Conductors to a single motor ... size = 22A x 1.25 = 27.50A A quick check of Table 310.15(B)(16) reveals that a 10 AWG conductor is rated 35A at 75°C. The branch circuit short circuit and ground fault ...

Let’s run through an example problem to show you how this is done. What size conductor and inverse time circuit breaker are required for a 2-hp, 230V, single-phase motor with 75°C terminals (Figure)?
