Yes we know that. So OP have you worked out your cable size.I do not insist they are the same. I insist that a TN-C-S is a TN-C but then seperated. A TN-C cannot be a TN-C-S.

Taking that the Ib is 60amps (k.m.f il install with bs1361 60amp fuse in it) distance of 80 metres will be 35mm swa having a volt drop of 6v. I believe this to be the correct size, correct me if im wrongYes we know that. So OP have you worked out your cable size.
2 core single phase 3%How many cores are in the cable and what %vd are you using.
Would you agree?How many cores are in the cable and what %vd are you using.
Il give you the scenario, stables in a field, e-on have been out and put a supply in a hut with a meter on and a one shot, main fuse is 80amps, the customer need a fuseboard putting in the barn, 75metres away, what size cable would i be looking at, ive done a calculation, 1 x swa cable 3 core, burried, ive use 80amp as the demand as this is the maximum at the origin and the cable size is coming back at 25mm. Is the right or is there some sort of diversity applied which would allow you todrop to 16mm. All that will be going in are sockets and light, quite a few to be fair but altimatley just wanted to get the armoures cable to the fuseboard and just questioning the size. Any help is appreciated
Figured this one out yet?Yeah im now thinking degrade the fuse rating in my isolator, going off topic how do this work in domestic when the heas is a 60amp but the mainswitch on a db is 100amp
we will be able to after brexit.Why are you not allowed to export the earth?
