HI All,
For some reason I've been unable to get a definitive answer about this simple question:
So when I have a generator operating in 3-Phase and I use the formula KW x 1000/E x PF x 1.73 to get amps, the answer would be per phase or leg, correct?
For Example: 40 KW x 1000 / 480v x .8pf x 1.73 = 40,000 / 664.32 = 60 Amps @ 480 volts
This means that ALL 3 phases would be capable of 60 amps at 480, correct?
I'm pretty sure that's the case but "pretty sure" doesn't cut it when your dealing with electricity. That'd be akin to telling a pilot you're "pretty sure" it's OK if they land in about ten minutes on our super-busy runway. Ha!:happysad:
Any answers would be appreciated. Even the Snarky ones...so long as they are correct.
Many Thanks,
Smatthew
