I remember someone asked if I could post what I found when I opening the
boxes up and checked the wiring.
Before I started I figured out the counter top stove is on the same circuit.
2 single pole
║ 12 30amp/30amp 16
║ 12 30amp/30amp ??
╚═════════[fuse box]═════════[Stove Top]
I doubt the line drawing will be legible, so I will try to explain.
Both single pole breakers were 30amp (one of the switches was chipped
hence why my dad read 50amp on one.
The cable leaving the box was 6 gauge 4 wire.
when I opened the box under the oven I found 2 30 amp fuses and a 15 amp
fuse. The wires coming into the box were 12 gauge 4 wire so I knew there
had to be a box in the basement under the drop ceiling.
The old oven had 5 wires coming out and used the 15 amp fuse to protect
the clock etc. The new oven only has 4 wires.
The box under the drop ceiling split the 6 gauge into 2 12 gauge runs
one to the box under the oven and one under the stove top.
I did not check the gauge of the wire into the stove top but the wire
that came with the oven is 16 gauge.
I replaced the two single 30amp breakers with a double pole 40amp.
I left the existing box in place and connected the new oven to the 30amp
fuses and took out the 15amp fuse.
