This type of question usually means you aren't ready to do this yourself. Study some electrical material and the National Electrical Code and work this answer out for yourself. If I were to give you an answer, you might attempt to do something you shouldn't be doing, and that may cost someone a shock, a home fire, or their life. The NEC covers branch circuits in Article 310. Your answer is in there.

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 switch from 15amp to 20amp on a double pole breaker?

The minimum size wire a 20 amp breaker needs to be connected to is a #12 wire. The 15 is probably connected to a #14 right now which is only rated for 15 amps. Remember the breaker is sized to the wires ampacity not the load .


How can you wire a normal 120V outlet out of a double pole circuit breaker?

well, the easy answer is, black wire to one pole of the breaker, white wire to the neutral bus with all the other white wires, bare wire to the ground bus with all the other bare (or green) wires. BUT the breaker must be 20 amps or less for residential outlets and you much match the wire size to the breaker, #14 for 15 amp breaker, #12 for a 20 amp breaker AND if there is only going to be one outlet, if it is a 20 amp circuit, the outlet has to be rated for 20 amps. Yes, but why would you want to? It is unclear to anybody else what you are doing and therefore a hazard. Do it right. Use a single pole breaker designed for 110V.


When installing a circuit breaker do you size the breaker to correct wire size or the device its controlling?

When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.


Can you use a double pole 15 amp breaker in place of a 20 amp single pole breaker for a 12000 BTU air conditioner?

If the 12,000 BTU A/C only requires 20 amps to run then yes you can use the same 12 gauge wire but you cannot change it to a 15 amp breaker. You will need to install a 20 amp double pole breaker. If it requires more than 20 amps you will have to replace the wiring and breaker.

How do you tap off existing unused 220 wire and convert it to 110 for a plug in?

Take out the double pole breaker, place the white wire on the grounding bar along with the ground wire, install singe pole breaker(size needed) attach black wire onto new breaker and you now have 110 line.

Does a double-pole 30A breaker pull 15A per leg and if so why can't 14 gauge be used since 14 is rated for 15A?

A double pole 30 amp breaker can pass 30 amps per pole, therefore #10 wire should be used.

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.
