no earth in lighting circuit

[mcm]

changed a consumer unit today from old wylex board to new 17th dual rcd, when i was stripping out i noticed no earth in the lights cable. what would be the best way around this re-wire or can you fit class 2 fittings and switches.

thanks

Class 2 switches and luminaires / pendants label C.U. warning no lighting CPC

or you can leave as is shove sticker on saying no earth and issue Danger notice with recomendation to remove metal stuff and change to plastic!

The best way would've been to realise this before the CU change tbh.

Forgive me as I have not been involved in domestic electrical wiring for sometime and not yet upto 17th edition so here is a question - if my upstairs lighting has no earth would protecting the circuit with an RCBO mean that it would meet 17th Edition regs??

It would have overcurrent protection and earth leakage protection - wouldnt it?

the rcbo i use have no earth fly lead so yes dont see why not but wont be to 17th regs

No. Because there is no cpc.
