Non-Powered Convenience Outlet
This type requires the field installation of a general-pur-
pose 125v 15A circuit powered from a source elsewhere in
the building. Observe national and local codes when select-
ing wire size, fuse or breaker requirements, and disconnect
switch size and location. Route 125v power supply conduc-
tors 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 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. 20.
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 trans-
former primary leads can be connected at the line-side ter-
minals on the unit-mounted non-fused disconnect switch;
this will provide service power to the unit when the unit dis-
connect switch is open. Other connection methods will re-
sult in the convenience outlet circuit being de-energized
when the unit disconnect switch is open. See Fig. 23.
Using Unit-Mounted Convenience Outlets
Units with unit-mounted convenience outlet circuits will
often require that two disconnects be opened to de-energize
all power to the unit. Treat all units as electrically energized
until the convenience outlet power is also checked and de-
energization is confirmed. Observe National Electrical
Code Article 210, Branch Circuits, for use of convenience
outlets.

Fuse On Power Type
The factory fuse is a Bussman "Fusetron" T-15, non-re-
newable screw-in (Edison base) type plug fuse.
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 in-
tended 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. Convenience
outlet usage rating:
• Continuous usage: 8 amps maximum
• Intermittent usage: Up to 15 amps maximum for up to 2
hours maximum
See Fig. 24.
Test the GFCI receptacle by pressing the TEST button on
the face of the receptacle to trip and open the receptacle.
Check for proper grounding wires and power line phasing if
the GFCI receptacle does not trip as required. Press the RE-
SET button to clear the tripped condition.
