Hi Everyone. I have a question on the correct equation to calculate how much current runs through a phase to phase configuration.
a 4000W heater is connected to phase A and B on a 120/208V 3 phase panelboard. To size the breaker, should I be using 4000/(SQRT3*208) or 4000/(208) to determine the current through each phase?
Single phase and three phase calculations I understand, but this two wire three phase configuration is a bit confusing..:blink:
