Peak current refers to the maximum load current of one or more electrical devices over a duration of approximately ( ). A.1s B.5s C.15s D.30s The answer is A
Peak current refers to the maximum load current of one or more electrical devices, which lasts for about (A) seconds.
Answer: A. Peak current refers to the maximum load current experienced by one or more electrical devices for a short period of 1–2 seconds; it generally occurs during the startup of motors. Peak current is mainly used to calculate voltage fluctuations, select fuses and low-voltage circuit breakers, set relay protection devices, and verify the self-starting conditions of motors.
