WARNING
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. Lock-out and tag-out this switch, if
necessary.
Two types of convenience outlets are offered on the 50LC 08-12
units: 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 pan-
el beneath the control box. See Fig. 38.

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 and con-
duit requirements, 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 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 panel beneath the control box.
See Fig. 38.
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 the unit-mounted non-
fused disconnect switch; this will provide service power to the unit
when the unit disconnect switch is open. Other connection meth-
ods will result in the convenience outlet circuit being de-energized
when the unit disconnect switch is open. See Fig. 39. On a unit
without a unit-mounted disconnect, connect the source leads to the
main terminal block (TB1).
If the convenience outlet transformer is connected to the line side
of a field disconnect, the conduit provided with the unit must be
used to protect the wire as they are routed from the transformer to
the field disconnect. The end of the conduit with the straight con-
nector attaches to the field disconnect. The other end does not
need to connect to the transformer; however, the conduit must be
routed so that all wiring is either in the conduit or behind the ac-
cess panel.
