your house has 220 you must use a 2 pole breaker. your wiring will change ,not a do it your selfer call someone
can a 20 amp double pole circuit breaker be used for 2 different 120 v circuits using 14 - 2 wire
AWG 12/2 requires the use of a 20 amp single pole breaker.
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.
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.
i think you just have to change the breaker from a 277 to a 120. 277 breakers are usually a 2 pole breaker and 120 is a single pole breaker. NO. 277v is not two poles, it is one pole, one single pole breaker in a 480 volt 3 phase system (typically). If you want 120 volts from a 277 volt source you need a step down transformer 277 volt to 120 volt , or 480/277 to 120/208 .

Two pole what? Switch, breaker? 2 pole does just that. Either switches two separate sources like different legs of a 220 volt circuit or switches both the hot and neutral in a 120 volt circuit or plus and minus in a 12 volt circuit or a two pole breaker takes 2 separate 120v legs in a home breaker panel. Each leg of 120 volt breaker panel is 120 volts to ground and 240 volts between them. The electricity entering your house looks like a sine wave with each leg being 180 degrees out of phase from the other. The double pole breaker takes each separate leg to the device it is powering and provides 240 volts.
Answer for USA, Canada and countries running a 60 Hertz supply service.The 277 volt heater can be wired to a single pole breaker in a 3 phase 4 wire 480 volt distribution panel. The breaker should be sized to the amperage draw of the heater. 277 volts is the star point (wye) voltage of a 480 3 phase system. 480 / 1.73 = 277 volts. The third answer is not correct, two phase legs of a 480 volt system will give you 480 volts. It is the phase leg to ground (neutral) that gives you the 277 volts.A 277 Volt heater or device may not be wired to a 480 Volt circuit or box. A 277 Volt device may only be wired to a circuit rated for 277V/480V equipment.2 legs of 480 volts will give you 277. But since you don't know the answer you probably shouldn't be doing it! Please don't kill yourself, hire a licensed electrician.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energizedIF YOU ARE NOT REALLY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
A single phase circuit uses a 2 pole breaker if the circuit is 120/240 split phase and the load is connected 240. Both legs are hot, so both need to be protected. This is the normal US/Canada configuration.
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.
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.
Answer for USA, Canada and countries running a 60 Hz supply service.Before an explanation of how to do this you should keep in mind that this is for a single receptacle only. If any other receptacles are on the same circuit they will also be changed to 120 volts.The existing two pole breaker in the distribution panel that is to be replaced should not have a larger rating than a 15 or 20 amps. The wire size from that breaker will be #14 or #12 respectively. The final results of this project will leave you with a 15 amp 120 volt receptacle and one spare 15 amp breaker in the distribution panel.That said, OK, any 240 volt outlet can be changed to 120 volt by removing the white wire from the 2 pole breaker and inserting it into the neutral bus bar. Remove the other wire (probably black) from the breaker. Remove the 2 pole breaker from the breaker panel. Install two single pole 15 amp breakers into the hole left by the 2 pole breaker. Leave both of these breakers turned off.Connect the black wire that came off of the 2 pole breaker on to one of the new single pole 15 amp breakers. Re install the cover to the electrical panel, this end is finished. At the old 240 volt receptacle, remove the existing device and install a new 120 volt receptacle.Materials can be purchased at local building supply store. Remember to take the electrical panel data with you so you have the information for the 2 new breakers. Once you have the new 120 volt receptacle installed, identify on the electrical panel door what the breaker is used for. Leave the unused breaker in the off position. Turn the new 15 amp breaker on. Turn the main breaker back on. Test the new receptacle with a lamp to make sure every thing is OK.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliancesalways use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
That unit requires 2 40 amp breakers (2 pole). each wire will go one side of a two pole (220V) breaker.
No. If your AC is currently running on a 30 amp 2 pole breaker, then it is a 220 volt unit. You cannot substitute one 60 amp single pole breaker as you'll only be supplying 110 volts and the AC unit won't work. In fact you could damage it.
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
