What are the advantages and disadvantages of a double pole circuit?

A double pole switch can be used in either a 240V application where you'll need to disconnect 2 "hot" lines, or it is useful when switching a light from 3 different switches.
Disadvantage?
I suppose it could be a little confusing to face all those contacts on a double pole switch.

∙ 8y agoAll circuits have to be two pole in order to work. I presume you mean the switch, or circuit breaker.
A circuit will stop working if only one pole is disconnected. It will however, leave the remaining pole connected. For safety, and when someone needs to work on a circuit and touch the wires, it is better to break both poles and make the circuit totally disconnected.
Two pole switches are of course more expensive and usually harder to switch.
So, for domestic circuits, where it is only required to stop something working, without exposing wires, single pole switches are cheaper and quite sufficient.
In domestic power circuits, two pole breakers are used at the distribution box, to make the system safe for maintenance.

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.
On which line is the switch of electrical appliance connected?
A Switch on a domestic supply has always got to be on the LIVE part of that circuit. A double pole switch switches both the LIVE and NEUTRAL off together.
How do you select an MCB?
While selecting an MCB you have to check: 1) Current Rating; 2) Response Time; 3) Manufacturer; 4) Type of MCB (means single pole, double pole, three pole, four pole - it depends on the application); 5) Cost; 6) short circuit breaking capacity.

Can a 220 VAC breaker be single pole or does it have to always be a double pole breaker?
U.S. 240 VAC breakers are always double pole since they are protecting two legs of the circuit.

Can double pole circuit breakers be changed into single to create more room in the pannel box?
Yes. The double pole breaker can be removed and replaced with two single pole breakers. The double pole breakers are only used for 240 volt supply loads.

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<<<
What are the advantages and disadvantages of the Gnomonic Projection map?
