A. Branch-circuit overcurrent devices must have a rating of not less than 125% of the continuous loads, plus 100% of the noncontinuous loads [210.20(A)]. Note: See Sec. 210.19(A)(1) for branch-circuit ...

Generally, the Art. 210 requirements for branch circuits are prerequisites for applying requirements found elsewhere. This fact is exemplified by the overcurrent protection requirements [Sec. 210.20].

The usual way of preventing a small motor from drawing too much current is to install overcurrent protection in the form of a circuit breaker or some other kind of limiter. But installations that ...
