Does a double breaker mean 240 volts?

The breakers themselves are relatively narrow and occupy a single slot in the home’s breaker box. 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.

What does 3 pole breaker mean?

Three pole circuit breakers deliver 480VAC through three hot wires. Consequently, the breaker needs three separate switches that will work together when needed. It’s effectively three single pole breakers bound together. With connections for five wires, it’s three times the width of the single pole breaker.

Can a 20-amp breaker handle 240 volts?

20-amp 120-volt circuit: 20 amps x 120-volts = 2,400 watts. 25-amp 120-volt circuit: 25 amps x 120 volts = 3,000 watts. 20-amp 240-volt circuit: 20 amps x 240 volts = 4,800 watts. 25-amp 240-volt circuit: 25 amps x 240 volts = 6,000 watts.
