Hi all, i'm after some advise and thought this would be the best place to ask ?
I have a supply cable to an out building, currently in 16mm T&E and an underground copper water supply also in the out building. The pipe currently has no bonding.
I want to upgrade the cable to the out building. Would a 16mm 3 core SWA be suitable, using the 3rd core as a combined CPC and bonding conductor.
Main supply to house is overhead assumed to be TNS due to the supply cable being Split Concentric....
Thanks in advance
