a double pole breaker is designed to protect 220 volt circuits (hot water heater or stove). A 220 volt circuit has two hot lines and the double pole breaker will trip if either line exceeds the breakers current limit. By operating in this way, the breaker opens both sides of the circuit and completely isolates the appliance.

Double pole circuit breakers protect the wires from over current on 240 volt circuits and on multi wire 120 volt circuits.

Double pole breakers are used for 220 volt circuits, such as larger window or central air conditioners, electric dryers and electric ranges. These are multiple element or motor appliances that draw significant power upon start-up. The best way to make the appliance efficient is to divide the circuits it. Hope this answers your question.

double pole breakers, with both of the handles tied together are used on 240V circuits such as dryers, ranges, etc. they are made to trip both hot wires off at the same time if amperage is exceeded. there is not one wire carrying 240 volts, there are two wires carrying 120 volts each, one is black and one is red.

The neon light does NOT indicate a fault that is not its function - it merely shows that power in on. The fact that it is on all the time just indicates that the load and feed cables are in the wrong positions and just need changing over. I appreciate that you may have carefully copied wire for wire when you changed the switch but all makes of switch are not the same and some put load and feed in different locations, just change the cables over and all will be well. There is nothing dangerous in what you have done - your just not getting the full benefit of having a neon light. ..

Usually for a 240 volt circuit.

So that each wire is protected independent of the other.Otherwise, it would be the collective current that would cause it to trip the breaker, which is the same if one wire carried it all and started a fire while the wire carried none.however, if either wire causes the breaker to trip then both are disconnected from the power source.

It completely isolates both legs of the circuit. It is a safer breaker because the circuit is completely dissconnected on both sides, not just the hot side.

It disconnects both live wires if either wire is carrying too much current. If there were two separate ones one could disconnect but there could still be voltage going through the other one that could kill someone trying to troubleshoot the problem.

to provide 230V single phase power for ranges, water heaters, dryers, and HVAC units
