Fig. 21 - - Weatherproof Cover Installation
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, 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 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
transformer primary leads can be connected at the
line- - side terminals on the unit- - mounted non- - fused
disconnect or HACR breaker switch; this will provide
service power to the unit when the unit disconnect switch
or HACR switch is open. Other connection methods will
result in the convenience outlet circuit being de- - energized
when the unit disconnect or HACR switch is open. See
Fig. 22.

type plug fuse.
NOTICE
Convenience Outlet Utilization
Maximum Continuous use : 8 Amps 24/7
Fig. 23 - - Convenience Outlet Utilization Notice Label
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.
