What is difference between single pole and double pole switch?
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.
Which is best double pole or single pole power socket?
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<<<
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.
How do you tell a single pole breaker from a double pole breaker?
AnswerAccording to my husband, all sockets are double pole, single and double pole refer to switches. Hope that helps. Double pole isolates both neutral and live, single pole only isolates live, double is better, but single is cheaper. DP-switched sockets have only become commonplace in relatively recent times anyway, marketed on yet another "increased safety" angle when there was never any safety problem with SP to begin with.
How you can produce 240 volts from a single phase 3 wire system with a nominal voltage of 120 volts?
you can use two hot wire different phases with a double pole braker .

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
How does a double pole switch work?
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.
Can a double pole 20 amp breaker be used with 12-2 wire for a single 220 circuit?

What is ICDP switch?
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.
Will a 2 pole wire work with a 3 pole plug?
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.
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 you use a 12-3 romax for a double pole 40 amp breaker It is for a mig welder?
No, the wire will overheat.
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.
How do you wire a DPST switch?
A double pole single throw switch. used to switch two lines at the same time.
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.
