I really thought that too. but its nice to get a second opinion. He will just have to put it up for sale and hope he gets his money back. You know how those great deals are you cant pass theme up. What do you think aboat it when the acual power is 248V between phases. this is commmon here in this area. and 124v to ground.
Thanks for the response Al. I just wish people would ask or that they know what there buying before they call and say come hook this up. Ive actually have seen the same 3phase lake pump 3 times, 2 times I came out to two differant homes to hook up sprinkler pump and the 3rd time i saw the pump in the local pawn shop. I wonder how many people have bought that same pump.
A cooktop that is rated 208V, and can be wired for 1 phase? That sounds like a strange animal. You might want to double check how it is actually wired just in case it can be adapted. If wired for single phase, what would its voltage requirement be, then?
I have seen some cooktops that say they work on either 208V or 240V, and list the same kW rating either way. I'm not sure how they accomplish that, but I suspect they may be running each element on 120 volts and don't really care what the phase angle is between the phases.
capt al: do you have a wiring diagram for 240V 4-wire delta (the customer probably does not have 240Y/139) via buck/boost to get 208V three phase? Or were you suggesting doing this only in single phase?
