Wiring wall oven
I am in the middle of a kitchen remodel and we are replacing a combo wall oven/ micro unit with a new wall oven/ micro that connects separately. The existing circuit that supplied the old setup was on a 50 amp breaker with 10/3 or 8/3 stranded wire. Way more that the new wall oven needs. Can I bump the breaker down to a 30 amp and use the existing wire? or do I also have to reuduce wire size?
