I am replacing a 10 year old electric oven. There are actually two ovens I am replacing. There are four wires times two coming out of each conduit for each of the ovens. They lead to the circuit panel where there are 2 (two) 30 amp breakers connected to one another for each oven circuit. So 2 sets of 2x30 breakers. My oven model is rated at 3.6kw so the install instructions say it should have a separate 20amp breaker. Can I just connect it to the 2x30amp breakers or do I need to install lower, 20 amp breaker?
