Hi there. My house needs re-wiring, and I'm planning to get this done (by a professional) in a year or two. In the meantime, I would like to put up a light fitting that needs an earth connection.
Problem is, my lighting circuits are not earthed.
Would it be safe / acceptable / hideously dangerous to put a JB into a nearby 13A ring main and take an earthing wire from that up to the ceiling rose? The house currently seems to have PME and all the earthing connections are commoned beside the main fuse. As an alternative, could I run an earth wire from the fuse commoning block up to the ceiling rose? Or are both alternatives no-go?
I am a (lapsed) electrical engineer, but have no training in house electrics, so I understand the general principles but not the details and I can carry out work to a competent standard. But some expert opinion would be most welcome.
