Actually, the two are pretty much identical in actual power capacity:

40A 400V 3ph ~ 48KW

Blink..blink...that would be 100 amps of 400 volts..wouldnt it?

you are short 60 amps somewhere...G

40A * 1.732 * 400v = 27712 (P=IE*1.732) since it is three phase.
200a * 1 * 240v = 48000 (P=IE*1) since it is three phase.


Did I get this right?

No; you've got the right numbers and wrong answer

You probably meant to say "single" instead of "three"
in the second line.

Looks right. but the 200 amp is "single phase"

"First Law of Leftist Debate
The more you present a leftist with factual evidence
that is counter to his preconceived world view and the
more difficult it becomes for him to refute it without
losing face the chance of him calling you a racist, bigot,
homophobe approaches infinity.

This is despite the thread you are in having not mentioned
race or sexual preference in any way that is relevant to
the subject." Grey Ghost
