A 30 amp plug has three prongs – a 120 volt hot wire, a neutral wire and a ground wire – and is generally used on RVs with lower load requirements.

What can you run off of a 30 amp breaker?

In a typical RV with a 30 amp electrical service some of the power hungry appliances and portable devices are the air conditioner, electric water heater, microwave, coffee maker, electric skillet, hair dryer, space heaters and a toaster.

How many outlets can I run on a 30 amp breaker?

The NEC states that you can only have 30-amp receptacles on a 30-amp circuit. If its a multi-outlet circuit, you can have a 20-amp breaker protecting the #10 conductors and use 15amp and 20amp receptacles on the circuit.

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. A 30 amp breaker requires #10 wire, which does not work with duplex outlets.

Whats the difference between 20 amp and 30 amp?

The difference between the 20a and 30a is the plug. If you have a standard polarized plug with two vertical prongs and one ground prong get the 20a. If your outlet has one vertical and one horizontal prong with the grounding prong get the 30a.

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?

A 20-amp receptacle is for heavy-duty appliances and power tools, such as air compressors. Residential garages occasionally have 20-amp receptacles to accommodate larger power tools.
