planning to instal lights & sockets into garage thru a c.u. have got a length of 2.5mm2 cable, will this do from main fuse box to c.u.? or is it to thin. out of interest what difference would it make?
If you go to http://www2.theiet.org/Publish/WireRegs ... /index.cfm and issue 16 Electrical installations outdoors: a supply to a detached outbuilding it details all you need.
If you need any clarification please ask.
