CONVENIENCE OUTLETS
Two types of convenience outlets are offered on 50LC models:
non-powered and unit-powered. Both types provide a 125-v
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. 16.)

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. 17.

Duty Cycle
The unit-powered convenience outlet has a duty cycle limita-
tion. The transformer is intended to provide power on an inter-
mittent basis for service tools, lamps, etc. It is not intended to
provide 15 amps loading for continuous duty loads (such as
electric heaters for overnight use). Observe a 50% limit on cir-
cuit loading above 8 amps (i.e., limit loads exceeding 8 amps
to 30 minutes of operation every hour).
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. Observe 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 utility 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 du-
plex receptacle. 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. 16.)
The primary leads to the convenience outlet transformer are
not factory-connected. Selection of primary power source is a
customer 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 service power to the unit when the unit disconnect
switch or circuit-breaker is open. Other connection methods
will result in the convenience outlet circuit being de-energized
when the unit disconnect or circuit-breaker is open. (See
Fig. 18.)
WARNING
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal inju-
ry or death.
Units with convenience outlet circuits may use multiple
disconnects. Check convenience outlet for power status be-
fore opening unit for service. Locate its disconnect switch,
if appropriate, and open it. Lock-out and tag-out this
switch, if necessary.
