I'm an American living in the US,& I just acquired a used Gaggenau oven designed to operate on 220-240v AC. My outlet is 120v AC, so, obviously, that not going to work for this oven. I have two distinct choices now, as I see it:
A: Have the breaker-panel circuit AND the associated AC outlet rewired to support 220v, which is complicated by the fact that I already have a 120v stove plugged into that two receptacle outlet
B: not change the wiring at all, but, instead, plug the oven into an external 120-220v STEP-UP transformer
/converter of the sort used to make many European appliances work in the US.
It seems to me that choice B might be less expensive, since most electricians in my area charge near $300 to do even minor work like that, and a good step-up converter like that can be bought for less than $100.
The kicker is that my Gaggenau oven has no AC power cord with a European-style 220v plug on it, just raw, heavy-gauge copper wires that are obviously meant to be connected DIRECTLY to a 220v circuit, rather than be plugged into it.
So, my question is, which of the above scenarios seems the best and most cost-effective solution to make this 220v oven work in my 120v home, while still retaining the ability to keep my 120v stove plugged into that outlet, and second, is it possible, and not too difficult, to install a 220v power cord and euro style plug on this oven IN PLACE OF the raw, unterminated wiring now coming out the back of it?
