Appliance Loads

Marine generator sets are often used to furnish AC for
appliances such as TV, stereo, electric water heaters,
etc. With the exception of the resistance-type loads
such as the water heater, requirements for appliances
are usually low. Such loads must not, however, be
overlooked when figuring total requirements. Reserve
capacity should be available for anticipated appliance
loads to avoid overloading of a set. The average power
requirements of some common electrical appliances
are given in Figure 6-3.

Kilowatt Derating

Units are rated as listed below at 1.0 power factor.
Derate the listed rating by approximately 3.5% per 1000
ft. (300 m) when the unit is operated at altitudes of 500 ft.
(150 m) or more above sea level.
