Hi all
Just a quick one , got called out today problem with lighting circuit. A new split board fitted with an Rcbo for the lighting circuit. Insulation tested the circuit from the last lamp all ok. Then went to test from the switch , No earthing in the switch's .Yet all light fittings were earthed , checked in the attic to find a 1.5mm earth running from each fitting back to the board.Checked in BS7671 2008 unable to find anything . Does anybody have any idea's regarding this?

I was always taught to take the earth wire through to the switch (even if there was no earthing terminal there) and for expansion at a latter date, or for example the homeowner changes all the switches to chrome metal.

This is defo bad practice, but I am not sure where it is covered in the Regs?

As far as im aware this is acceptable providing a label has been fixed to the cu stating that no class I switches to be fitted due to lack of earth at the switch.

I have done this myself, as im sure you can appreciate, because most clients would not want their house ripped apart just to drop an earth wire to the switch.
