Hello,
I want to install a run of 6 mains (GU10) downlights into a previously unlit area. The downlight fitting instructions say that the lights are double insulated and must not be earthed. My question is what type of cable to use: the usual twin-core and earth (where the earth will not be used), or is just 2-core cable OK (if there is such a thing as 2-core cable, or is it always flex?). It is not likely that the lights would be changed to some other type, so is an earth wire necessary?
Thanks in advance for any advice.
