The cord reel was then wired to draw an overload current of _______ A, at rated voltage, on all conductors which normally carry current. The overload current was equal to 110 percent of the maximum current as limited by the [branch circuit breaker] [overcurrent protection device]. The [branch circuit breaker] [overcurrent protection device] was bypassed for this test.9 B8 V# H: s% F+ D) Z
