how to size a circuit breaker hunker

the "size" of a circuit breaker is the maximum current that can pass through the breaker without tripping the circuit and causing a loss of power. in other words the breaker controlling a circuit should be 125 percent of the continuous load maximum current expected to last for three hours or more and 100 percent of the non-continuous load shorter bursts of power such as that needed to start up .

sizing a circuit breaker electrical construction

cb sizing examples. ocpd = noncontinuous load 125% continuous load = 1.00 x 30a 1.25 x 16a = 50a therefore a 50a device can be selected. although 100%-rated devices typically are not available in sizes this small the permitted rating would still be 50a 16a 30a = 46a; rounded up to 50a .
