25mm swa armour for cpc Discussion Thread25mm swa armour for cpc Electrical Advice
Hi all,
Just planning a sub main to an outbuilding .
It will be 80 metre run, buried direct on a 63amp fuse .
So I am thinking of running 25mm swa but just been doing my calcs on whether I can use armour as Cpc. The outbuilding is going to be TT so no need of a bonding conductor on the submain.
After doing calcs in 2 core swa I get
99/51 x16 = 31.02
What I cannot find is csa of 25mm armoured to see if it is big enough .
If anyone could give me the answer it would be most appreciated
