Customer Question

I recently purchased an air compressor with 7 1/2 hp, 230v, single phase motor that also has a magnetic starter. The motor tag lists volts 208-230 and amps 33.30-31.30. Will 4/3 with ground wired to 14-60 terminals be adequate? What amperage breaker do you recommend?

4/3 is overkill unless you already have it. 4/2G would do on a 60 amp breaker. Just checking, did you get the compressor working? Do you have any other questions? Thanks
