We have LED drivers with a rated inrush of 185 amps at 200 microseconds (.0002 seconds. We are trying to determine how many drivers we can place on a 20 amp, 120v circuit. The circuit breakers TCC curves start at .001 seconds. Also, the fuse TCC start at .01 seconds. What happens if the event is shorter then the published TCC curve and is off of the curve? Will the breaker or fuse trip or is the event short enough that the energy will not all the overcurrent protection device to trip?
