[bushynut]

Well I'm undertaking my revision for my exams in june and have come accross a problem

I'v lost my notes on how to do cable calcs for 3 phase motors, so if anyone can tell me is there anything different to the cable calcs other than the normal sequence that i should no of?

As in the pf where does that come into it?

thanks in advance
