## Do I need 15a or 20a outlets?

You can use a device that has a 15-amp plug with either a 15- or 20-amp receptacle. Standard 15-amp receptacles are suitable for typical household appliances, lamps and other accessories. A 20-amp receptacle is for heavy-duty appliances and power tools, such as air compressors.

## What is a 20a plug?

The 20 amp outlets are designated for big consumption appliances and power tools, like air compressors, so it is not unusual to find them in almost every kitchen and sometimes even in garages.

**Can I plug 30 amp into 20amp?**

Yes, you can connect your 30 AMP RV to a 20 AMP outlet. You’ll be restricted in what you can run connected to a 15/20 Amp electrical outlet because your RV will require at least a 30/50 Amp hookup to power the rig.

**Can you plug a 20 amp appliance into a 30 amp outlet?**

If you plug an appliance with a 25-amp power draw to the outlet, the outlet will begin to fail. However, since 25-amp is still below the circuit breaker’s capacity, it will not trip. That’s why you can’t use a 20 amp or 15 amp outlet on 30 amp circuit.

### What’s the difference between a 15 amp and a 20 amp outlet?

15 Amp vs 20 Amp Outlet: How To Tell Them Apart Receptacles with a 20 amp current have a similar design to the 15 amp ones, with a single exception: an additional horizontal slot, which forks from one of the vertical slots (picture on the right). This enables 20 amp plugs to be inserted directly into the outlet.

### What is the difference between a 20a and a 15a?

A 20a receptacle has one slot that is turned sideways or T shaped to allow a 20amp plug to be used. A 15amp receptacle won’t overload the circuit. Only 15a devices will be allowed to be plugged in.

**Can a 20 amp generator run a 30 amp RV?**

Since your RV will need at least a 30/50 Amp hookup to power the rig, you’ll be limited in what you can run connected to a home’s 15/20 Amp electrical outlet. Plug the extension cord into your RV’s electrical hookups via an adapter, if necessary.

**Can I use a 20 amp generator for a 30 amp RV?**

A generator that provides at least 4000 watts of continuous output should be more than enough to handle what most people would need in an RV. In order for your generator to be compatible with a 30 amp outlet, it will need at least 4000 watts of continuous output (120 volts x 20 amps).

## What is better 15 amp or 20 amp?

20-amp circuits are designed for a heavier load of electrical current than 15-amp circuit breakers. For commercial and industrial power distribution, the circuit breakers will have a higher amperage.

## How many watts can I run on a 20 amp circuit?

2,400 watts

20-amp 120-volt circuit: 20 amps x 120-volts = 2,400 watts.
