If you are talking about splicing a 40 amp cook top into an existing 3C #10 30 amp circuit then the answer is no. An appliance with that load ampacity needs to have its own dedicated circuit. This would consist of 3C #8 wire cable fed from a two pole 40 amp breaker located in the distribution panel.
A circuit breaker protects the wires that the devices are connected to. If the devices that are connected to the circuit are 20 amps the wire size should be #12 wire fed from a 20 amp breaker. This breaker should not trip unless the circuit is overloaded or a fault occurs on the circuit. If the devices that are connected to the circuit are15 amps the wire size should be #14 wire fed from a15 amp breaker. This breaker should not trip unless the circuit is overloaded or a fault occurs on the circuit. Putting 20 amp sockets on this 15 amp circuit will work but the circuit is limited to the amount of load that can be plugged in. You will not get the full capacity of the 20 socket because the breaker will trip at 15 amps.
Using a wire rated for 100 amps for a 60-amp circuit is generally fine. It's important to ensure that the wire gauge matches the amperage requirements to prevent overheating and potential fire hazards. Check local electrical codes to confirm that it is within regulations.
For a 20 amp circuit, a 12-gauge copper ground wire is typically recommended. This wire size can safely handle the current and provide proper grounding for the circuit.
Using larger wire sizes will not reduce amp draw. The amp draw is determined by the electrical device or load connected to the circuit, not the wire size. Larger wire sizes are used to reduce voltage drop and heat generation in the wiring, but they do not directly affect the amp draw of the circuit.
Using 14-2 wire on outlets is not recommended because it is typically rated for 15 amps, while outlets are often connected to a 20 amp circuit. This could potentially overload the wire, leading to overheating and posing a fire hazard. It is safer to use 12-2 wire for outlets connected to a 20 amp circuit.
Since the resulting short circuit would be outside the amp, it WOULD NOT blow the amp.
