      What is the difference between a 1 pole and 2 pole 20 amp breaker?

      Administrator

      Single-pole breakers: Provide 120 volts, 15-20 amps and have one hot wire and one neutral wire. Double-pole breakers: Provide 240 volts, 20-60 amps and have two hot wires that share one neutral wire.
