How do you connect wire to a breaker?
There is 220 volts between the two poles. If you are running 2 wires (black and white) + ground then you hook black to one pole and white to the other. Put red or black electric tape on each end of the white wire and wrap around wire for 3 inches or so next to the connection so the next person will be able to see that the wire is hot and not a neutral.
How do you hook up a water heater with red black and white wires?
Sounds like it is a 220-240 Volt hot water heater. The black and red are connected to the 220 volts supply and the white is connected to Neutral. At the breaker panel red and black connect to the 2-pole 220 volt breaker and white goes to the neutral bus bar.
Can you only use white and black wires on a 2 pole breaker?
Typically the black wire is "hot", and the white wire is neutral. A 2 pole breaker is most commonly used for 240 V, and as such, you would typically use a 3 conductor wire, with black, red and white (+ ground). In a typical application, the black and red are used in the 2 pole breaker, and neutral is connected to the neutral bar in the breaker panel.
Can a double pole circuit breaker be used for 2 different circuits I have a 20 amp double pole breaker want 2 circuits running 14 gauge wire?
can a 20 amp double pole circuit breaker be used for 2 different 120 v circuits using 14 - 2 wire
Is a double throw 15amp breaker the same as a 30 amp breaker amp?
You have a double pole breaker for 240Volt supply. The maximum current is 15 amp.
How many wires are used for a 460 volt circuit breaker?
If the load is single phase and the load requires 460 volts to operate, then two conductors will be needed and they will connect to a two pole breaker. If the load is three phase and the load requires 460 volts to operate, then three conductors will be needed and they will connected to a three pole breaker. The sizing of the wires will depend upon the current that is drawn by the loads.
Rating of a 3 pole circuit breaker is the same for each conductor?
Yes, the rating of a 3 pole circuit breaker is the same for each conductor that is connected to it. A three pole breaker rated at 30 amps will have 3 #10 wires from it that connect to the load.
Found 2 wires on a single circuit breaker why?
If it was two wires under one screw on a single-pole breaker, that would not be proper, and most probably against electrical code.If it was two wires, each under their own screw on a double-pole breaker, then that would be a 220 volt circuit; each wire going to its own "leg" of the breaker panel.
How many wires can be connected on to a 20 amp breaker in NH?
Code only allows one wire to be connected to a single pole breaker. Any additional circuitry has to be done in a junction box downstream from the breaker.
How can I connect a single-phase - 2 hot wires plus ground- 220V load to a 3-pole 220V breaker?
Common usage of a three pole breaker is for use on a three phase distribution panel. Single phase distribution panels only use two pole breakers for a 240 volt load.Remember that the breaker must protect the conductors that connect to the load. If you want to try and use a three pole breaker in a single phase panel just because you have the breaker, this is not a good idea even if it will fit.Purchase the proper single phase two pole breaker to match the wire size and the amperage of the connected 240 volt load. Keep in mind that connected 240 volt motor loads have to be sized to 250% of the motor's full load amperage.By doing what you want to do and a fault occurs from this type of installation your insurance company might not cover the damage that it would cause.If the distribution panel is three phase then just connect the two load wires to any two of the three poles on the breaker.
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.
How do you wire a 220v connection into the main panel?
I assume you mean you are wiring a 220 volt circuit. You will install a 220 volt double pole breaker of the correct size for the circuit. An example would be for an electric dryer that requires a 30 amp double pole breaker wired with 10/3 wire. You connect the Red & Black wires to the breaker. One on each screw. You now connect the White wire to the neutral bus bar in the service panel. Then connect the bare copper ground wire to the ground bus bar in the service panel. At the dryer outlet connect the black & red to the hot screws, white to the neutral, and ground to ground. They will be labeled on the back of the outlet.
How many pole breaker for air condition?
If the power requirement is 120 volts it will be connected to a single pole breaker rated at the amperage requirement of the air conditioner. If the voltage of the air conditioner is 240 volts, then a two pole breaker will be required.
Should you buy double pole breaker or single pole?
Use of a double pole breaker or a single pole breaker depends entirely on the application. If you don't know about the application, contact a qualified electrician in your area.

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.
