A single pole breaker is used to supply 120 volts to a 120 volt load circuit and to protect the conductors of that circuit. This is one "hot" wire to the load and then back to the neutral. A two pole or double pole breaker is used to supply 240 volts to a 240 volt load and to protect the conductors of that circuit. This is two "hot" wires to the load without a neutral, eg. baseboard heaters, hot water tanks. The two pole breaker is also used with a neutral when the 240 volt device needs a 120 volt supply for its controls. eg. electric range, dryer.
If you mean a 120 breaker with two switches, those are designed to fit an extra circuit into a full breaker panel by removing the single, installing the double, and you now have two breakers in the space of one, each for the rated amps at 120 volts on the same "leg" of the 240 supply. These are not often recommended and some local codes do not permit them to be used more than temporarily.
What else can I help you with?
Can a 220 VAC breaker be single pole or does it have to always be a double pole breaker?
A 220 VAC breaker can be single pole or double pole depending on the application. For standard 220 VAC circuits like most household appliances, a double pole breaker is typically used. However, in certain situations where only one hot wire is needed, a single pole breaker can be used for 220 VAC circuits.
Should you buy double pole breaker or single pole?
It depends on the specific requirements of your electrical system. Single pole breakers are typically used for 120-volt circuits, while double pole breakers are used for 240-volt circuits. If you are unsure, it is recommended to consult with a qualified electrician to determine the appropriate type of breaker for your needs.
How do you define a pole in circuit breaker?
A pole In a circut breaker refers to the number of circuts it controls, single pole only controls one, double controls 2 at same time
Can a double pole 20 amp breaker be used with 12-2 wire for a single 220 circuit?
The term "double pole" usually means a breaker with 2 handles that attaches in the space as a normal single pole breaker. If this is what you mean, no, you cannot. There is no potential, or voltage, between the wire terminals. If by "double pole" you mean what is usually called a 2-pole breaker, which is a breaker with 2 handles that attaches in the space of 2 single pole breakers, then yes, you can use this breaker and 12/2 wire to produce a 220v circuit.
Can you use two 15 amp single pole breakers in place of a double pole 30 amp breaker?
Yes. An everyday occurrence of this circuitry is in your kitchen counter split receptacles. The top half of the receptacle is a 15 amp circuit and from the same breaker the bottom half of the receptacle is another 15 amp circuit. A two pole single handle breaker is a common trip. If one of the circuits fed from the breaker faults the other connected circuit will shut off also. If you are talking about slot position in a breaker panel, you can remove the two pole breaker and install two single pole breakers.
What is the difference between a single pole and a double pole breaker?
A single pole breaker controls one hot wire and is used for 120-volt circuits, while a double pole breaker controls two hot wires and is used for 240-volt circuits.
What are the differences between a single pole and a double pole breaker?
A single pole breaker controls one wire and is used for 120-volt circuits, while a double pole breaker controls two wires and is used for 240-volt circuits.
What difference between using 4poles circuit breaker and using 3 single pole breakers?
3 pole would be for 3 phase, 4 pole would be 3 phase & neutral
What are the differences between a double pole and a single pole breaker?
A double pole breaker controls two hot wires and provides 240 volts of power, while a single pole breaker controls one hot wire and provides 120 volts of power.
What is the maximum voltage capacity of a 240V single pole breaker?
The maximum voltage capacity of a 240V single pole breaker is 240 volts.
What is the difference between single pole mcb and double pole mcb?
A single pole circuit breaker can protect one hot wire to a given load where as a two pole circuit breaker can protect two hot wires to a given load. In the North American system this would equate to 120 volts on a single pole circuit breaker and 240 volts on a two pole circuit breaker.
Can a 220 VAC breaker be single pole or does it have to always be a double pole breaker?
A 220 VAC breaker can be single pole or double pole depending on the application. For standard 220 VAC circuits like most household appliances, a double pole breaker is typically used. However, in certain situations where only one hot wire is needed, a single pole breaker can be used for 220 VAC circuits.
What is difference between spn and tpn mcb db?
TPN MCB means Triple pole Neutral Miniature Circuit Breaker where as SPN MCB means single phase Neutral MCB.
What is the Largest amperage single phase 120 volt breaker made?
6000amps <<>> The above answer must have big lugs to accommodate 6000 amp capacity wire. In my breaker catalogue the largest 120 volt single pole breaker is 70 amps, 277 volt single pole is 150 amps and 347 volt single pole is 100 amps. The 120 volt single pole breaker occupies two opposed slots because of its length.
What is the difference between a single pole switch and a double pole switch?
A single pole switch controls one circuit, while a double pole switch controls two separate circuits.
Should you buy double pole breaker or single pole?
It depends on the specific requirements of your electrical system. Single pole breakers are typically used for 120-volt circuits, while double pole breakers are used for 240-volt circuits. If you are unsure, it is recommended to consult with a qualified electrician to determine the appropriate type of breaker for your needs.
How do you define a pole in circuit breaker?
A pole In a circut breaker refers to the number of circuts it controls, single pole only controls one, double controls 2 at same time
