Wet In Use Convenience Outlet Cover; Non-Powered Type; Unit-Powered Type - Carrier WeatherExpert 48LC 14 Series Service And Maintenance Instructions

Two types of convenience outlets are offered on 48LC models:
non-powered and unit-powered. Both types provide a 125-volt
GFCI (ground-fault circuit-interrupter) duplex receptacle rated at
15-A behind a hinged waterproof access cover, located on the end
panel of the unit. (See Fig. 15.)

Wet in Use Convenience Outlet Cover

The unit has a "wet in use" convenience outlet cover that must be
installed on panel containing the convenience outlet. This cover
provides protection against moisture entering the GFCI receptacle.
This cover is placed in the unit control box during shipment. See
Fig. 16.

Non-Powered Type

This type requires the field installation of a general-purpose 125-v
15-A circuit powered from a source elsewhere in the building. Ob-
serve national and local codes when selecting wire size, fuse or
breaker requirements and disconnect switch size and location.
Route 125-v power supply conductors into the bottom of the utili-
ty box containing the duplex receptacle.

Unit-Powered Type

A unit-mounted transformer is factory-installed to stepdown the
main power supply voltage to the unit to 115-v at the duplex re-
ceptacle. This option also includes a manual switch with fuse, lo-
cated in a utility box and mounted on a bracket behind the conve-
nience outlet; access is through the unit's control box access panel.

The primary leads to the convenience outlet transformer are not
factory-connected. Selection of primary power source is a custom-
er option. If local codes permit, the transformer primary leads can
be connected at the line-side terminals on a unit-mounted non-
fused disconnect or circuit-breaker switch; this will provide ser-
vice power to the unit when the unit disconnect switch or circuit-
breaker is open. Other connection methods will result in the con-
venience outlet circuit being de-energized when the unit discon-
nect or circuit-breaker is open. (See Fig. 17.)

DUTY CYCLE
The unit-powered convenience outlet has a duty cycle limitation.
The transformer is intended to provide power on an intermittent
basis for service tools, lamps, etc; it is not intended to provide
15 amps loading for continuous duty loads (such as electric heat-
ers for overnight use). Observe a 50% limit on circuit loading
above 8 amps (i.e., limit loads exceeding 8 amps to 30 minutes of
operation every hour).
