don't forget that that figure is just a relatively conservative estimate of the 3 phase PFC but it is *NOT* a worst case.ricicle said:Don't forget to double your SP PFC for worst case scenario 3 phase PFC (if your working on 3 phase)

in particular a bad neutral could easilly make your single phase PFC very low but would have no affect whatsoever on the phase-phase PFC.
