Determining your Generator's Power Capability
To determine what your generator can power, use the chart below to estimate the total combined watts of all the appliances, lamps, battery chargers, air conditioners and other electrical products you typically use at the same time. (All electrical appliances and lights are labeled with their power requirements expressed in watts or amps). You can use any number of appliances simultaneously, as long as their combined wattage doesn’t exceed the electrical output of your Cummins generator or your RV’s circuit breaker rating.
