Understanding your Consumer Unit (Fuse Board) Overcurrent & RCD Protection plus Isolation Features

Students training aid on the different elements of a U.K. consumer unit (distribution boards or fuse board or fuse box). This videos talks about switching for mechanical maintenance and emergency switching. The different types of circuit breakers B, C and D as well as overcurrent and short circuit protection. The video breaks down the elements of the consumers unit and shows best practice with things such as identifying of conductors and the need for earth fault protection via a dual RCD (RCCB) rated at 30mA or less.

Not just for students. Even for the experienced, it's always good to go back to basics and keep up with CPD.

Could you imagine being taught by this guy!
Awesome video, i know its older but im watching as much as i can right now, old and new.
Im 40 years old and im going into training this coming september to become an electrician.
I hope i get a teacher half as good as this guy

As an electrical enthusiast, this has been extremely interesting to me. As a result, you've earned yourself a subscriber :) A huge thanks!!

Excellent video, straightforward and well presented, very engaging.

[danielhammond]

You are really a good tutor and I will be happy to be your student.

[montystelevision]

I've really grown to love this channel.

[CO]

Brilliant tutorial, many thanks indeed

[OluwafemiAderanti]

Fantastic video!!! concise, explanatory and straight to the point. i think i need to get to the

[athurbraga]

Yes yes yes after 20 years working for other ppl thank to this video i decide to become electrician deposit paid waiting to start and cannot wait You made this clear and simple. One question though what is electricity and how it is generated on atomic level ? sorry if this question looks stupid

[scott]

linked main switch it makes so much sense now lol!

[shilks]

If using RCD's (Better to use RCBO's) then its a good idea to have the Oven isolator with the spare socket on the opposite RCD to the Downstairs Sockets - you can then at least have a cup of tea why you scratch your head wondering what has tripped the other RCD.

I am looking to instal a BWT WT555 water softener, Can this be 500mm away from my Consumer unit, I could not find location restriction for consumer units online, thanks

[animarkzero]

I needed to use a C-Type Fuse for my homeoffice, as there are a lot of switching power supplies!
So when I turned on my multiple socket outlet sometimes it would trip the formerly installed B-Type Fuse.
FYI: I live in Austria, so we have no ring circuits and fused plugs. Circuits here are fused much lower(10A-16A typ. 13A)

[taktak]

Great stuff very clear and understandable

[jchattey]

Great video, like the cable markers - not seen them used before, suits my OCD side :)

[venosjones]

I was pay 7800£ for too study in London for a next 18 month is really good too learn something before too start too have some knowledge from advance

nice video, I have two consumer units that receive electricity through separate cables from the electric meter. One unit with RCD replaced the old fuse units and there's another small consumer unit with SCD; one supplies electricity to the shed, another one to the EVC charger, and the last one to the shower. Last night, when we tried to charge the car, it didn't charge because there was no power supply. Upon checking the small consumer unit, we found that it was not supplying any electricity, even though all power switches were still turned on but consumer unit gets power. I'm not sure about the difference between RCD and SCD; maybe a video could help explain this. The SCD says that if it shows red, then it needs to be replaced, but I checked and it's still showing green. Can you please tell me what could be wrong with the small consumer unit? Thanks.

Hello Sir, initially really I'm very thankful of you for your very helpful video series, could you please answer these questions, about RCD and RCBO, it seems that RCBO is better than RCD because RCBO does somehow operation and in this way "save life of people" and also protect the devices such as TV and washing machines and so on, yes ?? So what is the difference between RCD and RCBO?? which one of them for home is better and most suitable ? each ones RCBO for TV and washing machine is needed separately ? each one should has which specifications/ amperage ? each RCBO can cover how many devices ? sorry a lot of questions !! I am contacting from Kiev in Ukraine and by answering my questions you will solve a lot of problems for me and at the same time it is a very big favor, Your fan, your supporter, Afshin Heydari
