Load Management Basics
To understand how battery chargers, automatic generator start systems and other
baseloads affect your generator, you need to be aware of three things:
1) Your generator’s power capability
2) How to manage electrical loads
3) Battery charging times
Determining Your Generator’s
Power Capability
To determine what your generator can power, use the chart on the opposite page
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
Onan generator or your RV’s circuit breaker rating.
