DISCONNECT OR HACR
When installing units, provide a disconnect switch per NEC
(National Electrical Code) of adequate size. Disconnect sizing
data is provided on the unit informative plate. Locate on unit
cabinet or within sight of the unit per national or local codes.
Do not cover unit informative plate if mounting the disconnect
on the unit cabinet.
ALL UNITS
All field wiring must comply with NEC and all local codes.
Size wire based on MCA (Minimum Circuit Amps) on the unit
informative plate. See Fig. 18 and the unit label diagram for
power wiring connections to the unit power terminal blocks
and equipment ground. Maximum wire size is #2ga AWG
(copper only) per pole on contactors, #2ga AWG (copper only)
per pole on optional disconnect or HACR, and 4/0 AWG
(copper only) per pole on terminal or fuse block on units with
single point box. See Fig. 18 and unit label diagram for field
power wiring connections.
Provide a ground fault and short circuit over-current protection
device (fuse or breaker) per NEC Article 440 (or local codes).
Refer to unit informative data plate for MOCP (Maximum
Over-Current Protection) device size.
NOTE: Units ordered with factory installed HACR do not need an
additional ground fault and short circuit over-current protective
device unless required by local codes.
All field wiring must comply with the NEC and local
requirements.
All units except 208/230v units are factory wired for the voltage
shown on the nameplate.
If the 208/230v unit is to be connected to
a 208v power supply, the control transformer must be rewired by
removing the black wire with the

-in. female spade connector
from the 230v connection and moving it to the 200v
1
/
4
-in. male
terminal on the primary side of the transformer. Refer to unit label
diagram for additional information. Field power wires will be
connected at line-side pressure lugs on the power terminal block
or at factory-installed option non-fused disconnect.
NOTE: Check all factory and field electrical connections for
tightness.
CONVENIENCE OUTLETS
Two types of convenience outlets are offered on 50JC models:
non-powered and unit-powered. Both types provide a 125-v
GFCI (ground-fault circuit interrupter) duplex receptacle rated
at 15A behind a hinged waterproof access cover, located on the
end panel of the unit. See Fig. 23.
Figure 24 shows the Convenience Outlet Utilization label
which is located below the convenience outlet.
