monkeyhead said:480VAC 3 phase motors (most < 3 hp) - 10 or 12 AWG Black (some of our vendor installs use Brn/Org/Yel of the same AWG rating)
120VAC controls - 14 AWG red
120VAC nuetrals - 14 AWG white
24VDC controls - 16 AWG blue
Grounding - Equivelant AWG of above mentioned with Green wire
This is pretty common on our customer's specifications though the its 16awg for 120vac controls and neutrals (rare for control wiring, mostly retool of older panels).
