Customer Convenience Outlets; Derating For Altitude - Magnum MMG25FHZ Operating Manual

CUSTOMER CONVENIENCE OUTLETS

The generator is equipped with four convenience outlets. The large outlets
are 240/120 VAC twist-lock receptacles rated at 50A each. The smaller
outlets are 120 VAC duplex receptacles rated at 20A each with ground fault
interrupt (GFCI) protection. These receptacles are not routed through the
main circuit breaker. Each receptacle has its own circuit breaker, located
directly above the receptacle panel, with the breaker sized to the maximum
rating of the corresponding outlet.
Power to the outlets is available any time the generator is
running, EVEN IF THE MAIN CIRCUIT BREAKER IS OFF
"O". MAKE SURE THAT ANY EQUIPMENT CONNECTED
TO THE CONVENIENCE OUTLETS IS TURNED OFF
BEFORE TURNING THE BREAKERS ON. Make sure that
the voltage selector switch is in the proper position and that
the output voltage is correct for the equipment that is
connected to the outlets. Improper voltage may cause
equipment damage or malfunction.
Note: When the voltage selector switch is in position for 480/277V 3Ø,
voltage at the two GFCI duplex convenience outlets is 139 Volts, and the
voltage at the two twist-lock outlets is 240/130 Volts. When the voltage
selector switch is in position for 208/120V 3Ø, voltage at the two twist-lock
outlets and the two GFCI duplex convenience outlets is 208/120 Volts.

DERATING FOR ALTITUDE

All generator sets are subject to derating for altitude and temperature; this will reduce the available power for operation
of tools and accessories connected to the auxiliary outlets. Typical reductions in performance are 2-4% for every
1000 ft. (305 meters) of elevation and 1% per 10º F (3-5º C) increase in ambient air temperature over 72º F (22.2º C).
