Two types of convenience outlets are offered on 50LC models:
non unit-powered and unit-powered. Both types provide a
125-v GFCI (ground-fault circuit interrupter) duplex receptacle
rated at 15A behind a hinged waterproof access cover, located
on the end panel of the unit. See Fig. 52.

Installing Weatherproof Cover
A weatherproof while-in-use cover for the factory-installed con -
venience outlets is now required by UL standards. This cover
cannot be factory-mounted due its depth; it must be installed at
unit installation. For shipment, the convenience outlet is covered
with a blank cover plate.
The weatherproof cover kit is shipped in the unit’s control box.
The kit includes the hinged cover, a backing plate, and gasket.
1. Remove the blank cover plate at the convenience outlet;
discard the blank cover.
2. Loosen the two screws at the GFCI duplex outlet, until
approximately
1/2
-in. (13 mm) under screw heads is
exposed. Press the gasket over the screw heads.
3. Slip the backing plate over the screw heads at the keyhole
slots and align with the gasket; tighten the two screws
until snug (do not over-tighten).
4. Mount the weatherproof cover to the backing plate as
shown in Fig. 53.
5. Remove two slot fillers in the bottom of the cover to per -
mit service tool cords to exit the cover.
6. Check for full closing and latching.

Non-Unit Powered Convenience Outlet
This type requires the field installation of a general-purpose 125-v
15A 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 125v power supply conductors into the bottom of the utility
box containing the duplex receptacle.
Unit-Powered Convenience Outlet
A unit-mounted transformer is factory-installed to step down the
main power supply voltage to the unit to 115v at the duplex recep -
tacle. This option also includes a manual switch with fuse, located
in a utility box and mounted on a bracket behind the convenience
outlet; access is through the unit’s control box access panel. See
Fig. 52.
The primary leads to the convenience outlet transformer are not
factory-connected. If local codes permit, the transformer primary
leads can be connected at the line-side terminals on the unit-
mounted non-fused disconnect or HACR breaker switch; this will
provide service power to the unit when the unit disconnect switch
or HACR switch is open. Other connection methods will result in
the convenience outlet circuit being de-energized when the unit
disconnect or HACR switch is open. See Fig. 54.
WARNING
PERSONAL INJURY HAZARD
