Product review (5 stars): Good morning. Sorry to hear your electrician couldn't figure ...
Received this item and manual has no schematic for the proper way to hook up this unit.  Had an electrician look at it last night who has 40 years experience and was not sure how to hook up due to the touch sensitive control top.  Emailed the seller and received this response:
Good morning.  Sorry to hear your electrician couldn't figure it out.  This is 220V cooktop and you have to feed 2(110V each) hot wires to it.
Black is 110V
White is 110V
Green is ground.
Best regards, K&H team
Had this wired up in a few minutes and it works perfect.
