New Consumer Unit Needed?

[Colin33]

I've been asked to do some work on a domestic installation. However, it seems all but the shower and garage supply are not RCD protected. Does anyone know if single module rcbo's are available for this Merlin Gerin board or is it gonna have to be changed?

No idea why the garage has an RCD at this end, but it can stay put. I would replace the 6 mcb's in use with rcbos. Only need to work on /add to two circuits but why not do the job properly and make sure all circuits are protected?

There is no requirement to add additional rcd protection to circuits you are not working on.

Sorry misunderstood, thought you were saying the shower and garage needed RCD protection.
So your intention is to upgrade the installation to the 17th?

I have to add some sockets and lights, so certainly want to make sure all is rcd protected. As for upgrading the whole installation, it's mainly old coloured wiring and probably missing a cpc on some of the lighting circuits too but a rewire is not an option at this time...

As I thought westward, but I'd be happier doing so if the client is happy... it doesn't make any sense to me not to.
