer unit and the videos on here are full of useful tips from the professionals. I will of course be leaving the final inspection and connection to the Electrician, because I know it would be all too easy to make a simple and costly mistake when it comes time to energise the circuit.
Cheers Gary, full din rail blanks and proper labelling are always used. But I like to demo what comes in the kits etc. A few brands have uninsulated or covered busbars BG are one in some of the range. So it is what it is on that front. This is actually a demo board at apprentice 121 simulating a small flat for learners to practice within. This video is a reference point as part of that to raise discussion points such as yours. I have other boards on the channel with similar reviews and what comes out the box. Cheers Mark
I fitted three of these CUs last year sn none of them included the tool you showed for holding the lid open. I feel deprived, you are a very lucky man to have so many!
Thanks for sharing your videos! It's really cool to see how others work, and like you've mentioned before, it's all about sharing and generating leads. Social media is amazing for learning, entertainment, and marketing. Videos give a voice to those who prefer not to write, allowing them to share their knowledge and skills with others. These kind of videos have helped me a lot.
Love your videos. You always explain thoroughly your thought process and reasons for doing something in a certain way. I’ve learned loads from you and appreciate the time you put in to your content. Keep up the great work.
It’s a sensible thing to do and we always fit din rail blanks which cover the busbar. As this is pre testing and final commission we are not at that stage yet. Thanks
Nicely explained video. 👍 The front cover setting used to be a lot worse on the large boards as the din rail only had end supports and so used to bend really easily. They added centre supports to fix this. As you say, it’s nearly there but still can be a fiddle.
Yes it was a lot worse before. I think tbh my struggle getting the busbar in set that in motion as I didn't quite have the mcbs and rcbos lined through.
Keep doing what you're doing. There's always going to be people critiquing but from what I have seen it's unjustified. I use a plastic mirror insulated with sleeving to inspect, found it handy for busbar. Alternatively there's an orange variant available!
Great tutorial, excellent and tidy installation! Can you post a link to the Knipex flat cable stripper and more importantly, the "weir cropper" you mentioned?
Nice clean demo Mark, I must try your technique of laying down the Neutral fly leads to the bottom of the board and bring them up at the end, I usually try and tuck them under the tops of the ones to the right as I fit the RCBO's, as for the keyboard warriors you know what they can do with a pair of croppers
Great video and super useful tips on making inside CU neat and tidy. Much appreciated. What is your view please on stranded vs solid core cable. I believe the cables you worked with in this video are solid core wire. Do you ever use stranded cables in domestic wiring please? Thank you.
In the UK we have stranded cables but they tend to be on final accessory connections such as lighting pendants, immersion elements, heating controls and more recently some EV ultra cables. Those get ferrule crimped on the end. The fixed wiring is generally solid or 7 strand.
Everyone says it’s easy, but I usually encounter a problem and it will take the whole day, 6am till late at night, I’ve only have one easy board change, and what if you encounter a shared neutral on the lighting, if you can sort it out on the day, Takes a very long time to sort that out
Thanks Mark, I found this very interesting and informative. One question I have - how did you know which cables were for which circuits? I couldn't see any labelling. What is your usual method for identifying circuits at this stage? Thanks again, very well presented video.
No 🤣 it’s almost like we know how to do the job. I covered torque during the video. I always populate and terminate a board pre testing. I’ve got the inspection mirrors never need them as it’s pretty hard to miss if you know what you are doing.
@@electrician247 ah but complacency can be the ruining of many a good electrical, for demonstrating good practice get the mirror out for these youngsters on the up , theres a good chap 🤣
@@jamiekent1970 feel free to share your own Jamie and I will happily point people at it. Personally I think those mirrors are a pointless gimmick having wasted money on them.

@@jamiekent1970 get your camera out because for every criticism there is countless more who will value and enjoy your stuff. Same as in the real world.
