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?
The average home refrigerator uses 350-780 watts.

What is kW rating?
To expand on it a bit more, the kW rating is essentially the resulting power output a generator can supply based on the horsepower of an engine. kW is figured by the horsepower rating of the engine times . 746. For example if you have a 500 horsepower engine it has a kW rating of 373.

What do energy rating labels on appliances mean?
Appliances—such as entertainment devices, white goods and cooking equipment—can together account for 30% of home energy use. Energy rating labels provide consumers with information on the energy efficiency of a range of appliances. The more stars, the more energy efficient the product is compared to other models in its category.
What do the energy ratings on natural gas appliances mean?
The gas appliance energy rating label covers these natural gas appliances: For products without energy ratings, find out their energy usage and compare with similar products. Some imported products have the American ENERGY STAR label. This scheme is supported by the US Government.
How do I know how much power my appliances use?
You can also buy a power meter specifically designed to measure how much power an appliance consumes. When determining how many Watt-hours your appliances will use, keep in mind that many of the appliances you use will only be run for an average of a few minutes per day.
