No. In North America a double pole breaker is used to obtain a voltage of 240 volts from the distribution panel. What ever the amperage rating stamped on the handle of the breaker is, that is the amperage that the breaker will trip at.

Does a double 50 amp breaker make a 100 amp?

No, a double pole 50 amp breaker protects a 240 volt supply at 50 amps. The number that is on the handle of the breaker is the amperage that the breaker will trip at if an overload occurs on the circuit.


What amperage is a dual 60 amp breaker?

120 amps The above answer is wrong. A 60 amp breaker is designed to trip at 60 amps be it a single pole, double pole or a triple pole that is used on three phase equipment. The number on the handle of a breaker is the trip capacity.


What is the difference between a single pole breaker and a double pole breaker?

A single pole breaker is made or used to protect the panel buss for 110 volt devices, A double pole breaker protects the buss for 220 volt devices.


Should you buy double pole breaker or single pole?

Use of a double pole breaker or a single pole breaker depends entirely on the application. If you don't know about the application, contact a qualified electrician in your area.


How many pole breaker for air condition?

If the power requirement is 120 volts it will be connected to a single pole breaker rated at the amperage requirement of the air conditioner. If the voltage of the air conditioner is 240 volts, then a two pole breaker will be required.


Can you use a 25 amp double pole breaker for a 240 heavy duty whirlpool dryer.?

The recommended breaker for dryers is 30 amps. If you want to do the calculation to see if a 25 amp breaker will work use the following formula. W = A x V, A = W/V. Find the wattage of the unit and divide it by 240 volts to get the amperage. If the amperage is under 25 amps then the breaker will work. If the amperage is over 25 amps then a 30 amp breaker on #10 wire will be needed.


Can a double pole 30 amp breaker be used as a 15 amp single pole breaker?

No, it is a 30 amp breaker on each side. Remove it and install a 15 amp single pole breaker.


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 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.


Is a double throw 15amp breaker the same as a 30 amp breaker amp?

You have a double pole breaker for 240Volt supply. The maximum current is 15 amp.


Is a 2 pole 30 amp circuit breaker equivalent to two single pole 15 amp circuit breakers?

No, the number on the handle of the breaker is the maximum amount of amperage the breaker will handle before it trips. A two pole breaker is handling 240 volts. A single pole breaker handles 120 volts. Each of the "hot" wires from the two pole breaker has a potential of 120 volts to the neutral wire, but 240 volts from one "hot" wire to the other "hot" wire.

Is the amperage of a breaker for total amps combined or on each leg?

Answer for USA, Canada and countries running a 60 Hertz supply service.Combined. A two-pole 100A breaker will draw 50A on each leg. A three-pole 100A breaker will draw 33A on each leg.>People have funny concepts about electricity , the above is totally false. A two pole 100A breaker will draw 100A on each leg. A three pole 100A breaker will draw 100A on each leg. The number that is marked on every breaker is the amperage that the breaker is designed to trip at. Sheer reason should tell you that if you wanted to protect a 240 volt load at 50 amps you would not install a breaker that has 100 amps marked on it.


What is the size breaker per phase 200kva generator?

A breaker is not sized by individual phase amperage. It will be a three phase or three pole breaker rated at the output of the generator. Use the following formula to find the output amperage of the three phase generator. Amps = kva x 1000/1.73 x voltage.


What is a 15 amp double pole breaker?

A double pole breaker has one pole attached to one side of your breaker panel's bus or hot leg, and another pole attached to another hot leg or bus, if it is in a residential panel (in the US) each leg of the breaker is 120 volts to ground or neutral and 240 hot leg to hot leg. The 15 amp indicates that the breaker will trip if the circuit exceeds 15 amps across the two outputs of the breaker.


Can a double pole 15 amp breaker help?

Help what? A double pole breaker is usually for 220/240 volt applications, but can be used for two 110/120 volt circuits. Also would depend if it is single or double throw.


Will cobwebs trip a breaker?

No, a breaker is an amperage activated device.


How do you tell a single pole breaker from a double pole breaker?

A single pole breaker will take up one single slot in a household distribution panel. A two pole breaker will take up two slots in the distribution panel. Older double pole breaker installations had two breakers side by side with the two switch handles physically tied together. Today two pole breakers are one unit containing two output terminals for the output circuit. This new configuration has only one handle to operate both sides of the breaker for shutting the circuit off and resetting a tripped breaker.


When going from 1-240v to 2-120v circuits do you need to replace the double pole breaker?

Yes, otherwise your double pole breaker will shut the other circuit off when one of them trips.


What is the amperage for a clothes dryer?

Can you use a 220 breaker in place of 110 breaker on 110 service?

Answer for USA, Canada and countries running a 60 Hz supply service.Breakers are rated in amperage and by the amount of poles that they have. Your classification of a 220 breaker is described in electrical terminology as a two pole breaker.Choosing the amperage of the two pole breaker depends upon the 220 volt load that it feeds.Two pole breakers for 220 volt loads.Single pole breakers for 120 volt loads.If the service is only 120 volt then every other bus bar in the panel will be energized. If the panel is a 120/240, then every bus bar in the panel will be energized.This is how and why a 240 volt load requires a two pole breaker.To the answer, yes you an use a two pole breaker in a 120 volt service but only one side of the breaker will have voltage on it depending on where it is situated in the panel board.



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.
