Discuss TT system, RCD or RCBO in the Electrical Forum area at ElectriciansForums.net

Welcome to ElectriciansForums.net - The American Electrical Advice Forum
Head straight to the main forums to chat by click here:  American Electrical Advice Forum

At the risk of asking a silly question could someone advise me on the following:

Client has a TT system with only half the circuits covered by an RCD, they want a light adding on a light circuit thats currently not covered by the rcd.

Now with half circuits not going to meet the disconnection times if I work on just the lighting circuit would I still have to cover all the circuits that haven't got an RCD with a new RCD or am I allowed to cover just the lighting circuit with an RCBO because that's the circuit i'l be working on?

Because of the results when testing I'm thinking i'm going to have to cover all the circuits but I'm just wanting to check the RCBO route incase the IR is low (old wiring) and nuisance tripping could occur (I know the clients won't be wanting to pay extra if I have to start going digging).

Thanks in advance
