*Appliance wattages vary. These figures represent averages only.
**Allow up to three times the normal running watts for starting these appliances or cycling their compressors.
How to Calculate Wattage
If you are unable to easily locate the appliance wattage, you can calculate it yourself. Look for labels inside or on the back of the appliance, check operating manuals or contact the manufacturer. Find the AMP and VOLT listings for the appliance.
AMPS X VOLTS = the constant wattage of your appliance
Remember, motor-driven appliances like refrigerators, freezers, air conditioners and furnace blowers, require up to three times their normal wattage to start or periodically cycle a compressor.
