FAQ:

Q: Can I use a 20 amp breaker on a 30 amp circuit?

A: Back to the original question – per the NEC (210.21 is the section), you can only have 30-amp receptacles on a 30-amp circuit. You can certainly have a 20-amp breaker protecting #10 conductors and use 15 and 20 amp receptacles on the circuit (the 15 amp receptacles are OK providing it’s a multi-outlet circuit). Read, more on it here.

Q: Can I put a 30 amp receptacle on a 30-amp circuit?

A: Back to the original question – per the NEC (210.21 is the section), you can only have 30-amp receptacles on a 30-amp circuit. You can certainly have a 20-amp breaker protecting #10 conductors and use 15 and 20 amp receptacles on the circuit (the 15 amp receptacles are OK providing it’s a multi-outlet circuit).

Q: What size wire do I need for a 30 amp welder?

A: Any circuit fused for 30 amps must use a minimum of 10 ga copper or 8 ga alu. Longer runs may require an upgrade of wire size. In your case, use at least 10 copper for your welder regardless how far it is from the breaker panel. I’m sure one of my buddies here will have a NEC ref for ya.

Q: How many amps does a double-pole breaker use?

A: Double-pole breakers, on the other hand, are seldom rated for less than 30 amps. Electricity comes to the panel through a pair of hot wires with a voltage of 240 volts between them.
