I have a wall oven and a microwave oven, connected to 30A and 20A breakers respectively, and both are 240V.
Now I'm thinking of replacing it with another double-oven model that runs a single wire powering both ovens. According to the specs, the maximum possible power is 7800W.
The official website says that 32.5A is the maximum load. I assume that it should require a 40A breaker. However, the installation manual says to use a 50A breaker.
My questions are:
- Is it safe if I combine the wires that are currently connected to the oven (30A) and the microwave oven (20A) to the new double oven?
- I assume that the diameter of the wires shouldn't be the problem, because they're joined at the very end of the circuit.
- According to all references I can find, a 40A breaker is sufficient to power 7800W at 240V. Can I assume this, or do I need to strictly follow the manufacture's 50A guideline?
