Good morning All,
Ive been asked to work out the potential volt drop on 12 metres of 10mm x 7 core SWA powering a 45kW (60hp) motor.
Just to check my findings as below, please could someone confirm whether I have done it right.
45kW - 80amp FLC
as using Star Delta Starter
multiply by 0.58 = 46.4 amps
10mm x 7 core SWA has acarrying capacity of 58 amps per phase.
The voltage drop I believe is 4.0mV per metre multiply by 12 metres = 48mV which I also believe to be around 0.06 of an amp.
Best regards
Simon
