## What is power rating of an appliances?

Every electrical appliance has a power rating which tells you how much electricity it needs to work. This is usually given in watts (W) or kilowatts (kW) (1000W = 1kW). Of course, the amount of electricity it uses depends on how long it’s on for, and this is measured in kilowatt-hours (kWh).

### How do you find the power rating of an appliance?

Power ratings of most appliances are usually listed on the appliance itself or the manual. For a final calculation of your watt-hour usage, we recommend that you look at each appliance to be powered to find its rated power.

Which appliance has the highest power rating?

The fridge Your fridge will, in most cases, be the appliance that uses the most power and can consume up to a third of all the power in your house.

What is the power rating of refrigerator?

The average home refrigerator uses 350-780 watts. Refrigerator power usage depends on different factors, such as what kind of fridge you own, its size and age, the kitchen’s ambient temperature, the type of refrigerator, and where you place it.

## What is the power rating of washing machine?

How much electricity does a washing machine use? On average, a washing machine uses 400 to 1,400 watts (W) of electricity, depending on the model. Most washing machines use between 5 and 15 amps, and connect to a 120 volt outlet.

### How do you calculate kW rating?

Multiply the motor voltage by the full-load current. The result is in watts. Divide watts by 1,000 to give kilowatts. For example, 230 volts x 20 amps = 4,600 watts; 4,600 watts divided by 1000 = 4.6 kilowatts.

What is the power rating of a refrigerator?
