Hi guys. Question pertaining to a step down transformer, and how you would wire it into an air compressor control for operation in conjunction with the air compressor.
I have a 5hp 208v 3ph Dresser air compressor. I run it off a dedicated 20A circuit(4 wires, 3ph + ground). I run a refrigerated drier after the compressor, which I currently plug in manually. I am also looking to put an auto drain on the compressor to help with condensation accumulating.
My goal is to flip one switch and turn everything on at once. Keep it idiot proof. The motor starter is obviously controlled by the pressure switch, so I could just put a double pole switch in series with the pressure switch.
Long winded, but do I need a transformer to step down from 208-120, because its definitely not up to code to go line - ground for the 110 circuit. Nor do I think its appropriate to pull another wire through the pipe for neutral, since it would be on a three pole breaker.
The easy answer would be run a dedicated circuit for the auxiliaries and put it into the double pole switch, but I dont have any more room in the panel to fit another circuit.
Any input appreciated.
