240 Volt Circuit Breaker
That s why 240 volt circuits need two hot wires and a neutral to carry the electricity to the appliance plus a ground wire.
240 volt circuit breaker. 120 240 circuit breakers electrical panels protective devices the home depot. The wires usually are black or red but one may be white if it is labeled as hot with a black or red stripe near each end. In the main panel every other breaker is out of phase with the adjoining breakers. While the breaker provides this higher voltage it operates as two linked 120v circuits.
This breaker looks like two standard breakers stacked on top of each other and therefore requires that two breaker positions be open. Get it as soon as fri sep 18.

Siemens q3030 two 30 amp single pole 120 volt circuit breaker. Electricity flowing through your circuit breaker is rated at 120 volts but it is commonly referred to as 110 volts just as electricity at 240 volts is typically called 220 volts. Each 240v circuit has two hot wires as opposed to only one. These breakers can be used to serve two separate 120 volt circuits or they can serve a single 240 volt circuit such as your central ac s circuit.
A 240 volt 3 wire receptacle has three prongs two hot and one ground to accept a 3 prong plug. That means if there s a short circuit on either of the poles hot wires both trip. This is why 240 volt circuits connect to double pole breakers that are essentially two single pole breakers tied together. It takes two 120 volt circuits and a ground wire to form a 240 volt circuit.
The way you get a 240 volt circuit is simple. Siemens q23030ct 30 amp double pole two 30 amp single pole circuit breaker. A double pole circuit breaker is clipped into both 120 buses at the same time so the voltage to the circuit is doubled. A typical 240 volt 30 amp circuit includes a double pole circuit breaker which has two terminals for the two hot wires.
