A two pole breaker clips to adjacent buss in the breaker panel, supplies 240 volt power to equipnent like clothes dryers and air conditoning.The breakers have a mechanical common trip so if either pole exceeds its current rating both lines are opened shutting down the equipment.Each pole can carry up to its rated current of 30 amps.Hope this helps.

What pole on a square d circuit breaker gets the black wire?

In a Square D breaker panel, the two hot legs are fed through the center buss bar and breakers snap to the panel getting their power from the bars that run through the center, and the WHITE wire is connected to a neutral strap that has multiple connections for the neutral wires of each circuit. When connecting a circuit to the breakers, the BLACK or RED wires are connected to the breakers and the WHITE wires are connected to the neutral strap. I seriously recommend that you work with a qualified electrician to help with any new electrical work or electrical modifications. There are far too many ways that you can introduce serious hazards to your home if you make a mistake in the wiring. Even if you hire a retired electrician to help you, he could give you the pointers that will make your wiring project more safe for you, your family and your property. Do NOT attempt any wiring project if you do not have a good understanding of this and other, similar issues.

How does a telescoping pole work?

A telescoping pole works by offering a hollow pole that is designed with segments that slide into each other. Each segment is slightly smaller than the next as you move toward the top of the pole.

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

All 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.

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.


How do you work air circuit breaker with air?

circuit breakers are switches that open quickly usually opening with a fault condition air circuit breakers need a long path to quench the arc oil filled circuit breakers quench arcs much more effectively and in a smaller space vacuum breakers have no media for an arc to propagate and are far smaller fuses generally are filled with silica sand to quench the arc and higher currents make the arc path much longer typical AIC fuses 200,000A air breakers 15,000A oil breakers 50,000A vacuum breakers 100,000A fuses work once and work correctly and dont fail or weld closed they are inexpensive and safe breakers can work tens of times breakers need rework and recalibration whenever they are reset breakers have mechanical moving parts tempered springs and require periodic maintenance and testing Breakers can weld shut with a short

How do you know what the voltage of your electric baseboard heater is if there is no label on the heater?

Go to your power panel and look for two pole breakers. If there are any 20 amp two pole breakers there is a good chance that they are for the baseboard heaters. Switch this breaker off and turn your thermostat up. If the baseboard heaters do not come on and get hot then this is the supply for them. A two pole breaker is supplying 240 volts to the heaters. Most likely there will be more that one heater on the circuit. 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 appliances,always 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.
