Hey guys. I have a single phase 240v 2HP motor so the FLA is 12A as per Table 45. It has no problem starting on a 2 pole 15a circuit breaker but I need overload protection according to rule 28-308 (a) because its more than 1 HP. I am just having a hard time explaining to the customer why they need the overload protection when the breaker is only 15a. I could understand needing it if I had to put in a larger breaker for the inrush current but its ok on a 15 amp. I was reading about the breakers inverse time characteristics so if it had a small overload the breaker wouldn't trip and that would damage the motor? Any help would be great. Thanks.
