Non-Powered Convenience Outlet

This type requires the field installation of a general-purpose 125v

15A circuit powered from a source elsewhere in the building. Ob-

serve national and local codes when selecting wire size, fuse or

breaker requirements, and disconnect switch size and location.

Route 125v power supply conductors 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 recep-

tacle. 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. 24.

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. 26.

Using Unit-Mounted Convenience Outlets

Units with unit-mounted convenience outlet circuits will often re-

quire that two disconnects be opened to de-energize all power to

the unit. Treat all units as electrically energized until the conve-

nience outlet power is also checked and de-energization is con-

firmed. Observe National Electrical Code Article 210, Branch Cir-

cuits, for use of convenience outlets.

Fuse On Power Type

The factory fuse is a Bussman "Fusetron"

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 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. Convenience outlet usage rating:

•

Continuous usage: 8 amps maximum

•

Intermittent usage: Up to 15 amps maximum for up to

2 hours maximum

See Fig. 27.

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 RESET button to clear the

tripped condition.
