URGENT F.A.O Sparkys / Engineers
Need someone to do a cable calc (sub main) for me quickly if poss havent got amtech or anything installed on the laptop or my regs book or barbour log in details! Very well prepared today!!
Sub main from section board will be installed on ladder (touching). Protective device is a 315A HRC, XLPE/SWA at a distance of 95m. Just class the load as a fixed load rated at 250A TPN.
Dont worry about the earthing the end user has stipulations of 50% of the conductor size, very old school!
Cheers in advance guys!
