Doing another rehab and noticed the electric wall oven may have a problem. According to the specs it requires at max 27amps so I assume a 30 amp circuit would be OK. I found it is fed with a 40amp circuit on #8 wire. Is it OK to have a circuit that is at least 10 amps larger feed this oven? My concern is if for some reason something went wrong in the oven would the breaker trip before the oven is damaged or something in the oven starts smoking, other than my cooking?
The installation instructions for ranges will specify the circuit/breaker recommended depending on the model. You may be able to find that document on the manufacturer's web site. Or call and ask the manufacturer what is recommended for that specific model.
