I noticed the circuit that feeds my double oven is split at a junction box to wire both the oven and a former range top. The wire to the junction box is SER aluminum with a 50amp breaker.
At the junction box the wire is split to two smaller wires (one to the oven, one to the old range top with the wires capped). The wire is brown, solid and unmarked. It looks like 8 gauge.
I'm sure this is not safe. I would like to reduce the breaker size to match the brown wire and remove the unused brown wire from the junction box.
The double oven is marked 120/240 - 7000 watts. I believe that requires a a dbl 40amp.
I just want to verify that I should change the dbl 50amp to a 40amp to match the wire and that 40amp is correct for 120/240@7000watts. I will verify the brown wire is 8 gauge.
Here are a few pictures of the junction box with wires: http://66.232.129.14/o/oven1.jpghttp://66.232.129.14/o/oven2.jpghttp://66.232.129.14/o/oven3.jpg
