GenerLink™
The wattages presented in this table are estimates. The actual wattage required for your appliances can be calculated. Remember that 1kW = 1000 watts, 2kW = 2000 watts, etc.
Running Watts = Volts x Amps
Rule of thumb: allow 2kW/Horse Power for appliances with motors. Some motors can require up to 3 times the running wattage to start.
Always use starting wattage when calculating electrical load requirements for your generator. Select the appliances you want to operate and add the starting wattages together to determine if they can all be operated at the same time without exceeding the limits of your generator. Remember that circuit breakers usually control more than one appliance.
