Hi it's Shaneo here, I'm an electrical contractor on the South Coast and would appreciate some advice on what size electrical cable to use from the Eskom box to a single phase 63A DB board for a domestic installation (4 bedroom house). The distance from the box to the house is 160m and the cable will be buried. I've been looking at the voltage drop tables but not 100% sure if I'm understanding it correctly. Not sure whether to go with 16mm ECC or 25mm ECC, Thanks.
