400mm? have you ever pulled a 400mm 4c ,i,ve pulled 300mm 4c & singles upto 1000mm
but your talking high current way above the 120a that started this thread .My college days
are long gone but i still reckon 2x 70mm 4c will do it.
But back to the original thread it doesn,t give you a clue as to how the cables could be installed so you don,t know what the correct factor to apply so more info needed

yours benji


sorry 120a should read 200a but still reckon 2x704c

No no, i was just using the size as an example and showing to divide the CSA by two for the correct cable size.
