Consumer unit - RCD mainswtich - how many circuits does it cover?

[Taylortwocities]

@jero if you carefully remove the front cover of the CU and post a photo of the innerds, then we can clear up the mystery.

Why is the OP concerned? Not that they shouldn't be, but is there a major reason behind it?

Each device is numbered running upwards away from the switch it's connected to.

My instant observation was 1-5 are on a grey background and 6-8 are white

That was also my first observation, and I nearly made that comment myself - but I then realised that the important issue was that the labelling of 6-8 had been changed, not what colour background the labels had. The original 6-8 markings had clearly been 'reversed' in order by over-sticking new labels (with a white background). However, as everyone is saying, that very strongly suggests that it's 'those three circuits that are RCD-protected.

Precisely. Which is why it's incredibly obvious that the ones on the white label are the ones connected to the RCCB. Not sure why most here are pretending that it is some sort of impossible guess. It's extremely obvious.

Hi All,

Here is a picture of our consumer unit. Would you think the RCD covers all circuits or only a subset?
The RCD says ln=63A, while the mains is 100A.

Thank you!

OP - why are you asking this ?

OP - why are you asking this ?

Particularly giventhat if he was so keen to know, this

Press the yellow button to test the RCD - as you are supposed to every few months - to switch off the RCD and (if it works) find out what circuits don't work.

would have only taken a few minutes do do.

Mind you - he's been asking random questions about his CU for a year now.

Well, if it were my CU, I'd like to know which of the circuits in my installation were RCD-protected (not the least in case the answer suggested that some upgrading/updating would be desirable), wouldn't you?

Hi All,
I attached pictures of the fuse board from our 2 bedroom flat.
How would an EICR assess this? What category would be assigned to it?
The fuse board is working well, we have not had any issues with it.
Thanks!

Quoted from an earlier thread

Why do some posters do this?

Ask questions and just provide as much info add possible is the best approach imho

Back to the OP - it’s impossible to say what the outcome of an EICR would be but my advice to you is get the CU replaced as that one is obsolete and over 20 years old

OMG panic stations...




























































































requires replacing because it's over 20 years old?

Hi Everyone, thank you for the replies, they were really useful, and apologies for not coming back with feedback earlier.

The reason I asked because our landlord's agent did an EICR a year ago (yes, June 2024..) and the agent and its contractors wanted to do works in the flat without sharing the report or providing an explanation why they were needed. It is a personal preference, but I'd rather not have unnecessary work done while we live and pay for the flat. It would not be the first time the agent 'found' work for their affiliated contractors. The EICR was prepared by the same company that would do the fix.

We have now finally received the report which stated several C2 categories:
1) lack of RCD on circuit 1-5
2) lack of RCD on bathroom lights
3) CU made of combustible material

After some research, to me it does not seem obvious that these should be C2.


Would you agree with these categories?

 

[Murdochcat]

So an unsatisfactory EICR over 1 year ago

That’s not ideal either

Why are you reluctant to let the landlord act

You're not alone. I think many would question whether any of those things [particularly (3) ] should be C2s.

However, what I don't understand is that if an EICR was undertaken a year ago on behalf of the landlord, and that(rightly or wrongly) that EICR reported three C2s, that put the landlord under a legal obligation to have those C2s 'remedied' within 28 days. Why did he/she not do that?
