The type and size of a wire for a 240 volt air conditioner will depend on the amperage the unit draws.
A single pole switch interrupts only one wire, which must be the live wire. A double pole switch interrupts both the live and the neutral, so it contains two separate switches operated by the same lever. Current practice is to use single-pole switches, to avoid a fault condition which could leave equipment live while switched off.
there is no answer a single pole socket is a 120v and a double pole is 240v if you are talking about contactors it is completely up to the appliance but a double pole double throw is just as safe as a single pole single throw contactor, Example a single pole single throw will only disconnect the "hot" wire, not the neutral or ground wire and thus no voltage will pass however with a 240 v circuit a double pole single throw only disconnects one "hot" wire and will still have voltage through the circuit (120 volts not 240 though)and is not as safe as a double pole double throw that will disconnect both "hot" lines so no voltage is in circuit If you need electrical work done and do not completely know how to wire it up to code and be safe in the process hire a professional! >>>ITS WORTH YOUR LIFE<<<
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.
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.
you can use two hot wire different phases with a double pole braker .
A single pole switch interrupts only one wire, which must be the live wire. A double pole switch interrupts both the live and the neutral, so it contains two separate switches operated by the same lever. Current practice is to use single-pole switches, to avoid a fault condition which could leave equipment live while switched off.
To wire a double pole breaker correctly, connect the hot wires to the breaker terminals and the neutral wire to the neutral bus bar. Make sure to follow the manufacturer's instructions and turn off the power before starting.
can a 20 amp double pole circuit breaker be used for 2 different 120 v circuits using 14 - 2 wire
To wire a double pole switch, connect the two hot wires to the two brass terminals and the ground wire to the green terminal. Make sure to turn off the power before starting and follow the manufacturer's instructions for your specific switch.
A switch is inserted in series with a single wire. When the switch is on, it is as if the wire had not been opened to insert the switch. When the switch is off the wire is open and no current can flow. All a double pole switch does is allows you to switch two separate wires at the same time with the same switch action. A single pole switch just switches one wire.
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.
ICDP Stands For Iron Clad Double Pole. It is also known as Main Switch. It contain two fuse. One is for phase wire and another is for neutral wire.
A 2-pole wire will not work on a 3-pole plug. You will need to use a 3-pole wire on a 3-pole plug.
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.
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.
To properly wire a double pole breaker for 240V, connect the two hot wires to the breaker terminals, the neutral wire to the neutral bus bar, and the ground wire to the ground bus bar in the electrical panel. Make sure to follow the manufacturer's instructions and local electrical codes for safety.
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.
