So here is my dilemma. I have Whirlpool wall oven /microwave unit that is new and cannot be returned, and am moving into a new house. The unit requires 40 amp 220V with an 8 gauge cord. The existing outlets are 30 amp 220V with 10 gauge and 20 amp 120V with 12 gauge.
So far my ideas are in the order of current preferences:
(1) draw a new 8 gauge line from the panel to the location of the oven. This would require opening up dry-walls and drilling holes. There are about 25 feet of three walls that would be impacted and we would have to drill holes in studs for about 15 ft.
(2) sell the unit (again it's new, but not returnable) and buy 2 separate ones that matches the power of the two existing outlets, which would mean they would not be integrated and instead of two ovens I would be down to one oven and one microwave. I rarely use two ovens (like once every second year), but I like that it has an integrated control. Any recommendations for a matching set with similar features in case I go down that route?
(3) It looks like the baking, broiling and convection units are the only ones using 220V. The diagram shows 220V (l2 on diagrams) and 120V (l1 on diagrams). Do I read that right? IF (and I do not know that) the only situation that it actually draws 40 amp is when both ovens run at the same time. Is there a way to disable the smaller oven in the microwave / oven unit and only run 30 amps (we could hook it up and measure it).
Or other suggestions I had not thought about?
