Aluminum wiring and induction cooktop
I'm planning to replace a electric radiant heat cooktop with an induction unit. Existing wiring is aluminum romex with a 40A breaker. I measured the thickness of wire using a wire gauge and it's 3/16". So it's either a #4 or #6 cable. The new unit is rated at 10.8 KW and requires a 50A circuit.
I read somewhere that a household cooking appliance of up to 12KW can work with a 40A circuit. Can I just connect the cooktop to existing circuit?
