(a) Hard-starting motors require 3-5 times the rated running watts
(b) For extremely hard to start loads, such as air conditioners and air compressors, consult the equipment dealer to
determine maximum wattage.
To calculate the running and starting wattage requirements for the devices you will be powering,
follow these steps:
1. Make a list of all electrical devices you will be powering at the same time with the generator.
2. List the greater of the running or starting wattage next to each device as obtained from the
devices’ nameplate or Table 1 . If only the running wattage for a device with an electric motor is
known, the starting wattage can be estimated to be at least 3 times the running wattage.
3. Add the wattages for all devices on your list. This total must be lower than the continuous output
rating of your generator.
Example:
Device to be Powered Greater of Starting/Running
Wattage
Light bulb 75 W
Refrigerator – 18 cu. ft. 1600 W
Microwave 700 W
Window AC 1800 W
Sump pump (1/3 HP) 2100 W
Total 6275W
In this example, the generator must have a continuous output of at least 6275 W in order to power
all of the devices simultaneously.
You can increase the number of devices your generator can power by staggering the load on the
generator. For example, you could alternately power your refrigerator and air conditioner for limited
periods of time -- powering only one of the devices at a time and never powering both at the same time.