Good job Mark. I have people on the net attacking me, because of dumb reasons, like wiring methods or NEC electric codes, and say I'm wrong about this and that, and just be insulting and rude, and they don't even know me, about my skills and trade knowledge, or education for that matter, but those are just entitled individuals that use Google for their knowledge and education, nothing wrong with that but if they didn't have their phone, they wouldn't be so head strong about every subject. They want you to be nice to them but they get all nasty with you if you don't agree with them.
This video has given me quite a bit to think about regarding my attempts of fitting a board to the point where I think I can save half an hour on my next install. One thing I wasn't clear on is how you mark/ identify your cables at the beginning. Did you number them somehow? Thanks.
Hi Paul, yes number the sheeth to identify. With cables coming in the same entry point you can then transfer that cable ends if its busy in the board. Wasn't needed here as cable entry was separated etc. Thanks
Really great, clear video. I'm considering a career change... from no qualification, to qualified electrician, how long would you say it takes, if you can study full time? Cheers
With the portfolio 2-3 years would be absolute quickest I would say is possible even full time. Plenty are on that path and some told 6 months. Getting the experience is the hard part beyond just the courses etc to complete the portfolio and NVQ.
God people are obsessed with NVQ , take your level 2 and 3 tech certs and complete 2391-52 along with 18th edition and then it’s hard for someone to say you’re not a competent Electrician!
Question, please ecplain the function of the component arangement on either side of the isolator switch that was already nstalled on the rail prior to attaching the rail to the enclosure.
Hi mark, you mentioned using the Wiha 8 in 1 pliers in another video. Could I ask where you get these from as I can’t find any online or on Wiha’s website.
Awesome job! I just have one question. When you are connecting the unit to the main line do you do it with power on it? I am about to install a new unit and I am slightly concern that I may miss something important. I am planning to pas one cable at the time so there is no real danger when toching one one of them or even the metallic box with one of them if the other is properly secured, isnt it? Thanks again for such detailed video.
Those Knipex feed through cable strippers, do you have to do anything special to maintain them. I have a pair that i rarely use as they just mangle the crap out of the cable, if i am lucky i get one clean strip then its back to mutilation again.
He's a question... Another spark said to me, why don't I trim the fly lead on the rcbo, to fit the install, like it says on the installation instructions,... Lol, I said, I just do the same as as what other sparks do 😂😂😂
Some brands state not to cut them. I leave them long when possible so they can be moved if required. But sometimes also trim them. We do what we like 🤣🤣
cor!just imagine if a molecule of oxygen could have found half a second's gap in between a single word to help him to draw breath at any point in time!
@@electrician247 it's not an insult just banter.superb exhibition!we meet people who just sit there and just occasionally grunt!good man!good man!excellent video!
Do you want to quote that reg and I will share it. In a terminal bar with 1mm to fill 2/3 you would need more than doubling over 🤣🤣🤣 If you want to look at the actual fact of the matter different brands have different requirements. Most want conductors under 1.5mm doubled over in terminal bars with no reason to double into a cage clamp. Hope that helps and your welcome anytime at the academy if you want any further help
@@electrician247 isn´t it required to cover the unisolated poles of the busbar? 🕊 /edit: Okay, a few people asked about ist. So it is not required in the UK. Then that´s fine. - Btw I like your argument pro cableties.
From France it is a very dangerous installation...what you have done in 13:38 is completely forbidden!! Not acceptable because there is no protection or isolation ...a copper bar installed like that is not very serious from our standards.. it's possible to cut the copper bar to avoid such a weird installation.. NOT ACCEPTABLE AND NON SECURE..I DO NOT APPROVE
No need for caps it’s weird. The busbar is isolated via the main switch, it is insulated and carries blanking modules for future use. Cutting it is both unnecessary and counter intuitive. It represents no danger to skilled electrical workers or operators and is standard practice in UK systems. Indeed this is as per instructions and regulations. I take your point of view but don’t require your approval 💪

Or mark the din rail before you strip down the db for fitting. In theory, it should align correctly, but we all know not all db's are equal...
