You are required by the NEC (National Electrical Code) to run a circuit from a two pole circuit breaker that serves only that motor load. You will run then, two hots and a ground. Depending on your local codes, this can be in NMC, MC or raceway AKA flex or pipe.

Depending on the circuit length, this might be in #10 or #8 depending on the distance and RLA, running load amps. THe back of the NEC has tables for calculating voltage drop, but I'm sure there are on-line calculators for you to figure this out.

DO NO SKIMP ON THE WIRE SIZE. This will cause a fire.
