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. 26.
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. Oth-
er connection methods will result in the convenience outlet cir-
cuit being de-energized when the unit disconnect switch is
open. See Fig. 28.

Using unit-mounted convenience outlets
Units with unit-mounted convenience outlet circuits will often
require that two disconnects be opened to de-energize all pow-
er 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
1
“Fusetron” T-15, non-renew-
able screw-in (Edison base) type plug fuse.

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 re-
ceptacle does not trip as required. Press the RESET button to
clear the tripped condition.
