Non-Powered Convenience Outlet

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, fuse or breaker require-

ments 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 Convenience Outlet

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. 21.

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

disconnect; this will provide service power to the unit

when the unit disconnect switch is open. Other connec-

tion methods will result in the convenience outlet circuit

being de-energized when the unit disconnect is open.

See Fig. 24.

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 un-

til 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.
