What gauge of wire to use on 203v

[C.Michael]

Hi everyone..I am running some big motors on my table that is still being built..1200oz/in from keling..The power source is 72 volts 20amps(keling)..so what gauge of wire should be used to wire up each of the 203v..also when it comes to the 3 wire leads from the BOB to the 203v driver,can I twist them to make a tighter cleaner wire job..I tryed taking the ends of the 3 wires and twisting them using a cordless drill..works great but is that the thing to do..maybe causing some sort of cross over problem??..Mike

I can't tell you want you should use.... I've only done one controller, I did use g203v's.
This is what I used:
22g wire between bob and drive
18g wire between drive and motors
14g wire between power supply and drive (I had a hard time getting 14g into terminals) I'll use 16g or 18g if I decide to add a cap to the drive.

Power supply, or anything power related, nothing less than 18ga awg, steppers, bob etc 22 ga awg. I went with whatever my motors were wired with all the way to the BOB.
