connecting to existing lighting circuit

[siras]

Greetings, i have a question about a kitchen install. The previous kitchen had under counter lights switched from a normal light switch, i have checked the fuse board and it's not on the rcd side, they will connect new under counter lights to this circuit will it have to be put on the rcd side after instal... hope you can help

YES and NO....!

Yes it Needs RCD as you have modified the circuit but NO it dont need to move position in the CU as you can fit a RCBO

but does just replacing the fittings count as modifying the circuit.? RCBO good , though.

Thanks Steve the rcbo, are they compatable with haeger boards i.e can they be retro fitted...?

It would only need RCD if any new wiring was installed in a wall or in a bathroom, unless wiring in wall was otherwise protected. You don't need to bring old installation up to 17th ed unless your new work requires it.

as long as you can get it in, shouldn't be a problem

i agree with that. IMO, just changing fittings does not constitute a circuit modification
