What is a double pole 20 amp breaker used for?
Double-pole breakers, on the other hand, are typically rated for 20 to 60 amps and supply 240-volt power to large appliances, like electric dryers and ranges.
How many amps is a 2 pole 20 amp breaker?
This shows that each leg of 30 amp double breaker delivers 30 amps, and not 15 amps. . If a 30 amp double pole breaker was 15 amps on each leg, then a 20 amp double breaker would be 10 amps on each leg.

When should you use a 2 pole breaker?
Double-pole breakers have two hot wires that are connected by a single neutral wire. That means if there’s a short circuit on either of the poles’ hot wires, both trip. These breakers can be used to serve two separate 120-volt circuits or they can serve a single 240-volt circuit, such as your central AC’s circuit.
Does a 2 pole GFCI breaker need a neutral?
It doesn’t make any difference if the load is pure 240-volt (with two hots and no neutral) or 120/240-volt (with two hots and a neutral) — you use the same double-pole GFCI breaker. There will be no connection to the breaker neutral, so just ignore it.
Will a Eaton breaker work in a Siemens panel?
Designed to fit virtually any panel Eaton’s UL classified breakers are designed and tested to be both mechanically and electrically interchangeable with circuit breakers manufactured by General Electric, Thomas & Betts, ITE/Siemens, Murray, Crouse-Hinds, and Square D.
Is a double pole breaker 220?
In a double pole breaker, the electric panel, where the power comes from the transmission line, is wired to each circuit in the house. The line voltage is more or less limited by a transformer mounted on the power pole. This is often reduced to 220 volts from wire resistance and other factors.
How many watts can a double 20 amp breaker handle?
A circuit running on a 20-amp double-pole breaker can have any combination of heaters up to 3,840 watt.
How many outlets should be on a 20 amp breaker?
The question, how many outlets on a 20amp, has no direct answer. This is because the amount of outlets varies according to the number of people living in the home. For instance, a house with four bedrooms will require about 25 outlets and eight ceiling light fixtures connected to one 20 amp AFCI breaker.
What is the maximum load on a 20 amp breaker?
For standard 120-volt service, a 20-amp breaker can support up to 2,400 watts on a single circuit. However, circuits should not be loaded to greater than 80 percent of their maximum capacity for long periods, which makes 1,920 watts the safe maximum for a 20-amp circuit.
What size wire do you need for a 20 amp breaker?
Building codes based on the National Electrical Code prohibit the use of 14-gauge wire anywhere on a 20-amp circuit. All wiring in such circuits must be 12-gauge or larger. The code also prohibits installation of a 20-amp Ground-Fault Interrupter receptacle on a 15-amp circuit.
Can a 15 amp breaker be replaced with a 20 amp breaker?
In most cases a 15 amp circuit breaker is used with 14 gauge wire, and a 20 amp breaker must have at least 12 gauge wiring. Please note that as the wire gauge number goes down, the wire size gets thicker and can handle more power. For this reason, I do not recommend that you simply replace a 15 amp breaker with a 20 amp one.
