What is a double pole 40 amp breaker used for?
Double-pole breaker The 15-amp and 20-amp breakers often handle baseboard heaters, 30-amp serve water heaters and electric dryers, 40- and 50-amp are for electric ranges, and the 70-amp could serve a large air conditioner or a subpanel.
What is the purpose of a double 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.
How many watts is a double pole 40 amp breaker?
9,600 watt
A 40-amp circuit is equivalent to 9,600 watt.
Is a double pole breaker twice the amps?
Since each leg of 240 volt circuit offers 120 volt potential to ground, then you’re getting two legs of out-of-phase 120 volt when you use double breaker, and doing so doubles the voltage and doubles the watts (power), it does not halve the amps.

How much load can you put on a 40 amp breaker?
40-amp 240-volt circuit: 40 amps x 240 volts = 9,600 watts. 50-amp 240-volt circuit: 50 amps x 240 volts = 12,000 watts.
How many amps can a 40 amp breaker handle?
There is a 40-amp circuit with a maximum output of 9,600 watt. 12,000 watt is equal to 50 Amps x 480 Amps.
How many amps is a double breaker?

What is a 40 amp breaker?
a 40 amp breaker would be marked “40”. If your oven is connected to a double pole 20 amp breaker, and it’s an oven ONLY, with no cooktop on the same circuit, it’s possible that it draws less than 20 amps.
What is a double pole breaker?
“Double pole” circuit breakers are used in this case, which consist of two single circuit breakers whose trip handles are physically tied together. That way, if either “hot” leg draws too much current, both breakers will trip simultaneously, effectively stopping all voltage to the appliance.
