# How many watts is a 20 amp circuit?

20 AMPS x 120 volts = 2400 watts. As you know by now, you can only load up to 80% of the stated rating. What can I plug into a 20 AMP circuit? A 20 amp circuit at 120 volt (80%) will hold 1920 watts.

How many watts can you put on a 30 amp breaker?

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).

## What size wire do I need for a 20 amp breaker?

12-gauge wire is the next size larger and is allowed to carry up to 20 amps. As a result, the amp rating of a circuit breaker has the following relation to the wire size that has been chosen. A 20-amp breaker is never* allowed to run any circuit whose wires (anywhere on the circuit) are 14-gauge.

## What is the maximum wattage for a 20 amp circuit?

For 20 AMP you have 20A*120V or 2400 watts and 15 AMP you have 15A*120V or 1800 watts. Good Electricians will only plan for 80% load so you have 1920 and 1440 watts respectively at your disposal per circuit. Next, find out what’s on the circuit. To do this, leave the lights on that you want to connect to.

## How many watts is in an amp?

Convert watts to amps using the proper equation: Amps equals watts divided by volts. For example, a typical 60-watt light bulb on a standard 110-volt circuit operates at 0.55 amp (60/110). Convert amps to watts by reversing the equation: Amps multiplied by volts equals watts.

## How many outlets can I put on a 20 amp circuit?

One rule of thumb is to assign a maximum draw of 1.5 amps to each receptacle, which allows for 10 receptacles on a 20-amp circuit.

## Can I use a 15 amp plug on a 20 amp circuit?

If there are multiple receptacles on a 20 Amp circuit, the receptacles can be either 15 or 20 Amp (aside from the exceptions). This is to allow You to have multiple devices plugged in drawing less than 15 Amps each, but the total draw on the circuit may be greater than 15 Amps.

## How many watts does a computer use?

A desktop computer uses between 60 and 250 watts, depending on whether it is idle. A laptop consumes 15 to 45 watts. A 22-inch LCD monitor uses an average of 25 watts, while an older 17-inch cathode ray monitor would use about 80 watts.

## How many amps does a 1000 watt light use?

A 1000w HPS or Metal Halide light takes 9 amps at 120 volts so you can only run one on a wall outlet circuit. A standard dryer outlet is 220 volts and 30 amps so you can power up to six 1000 watt lights on that circuit.

## How many amps is a 220 volt outlet?

220 volts 20 amps. This is a 220v 20 amp outlet as shown in the how to 220-volt outlet video likely to be used this for larger power tools in your garage or shop or perhaps a wall air conditioner.

## How many amps does it take to run a refrigerator?

According to the U.S. Department of Energy, the average refrigerator uses approximately 725 watts of electricity and 15 to 20 amps, which can equal 10 percent or more of your home’s total energy usage.

## How many outlets can be on a 15 amp circuit?

I can do the simple math: 180va (or 1.5 amps) per general use receptacle gives a limit of 10 receptacles per 15 amp circuit or 13 receptacles per 20 amp circuit.

## What size circuit breaker should I use for sockets?

Because the breaker rating is much higher than that of any one socket outlet, the system can only be used with fused plugs or fused appliance outlets. They are generally wired with 2.5 mm2 cable and protected by a 30 A fuse, an older 30 A circuit breaker, or a European harmonised 32 A circuit breaker.

## How many amps are in a microwave?

The more watts used the higher the amp draw so keep that in mind. Most microwaves, installed originally in RV’s, are high wattage and can draw 15 amps easily. Further understand that when a microwave, or any other appliance, first comes on it will draw anywhere form 3 – 5 amps more for start-up.

## How many watts is a ceiling fan?

Fans range in size from 36 inches to 56 inches using 55 to 100 watts, a typical 48 inch ceiling fan will use 75 watts. Click calculate to find the energy consumption of a 48 inch ceiling fan using 75 Watts for 3 hours a day @ \$0.10 per kWh.

## How many amps does it take to charge a phone?

An iPhone charger delivers 5 Watts (5 volts at 1000 mA). A Retina iPad mini charger delivers 10 watts (5.1 volts at 2100 mA). While all of these will charge your iPad, using the USB connected to a PC will charge your Retina mini four times slower than if you used the iPad charger it came with.

## How many amps is a 60 watt bulb?

In the United States, most household appliances work at 110 Volts. So the calculation is divide the Wattage by 110. For example: A 40 Watts bulb draws 0.36 Amps to operate. A 60 Watts bulb draws 0.54 Amps to operate.

## How many circuits can you put in a 100 amp panel?

Most breaker boxes are 100, 150, or 200 amps. Add the amperages of all the individual breakers in the box. The total may be more than twice the total amperage of the box. For example a 100-amp service panel may have circuit breakers that add up to more than 200 amps.

## How many outlets do you need in a room?

A. By today’s standards, a bedroom should have one outlet for each 12 feet of wall and at least one outlet on each wall. This may be an older building that predates current electrical standards. However, numerous extension cords create a fire hazard.

## How many amps is a fan?

Low Amps. The majority of modern ceiling fans use less than an amp, averaging between 0.5 and 1 amp, depending on the model and the setting. One amp drawn by a ceiling fan is equivalent to about 120 watts. Low settings use less amperage while higher settings use more.

## How many amps is a recessed light?

The main limitation to the number of recessed fixtures you can run at the same time is the rating of the circuit breaker that controls the circuit. Each fixture with a 60-watt incandescent or halogen bulb draws about 1/2 amp, so a 15-amp breaker for a standard lighting circuit would be able to handle 30 of them.

## How many amps are in a hair dryer?

A 1800 watt hair dryer uses 15 amps (Watts=Volts x Amps) 1800 watts —- divided by 120 volts—- equals 15 amps). Here’s a simple chart. Of course, your appliance may vary. If power goes out and the breaker cannot reset, you have an electrical problem that needs to be found and corrected.
