As a responsible Handyman I watch all your videos for information to pass onto my clients, also to deter them from attempting electrical work themselves, I like to stay up to date with regs but know my limitations, thank for the videos.
good man. i'm a fairly enthusiastic DIYer and i've worked in construction on and off over the years, but there are two things i never fuck with: electricity and plumbing. both of them should always be left to professionals, imo
Good luck with your studies and I hope my videos will help you in some small way. If you can share the channel with other learners that would be fantastic. All the best. Gaz 👍
I’m not a sparkie but I’ve always wondered what was inside the consumer unit ! People should watch this next time they moan about having to pay an electrician to do work .... very skilled work. Great video chaps ⭐️⭐️⭐️⭐️⭐️
Not an Electrician but used to be a Wireman, My OCD loves the idea of labelling all of the L,N,G cables up so you can see which one associates with what one.
Nice presentation. :) installing a spare breaker instead of a blank is a nice touch and is something I have started doing. The thing I like about Mr Wichard is he is always thinking about the next guy/lass that may work on the system. :)
I think it's quite offensive to tar all Dodgy DIY Dave's with the same brush. In some cases, I've installed circuits to a higher and safer standard than a 'qualified' 'professional' electrician. Just because they're qualified, doesn't necessarily mean they are going to install your electrics to that standard. I had a sparky come round and they didn't have a clue yet they were a 'qualified' 'professional'
Totally concur there is a certain snobbery with a lot of youtube channels in the electrical area. SAfety should come first always but beyond that giving people the knowledge fairly will always help them make better choices in life than just beating them with a you don't have the right sticker so f off.. As that just leads to well f you back I'll just do it however then. And you will always get a % who just do whatever anyway.
Wish I could uptick a thousand times. Tbf, professionals doing domestic jobs at realistic price to them would have to allow for many hours of scrabbling around with difficult to reach cable runs, carving would, plaster, brick, cement while minding carpet, paintwork, etc. Nobody could afford it. As DiYer, I can take my time and do so. So I install boxes and conduit with strings in if it's a job that requires a pro to feed the cable so they can register it. But all professionals say "Electrician's dream!" then still work fast and cut corners even when I say I'll pay more for more careful work. I have met a diligent sparky and hope he's available for my next project to bring all my electrics up to 2022 full spec in case I have another heart attack and leave wife with an out of date system
Hi great videos, just on your second RCD which is rated at 80A you have connected 40A + 32A + 32A + 16A + 6A which is already over the rated Amps of the RCD.
I have a question Gary, I'm a Maintenance Engineer for an privately owned apartment block, with about 100 apartments, would this be my responsibility to test the RCD, or for the tenant to do?
Interesting that you (and many others) so emphasise a need to switch OFF with no load. That seems to be contradicted by the device rating of AC22A. (Switching of mixed resistive and inductive loads, including moderate overloads IEC60947-3) If it really did expect no-load use, it would be rated AC-20 (Connecting and disconnecting under no-load conditions IEC60947-3) Or am I missing something?
Great videos as always. Thanks for passing the knowledge to others specially youngesters. One small suggestion . It will be a good practice ( safety wise)to tape around the cables that has been striped off and earth sleeving put on.
I would have seen the spare fuse ways and split the rings into two radials and run them through 20amp MCBs. so that the 2.5mm cable is within maximum tolerance .
As an electrical student, I fully agree that consumer units should only be worked upon by an electrician as there’s so many things that can go wrong. “balancing” your consumer unit is incredibly important. Please use a qualified electrician for all your consumer unit needs.
I have had two very expensive pieces of hifi damaged by a lack of surge protection (SPD). It's worth fitting in your own home if changing your consumer unit
Excellent explanation and comprehensive, I'm no sparky but it would have been nice to know the thickness of the cables, in particular the rcd cables. Thoroughly enjoyed it, so I've signed up👏👏
Looking for some advice, I have 3 appliances each allegedly consuming 3050 at maximum capacity, but the wires and my main feed to the consumer unit is getting so hot. I deliberately upgraded my consumer unit so it could handle these appliances. I installed the outlet (Specifically for these appliances) using Prysmian 10mm2 twin and earth, wired to a 50-amp breaker, then installed ANOTHER Prysmian 10mm2 twin and earth, wired to a another 50-amp breaker so there are now 2, one for two lower end of the consumer unit and the other for the higher end. Furthermore, I also have two BG 80A 30mA 2 Residual current device (RCD) installed on the consumer unit and the main feed that powers the consumer unit has a fuse of 100amps. These appliances are in a container where I linked each outlet to one another so they can draw power from the first one (again, each has its own 50-amp breaker at the opposing side of the consumer unit, one for the upper side and one for the lower side), not sure if that is causing resistance as I even have the powercables with 13amp fuses to power those appliances, but since there is a 50amp breaker for each outlet, I’m still confused.
Do you have more info on the surge protectors? Typical schematic and the standard they have to meet? I design lighting products to meet EN61000-4-5. Interested if these meet much higher test voltages ( eg 6kV) and if they have VDR's, gas discharge tubes fitted and auto switch off when a dangerous surge occurs.
Great Video. You specify Turning OFF of CU, but not Turning ON, would Turn ON. Also you introduce SPD, where would SPD go into the CU, should befirst device to capture surge from Lightning? so before or after the Isolator? Is it better to replace the Isolator with an MCB double pole so can switch OFF in LIfe Mode?
Thank You Guys for the video. do you have a video showing the different styles of Consumer Units? We have Surface and Flush Styles here in the US, in the UK, I seem to see a lot of surface mount styles... Is The Flush style common in the UK at all?
In one of your previous videos you showed labelling each live, neutral and CPC so each circuit could be identified for troubleshooting purposes. I take it that isn't a mandatory requirement as I didn't notice any labelling in this video?. Kind regards.

