I converted one of my compressors to 240v.
Instead of using a normal 2pole 3,600rpm air compressor motor I found a 4 pole 1,800rpm motor.
I have found that high speed 2 pole motors typically have a momentary start up in rush of 4 times shut off current.
This motor is hitting double shut off amps on startup.
This is normal starting with the belt on the compressor.
4 pole motors have a momentary inrush of 2 or 3 times shut off current.
