Non-powered 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 bot-
tom of the utility box containing the duplex receptacle.
Unit-powered type — A unit-mounted transformer which is fac-
tory-installed to step-down 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. 48 and 49.
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 non-fused disconnect switch is open. See Fig. 51.
On a unit without a unit-mounted non-fused disconnect, connect
the source leads to the main terminal block (TB1 for sizes 08-14,
TB3 for size 16).
Fig. 51 — Powered Convenience Outlet Wiring
On size 16 units, if the convenience outlet transformer is con-
nected to the line side of a field disconnect, the conduit provided
with the unit must be used to protect the wire as they are routed
from the transformer to the field disconnect. The end of the con-
duit with the straight connector attaches to the field disconnect.
The other end does not need to connect to the transformer; howev-
er, the conduit must be routed so that all wiring is either in the con-
duit or behind the access panel.
On size 16 units, if the convenience outlet transformer is con-
nected to the line side of the factory disconnect option, route the
wires through the web bushing located on the bottom of the dis-
connect box. For the load side wiring to the factory option discon-
nect, route the wires through the hole on the right side of the dis-
connect. Be sure to create a drip loop at least 6 in. long.
ALL UNITS — 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.
Unit-mounted convenience outlets — Outlets 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-renewable screw-in (Edison base) type plug fuse. See
Fig. 52 for maximum continuous use amp limitations.

FACTORY-OPTION THRU-BASE CONNECTIONS
(ELECTRICAL CONNECTIONS) (SIZE 08-14) —
This
service connection kit consists of a 1 /
2
-in. NPT gas adapter fit-
ting (brass), a 1 /
2
in. electrical bulkhead connector and a 3 /
4
-in.
electrical bulkhead connector, all factory-installed in the em-
bossed (raised) section of the unit basepan in the condenser
section. The 3 /
4
in. bulkhead connector enables the low-voltage
control wires to pass through the basepan. The 1 /
2
in. electrical
bulkhead connector allows the high-voltage power wires to
pass through the basepan. See Fig. 26.
Check tightness of connector lock nuts before connecting elec-
trical conduits.
Field-supplied and field-installed liquid tight conduit connec-
tors and conduit may be attached to the connectors on the basepan.
Pull correctly rated high voltage and through appropriate con-
duits. Connect the power conduit to the internal disconnect (if unit
is so equipped) or to the external disconnect (through unit side
panel). A hole must be field cut in the main control box bottom on
the left side so the 24-v control connections can be made. Connect
the control power conduit to the unit control box at this hole.
Units Without Thru-Base Connections
1. Install power wiring conduit through side panel openings.
Install conduit between disconnect and control box.
2. Install power lines to terminal connections as shown in
Fig. 51.
Voltage to compressor terminals during operation must be
within voltage range indicated on unit nameplate. On 3-phase
units, voltages between phases must be balanced within 2% and
the current within 10%. Use the formula shown on page 28 to de-
termine the percent of voltage imbalance. Operation on improper
line voltage or excessive phase imbalance constitutes abuse and
may cause damage to electrical components. Such operation
would invalidate any applicable Bryant warranty.
