WebA 15A breaker is supposed to trip when the current flowing through the 14AWG wire exceeds 15 amps. But if things go wrong and the 15A breaker fails to respond, the 14AWG cable will overheat, starting a fire. This is where 12AWG shines. It can withstand more current than 14AWG without overheating. WebBreaker size must be rated for a minimum of 125% of the full-load current of the motor it is protecting, rounded up to the next standard breaker size. For example, the full-load current of a 5 HP motor at 460V is 7.6 Amps. The breaker must be sized for 7.6 * 1.25 = 10 Amps. Therefore, it is good practice to size the breaker at 15 Amps. reflective boys coats
