[QUOTE="Dairyspark, post: 536843, member: 19743"] Each phase has 3 x 2kw elements attached to it so in my mind it was simple P=I/V I = P/V 6000/230 = 26.08A Which then let to me thinking each phase passing it’s current back through a common neutral which left me with 78.26A to return down the neutral line, but now that it all works out as a balanced 3 phase load there is no neutral current. However does that mean I’d say one of the elements sections (2kw) fails will that then unbalance the load on all three elements and cause the high neutral current or only on one of the elements and the other 2 are still balanced?……am I making sense?
