air compressor motor


You have a dedicated 120 V / 20 amp circuit and a 120/240 volt motor. Convert the circuit and the motor to 240. The motor will be more efficient and draw half the amps. Replace the breaker with a 2 pole and replace the receptacle and plug (less than $40 material).

For example, the older Square D breakers had a pretty high magnetic trip, the newer ones are very likely the lowest in the industry.

If it's an arc-fault, it'll absolutely trip with a motor that size.

Some (if not all) manufacturers make a 'high magnetic' version of their standard breakers; this would likely solve the OPs problem.

I agree with the others, if it's a dedicated circuit, and there's room in the panel, I'd highly recommend changing it to 240.
