Engine Derating

All units are subject to derating for altitude and
temperature. Derating reduces the available power for
operating tools and accessories connected to the
receptacles. For every increase in 1,000 ft (305 m) of
elevation, engine performance for this unit typically drops
between 2–4%. Also, engine performance decreases
about 1% for every 10 °F (5.6 ºC) increase in ambient air
temperature over 72 ºF (22 ºC).

Customer Convenience
Receptacles (If Equipped)
See Figure 3-8. The unit may be equipped with one
120V, 20A, GFCI, duplex receptacle; for powering
accessories or tools.
Figure 3-8. Customer Convenience Receptacle
The receptacle, and a corresponding circuit breaker, are
located on the control panel. See
The receptacle is powered (available for use) when the
engine is running and the main circuit breaker is ON (I).

Load Limit and Overload

Lights on: Load limit = 1,100 W
•
Lights off: Load limit = 2.400 W
•
Drawing more than the load limit overloads the generator,
resulting in main circuit breaker trip. If the breaker trips,
switch off the lights and remove some load from the
receptacle.

Shutting Down the Unit

Shutting down the unit stops power to the customer
convenience receptacles (if equipped).

Removing Loads from Receptacles (If Equipped)

When shutting down the unit, remove loads from
receptacles as follows.
1. Notify personnel using unit-supplied power that
shutdown is pending.
2. Verify shutdown will not create hazards (by turning
off equipment that needs to remain running, such
as pumps and compressors).
3. Remove loads from receptacles.
Shutting Down the Unit
1. Remove all loads from receptacles.
