The 3 Best Ways to Determine Amperage of Circuit Breaker
WebMay 1, 1996 · 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.
