Hi this is my first time on this forum so take it easy please but I'm after a little bit of advice... I wonder if someone can help me calculate the voltage drop of an install that is in the process... I will give you as much info as possible, any help would be greatly appreciated...
.400a main intake head has been installed with a 400a isolator (3 phase 400v)
.Job is the install a sub main cable to feed an LV panel (400 supply)
.Sub main cable is SWA PVC 4core wired outside across a roof on perforated cable tray with a separate earth
.Cable run is 50m
I am trying to work out what size cable will be required and can't get to grips with the formula's, again any help would be appreciated.
Thanks Dan
