Hi again all,
I am currently refurbing/rewiring an old cottage/outbuildings/new extension etc etc.
The meter box is outside and i want our CU in a cupboard 15m away.
It is a TT system and the rod is below the meter box outside.
I have read a few historic threads and am thinking the Click 80amp sw/f is best option back to back with meter (in a small cupbd dead handy)
Then either 25mm tails or armoured through building to CU (noticed divided opinions on tails 15m)
Firstly.
Do I still need a 100ma TD RCD to cover the tails/armd (they will be in floor space and 1 safe zone rising from CU) As in 16th edition.
Secondly where do I put the MET ie do I take 16mm G/Y from rod to near CU or can input/output it from 80a SW/F (prefer to take bonding back to CU if poss.)
Sorry for long story
