I purchased a 10 HP, 3-phase Ingersoll T30 the other day that was unwired. I have attempted to wire the Furnas Size 2 motor starter and pressure switch back up to the best of my ability. I have 3-phase power coming from my RPC (American Rotary AD20) and have ran a circuit for the compressor (10AWG, 60A).
I am having an issue starting the compressor. I'm getting good power to L1,L2,L3. When I turn the switch to 'ON' the contactors chatter very loudly. I can manually push the contactors in and the motor starts and spins just fine. When I release, the contactors do not hold and the motor powers down..
I will upload pictures to this thread to help with assisting me, thanks!
I have a 10HP lathe running off of this RPC also so I do not believe that is the problem.
