enclosure located under the main control box. The manual
switch handle is accessible through an opening in the access
panel. Discard the factory test leads (see Fig. 43). The factory
disconnect is an 80A disconnect.

Convenience Outlets
Two types of convenience outlets are offered on the 50TC-
D16: non-powered and unit-powered. Both types provide a
125-volt GFCI (ground-fault circuit-interrupter) duplex recep-
tacle rated at 15-A behind a hinged waterproof access cover,
located on the panel beneath the control box. See Fig. 44.
Fig. 44 — 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 and conduit requirements, fuse
or breaker requirements and disconnect switch size and loca-
tion. 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 panel beneath the control box. See Fig. 44.
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 the unit-
mounted non-fused disconnect switch; this will provide service
power to the unit when the unit disconnect switch is open.
Other connection methods will result in the convenience outlet
circuit being de-energized when the unit disconnect switch is
open. See Fig. 46. On a unit without a unit-mounted discon-
nect, 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 connector attaches to the field disconnect. The
other end does not need to connect to the transformer; how-
ever, the conduit must be routed so that all wiring is either in
the conduit or behind the access panel.
If the convenience outlet transformer is connected to the line
side of the factory disconnect option, route the wires through
the web bushing located on the bottom of the disconnect box.
For the load side wiring to the factory option disconnect, route
the wires through the hole on the right side of the disconnect.
Be sure to create a drip loop at least 6 in. long.
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.
