TP-5606 6/023-20 Scheduled Maintenance
Wattage Requirements
If the rated capacity of the generator is exceeded, the
circuit breaker(s) located in the controller will trip to
protect the generator against damage. This could be
caused by a short in the AC circuit in the vehicle or
simply by having too many appliances (or tools) turned
on at the same time resulting in an overload condition. If
the circuit breaker(s) trip, the set may continue running
but there will be no AC output to the protected circuit.
Before resetting the circuit breaker(s), turn off some of
the appliances (or tools) and lights inside the vehicle to
bring the load down within the rated limits of the set. If
this is done and the circuit breaker(s) trips again after
being reset, a short circuit is indicated. In this event, turn
off the set and have a qualified electrician locate and
correct the cause of the short circuit.
The average wattage requirements of some common
RV/Mobile appliances/tools and motor loads are listed in
the following charts. Use these figures to calculate the
total load on this set to avoid the inconvenience of
having the circuit breaker trip due to overload. The
lighting load is easily determined by adding the wattage
rating of each bulb in the circuit. Check the nameplate
rating on motors and appliances in this vehicle for exact
wattage requirements.

NOTE
Motor-driven equipment generally takes 2 to 3 times the
listed running amperage or wattage to start the motor.
Always check the tool or motor nameplate to be sure.
