Hi,
As Im currently doing out the lounge, I have chance to update the wiring (house wiring is 1969)
Ive already split the downstairs ring mains which was original one complete ring (including kitchen) and now have kitchen, upper and lower rings separate.
Unless told otherwise I dont think the lighting wiring needs alot of updating (although again I have split this to upper and lower rings), but the one thing it doesn't have is any earth wiring for the lighting. As the downstairs only has 3 light switches in total, and two of them are back to back with each other (the lounge and the hall), I thought it would be a good time to put in earth wiring down to each of the switches (and the light fittings).
My question is, can you just tap on to the mains ring earthing, or does it need to be a completely separate route from the CU?
Many thanks
