I embarrassed that don't remember this but swallowing some pride is sometime good for a person. I am wiring a 3 phase in-line water heater and the manufacturer lists the current draw at 177A. at 480 volts, (144kw). Would that be per phase rating or would that be just the total. I was thinking it was just the total and i needed to calculate the phase current at 48kw/(480v x square root of 3)=58A. Unfortunately, I've started to doubt myself. Thanks for the help.
