Consumer Unit - RCBO Upgrade??

[Martin McLaughlin]

Hi all,

Looking some electrical advise. I've been told by an electrician that I need to install 5 Nr RCBO's to this consumer unit. Is this correct or is the current set up ok? He has provided me with a condition report stating a 'C2' on the cables concealed in walls. If an upgrade is required will it take 5 NR RCBO's or are RCD's sufficient?

C3 for cables buried less than 50mm in the building fabric.

Also, although someone will probably prove me wrong, id be shocked if you can even get an RCBO for that board.

Like to know where they are going to source compatible rcbos for that board.

Without seeing the installation or the whole report its not easy to comment on the coding, usually this would be a C3 but there may be other factors to consider.

Whilst it might be possible to bodge a single RCD in instead of fitting RCBO's it is not advisable and could cause more problems.

On etching that needs fixing very urgently is the missing blanks from the front of that board.

Someone has stolen your blanking plate mate , or has it always been missing ?

Did he code the plastic board?

Looks like a commercial site, DB GLP (Gr Fl Ltg & Pwr).

The NAPIT codebreakers book advises a C2 for no rcd protection of cables buried less than 50mm in wall. Like others, I would advise C3.

Found one of these Ashley & Rock DBs at a house in Creggan in Derry a while back. I believe they were bought out by Hager quite a number of years ago.

I'm pretty confident you won't find any devices for it. I mounted a separate DB for work I did.

I took it to be General Lighting & Power.

You can. It's old Ashley Rock supasafe that was bought by Hager. They based their range on this breaker pattern and it has not changed. I have had confirmation from them before that they fit and Hager give their blessing for this marriage.

The older supasafe with the red writing however are not compatible.

Yes quite correct.

how come theres a main switch labelled "main switch" and also an RCD labelled "main switch"?

It genuinely amazes me how many people come on here asking questions who don't trust their electricians. Some cases they do have a point bit rarely. Still amazes me though waiting on the day a job I quote appears here

^^ given you are in Belfast too, couldn’t you go and have a look and advise the op?

I think the board also looks like an old seimens board I’ve had trouble looking for an RCBO to fit.
Hager does fit nicely but customer is going for a board change instead
