Sizing a Circuit Breaker EC&M

WebbMinimum Circuit Breaker Size = 12.5A × 1.25 = 15.63 Amps. We can’t use a 15A breaker because the breaker ampacity should be at least 15.63A. The next breaker size is 20 … WebbWe have to account for the 80% breaker rule. This means that these 12.5 amps should represent 80% of the breaker amps. To calculate the size of the circuit breaker needed, we have to multiply the amp draw by 1.25 factor like this: Minimum Circuit Breaker Size = 12.5A × 1.25 = 15.63 Amps. editing landscape phlearn

Sizing A Circuit Breaker: Breaker Size Calculator + Amp Chart

Webb1 maj 1996 · CB Sizing Examples The following are examples of sizing rules. Example 1: 50A continuous load and 125A noncontinuous load. OCPD = 100% noncontinuous load + 125% continuous load = (1.00 x 125A) + (1.25 x 50A) = 187.5A Therefore, a 200A OCPD is needed. If a 100%-rated CB is chosen, a 175A rating (125A + 50A) is acceptable.
