CONVENIENCE OUTLETS
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal
injury or death.
Units with convenience outlet circuits may use
multiple disconnects. Check convenience outlet for
power status before opening unit for service. Locate
its disconnect switch, if appropriate, and open it.
Tag--out this switch, if necessary.

WARNING
Two types of convenience outlets are offered on 48TC
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. 16.)

Fig. 16 -- Convenience Outlet Location
Non--Powered Type
This type
requires the
field installation of a
general--purpose 125--volt 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 duplex 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. 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 heaters 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).
