I have a 40 gallon Vulcan kettle that I'm converting to single phase for my summer rig. One fellow that did this states its as easy as changing the wiring to the elements in parallel instead of series. Since I will be feeding in 2 hots instead of three, I'm to disregard the third leg on the contactor. That's all fine, my question I have is if it is rated 24 KW on 3 phase, would it be the same amp draw on single phase? I'm thinking it would be higher? Its currently 208v and I would be feeding 230v.
