Can you sign off any work with a 30ma RCD.

Hi, my question is. If I have an old wylex consumer unit with NB type 2 breakers (not 60898). Or let's say any CU for that matter. If it's protected by a 30ma RCD, will that pass the cert?. Or for example will the use of old mcbs not be up to standard. Thanks

Are you doing a Eicr test?.

No, new ring has been wired to a new extension at the back of the house and just needs an EIC.

The installation needs to be in a safe condition to extend.
Any new circuits or alterations need to meet latest regulations.
It's theoretically possible to comply using a rewireable board.

Numerous questions come to mind, for for starters:
Where is the RCD installed, between meter tails and consumer unit, or at the start of the new circuit?
Has a surge protection device been installed?
Is the lighting in the extension RCD protected?
Is there a bath or shower room in the new extension?

Thanks for the reply This is the puppy, RCD protecting all circuits in the house. Everything past this consumer unit meets regs. If RCD is testing fine and all other tests are fine. Would this be acceptable to sign off, or would most go down the consumer unit change route?

I'd be concerned about the 30A breaker allegedly for upstairs lights? What size is the cable on that circuit?

Good spot, but that's a ring circuit.. needs to be reblabled. Assume every circuit has the correct rating for each cable it's supplying.

I would suggest that it was upgraded and inform the client that any future work would likely need an upgrade.

I agree an upgrade would be best in this situation. Just want to know, would this be okay to sign off if the customer really didn't want an upgrade