Very good video as it clearly talks through step by step and easy to understand. Only question is,.... How can you tell the wire comming in to the box operates what?
Hi😅 o got led here for a different reason but wow I’m learning 💫 can someone kindly tell me which switch is for the fire alarm - I’m looking to replace battery due to beeping low battery
In the uk we can have ring circuits or ring finals. They allow us to do crazy or cleaver stuff with 2,5mm cable for our socket circuits. It was invented back when copper was in short supply. However it’s so flexible we carry on using it. It is a pain to test though.

Great presentation and learning, I am not trained Electrician however good watch for safety in domestic environment. When testing RCD,s 6 monthly, how does that work? does it trip all the associated fuses plus RCD? What is the best practice? I have B40 directly to my Under Floor Heating via a 45A double pole switch and to the Thermostat. Currently faulting to a blown Thermostat as it is not displaying at all after loss of power in the area. Can you suggest before act on it.
@@tresslerj1985 That's what I do John, although I did build my own 5 bedroom house here in France and did all the electrics which passed the rigorous inspection first time. used to do electronics as a hobby when I was a lad. Used to be an aerospace engineer in the UK before I retired.
It's unlikely you will ever see every MCB / circuit under full load. If you did then that might cause an issue. :) What I was interested to hear in this video was then liking the idea of filling all the slots on the board. In my mind I'd rather have a gap to allow heat dissipation but then again I'm not a sparky or a supplier just someone who likes to learn about everything.
Not a electrician but I have noticed that in my garage some of the sockets when tested show that on a double socket one side will read that its wired correct and then the other will read live and neutral reversed ? Any one know why this is the case if the back of the socket is wired correct ?
Having upstairs lights on one section and downstairs on the other etc is obvious common sense and what I asked for our rewire. Electricians said not necessary. I insisted but they still messed up in two out of 18 circuits.
GSH Electrical it is actually rare for rcbos to be double pole switching. Obviously LandN need to go through them for the rcd sense, however most only switch off the Line. Regards a DIYer who shouldn’t know anything.
Do you talks from normal MCB or RCBO's? This both are two differnt devices. First "break" the line (live/hot) side, the null line go back normal. Second "break" both lines but have a normal MCB and "earth leakage circuit breaker" together inside. [Sorry english people for my bad english tech terms.]
Electrician... somebody of competence. That's the problem. As a DiYer, I'd never do more than switch off circuit breakers at consumer unit. But, as I've mentioned elsewhere, the problem is finding a diligent professional. They all might be registered as competent. That does not mean they apply that registered competence in a diligent pride in work way after getting registered

Nice vide guys, could you do a presentation on regulations 536.4.3.2 and 536.4.202 on the selection of switch gear and RCDS, in that we can't just use diversity alone.
I'm a spark but not domestic. I've always wondered why the main switch is usually on the far right. It would seem natural to have it on the left, then the first rcd next to it and run left to right?
@@cjmillsnun thanks for the reply.... I thought the busbar just ran the full length of the CU... 🙄😂 Edit....Just runnin it through me head... a common busbar would tie the 2 RCDs together in parallel...not what we want... 😏 Also... if a SPD was installed I assume you would have to go with RCBOs (or get a longer CU) ....?
I have added and edition the subtitles for this video - sadly this is not the case for all my videos but I am working on the more popular ones. Hope this helps Gaz

Great videos as always. Thanks for passing the knowledge to others specially youngesters.
One small suggestion . It will be a good practice ( safety wise)to tape around the cables that has been striped off and earth sleeving put on.
Tape is not a good idea, in warm weather it becomes sticky and comes off. A rubber sleeve is looks better and does not go sticky like tape.
I would have seen the spare fuse ways and split the rings into two radials and run them through 20amp MCBs. so that the 2.5mm cable is within maximum tolerance .

Edit....Just runnin it through me head... a common busbar would tie the 2 RCDs together in parallel...not what we want... 😏
Also... if a SPD was installed I assume you would have to go with RCBOs (or get a longer CU) ....?
Too good
👍
For those who are hard of hearing, could you please turn on closed caption?
I have added and edition the subtitles for this video - sadly this is not the case for all my videos but I am working on the more popular ones. Hope this helps Gaz
Great video, love your youtube channel!
Q; Do you have a video on diversity of the circuits?
Thanks
Gusman hi thanks for the positive feedback... sadly not at the moment 👍
Why exactly do you need to turn off the trips individually, why not just press the two yellow RCD's to achieve the same result.
Brown and Blue was a poor choice by who ever thought that up. In AU, we use Black for Neutral and Red for Active.
SPD - super priced device 😁
£40 or less
@@GSHElectrical question: how about if i need to install new shower circuit only , but there is no spd . Can i issue EIC then Or i have to install spd anyway ? There is no wylex spd which would fit in to 17th edition CCU (
Just wondering if anyone has heard of New Trades Career, formally known as green 360 ltd I think, they offer courses based around distance learning and then u go into practical centres after completion of certain modules , they are supposed to allow you to study whilst working full time , has anyone heard of them or got qualified doing so ? Many thanks !!
Hi. I always worry about course like the one stated. Thanks for the message Gaz 👍
@@GSHElectrical Hi. Thanks for the reply , may I ask why? Are they not legitimate? or do they just give you a qualification without the necessary skills to be able to work in the industry? Really enjoy all your videos by the way 👍
