When can I use a 30 amp breaker?

A 30 amp breaker is usually used with one dedicated outlet, as for an electric range or clothes dryer, and usually with 240V (in the U.S.) Normal duplex convenience outlets are usually used with a 15 amp or 20 amp circuit.

Can 14 gauge handle 30 amps?

How is it safe? A dead short in the #14 branch will draw up to 30 amps of current through the #14 wire. @Bryce: A dead short on the #14 branch would pass a lot more than 30 amps, but would only have to do so long enough to trip the breaker.

What does it mean when two 30 amp breakers tied together?

Meaning, if you have a two pole 30 amp breaker (such as for your pool) this means that you have a total of 30 amps. You do not multiply the marked amps on the breaker by 2 to get 60. Same thing goes for the 40amp 2 pole breaker. It is still a total of only 40 amps not 2 times 40 equals 80 amps.

How many watts can a 30 amp breaker handle?

3,600 watts A 30-amp outlet supplies 3,600 watts (30 amps multiplied by 120 volts). Therefore, the breaker on that outlet could meet code and still trip anywhere between a total load of 2,880 watts (80 percent of 3,600 watts) and 4,320 watts (120 percent of 3,600 watts).

When should you use a 20 amp receptacle?
