Running an Appliance on a Generator

The use of an auxiliary power generator is an individual decision. There are some things to keep in mind when considering use of an auxiliary generator. Voltage and cycles are critical for proper operation of appliances. US power standards are 60 hz, 120v ac.
  • Refrigerators, freezers and air conditioners place a high demand upon the power source during starting. If the voltage is not stable tripping could occur during attempted start ups.
  • Any variation in cycles could cause electric clocks to go fast or slow. Generators should be voltage regulated and surge protected for the appliances.
  • Some generators may not be recommended by the generator manufacturer for use with major appliances.
  • GE does not recommend specific generators, only approximate sizes.
It is suggested that anyone interested in generator compatibility with a major appliance check the specifications with the generator manufacturers. Below is the approximate size generator needed for each appliance category:


APPLIANCE GENERATOR SIZE
REFRIGERATORS 3000 - 4500 WATTS
FREEZERS 3000 - 4500 WATTS
RANGES 26,000 - 40,000 WATTS
RANGES (GAS) 1500 - 2500 WATTS
MICROWAVES 3000 - 4500 WATTS
DISHWASHERS 3000 - 4500 WATTS
WASHERS 2000 - 3000 WATTS
DRYERS 11000 - 17000 WATTS
DRYERS (GAS) 1500 - 2500 WATTS
RAC (240V) 9000 - 13500 WATTS
RAC (120V) 3000 - 4500 WATTS


NOTE: AMPS X VOLTS = WATTS
