Units Without Factory- - Installed
Non- - Fused Disconnect —
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. 16 and the unit
label diagram for power wiring connections to the unit
power terminal blocks and equipment ground. Maximum
C12284
wire size is #2 ga AWG (copper only) per pole on
contactors.
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.
All field wiring must comply with the NEC and local
requirements.
All units except 208/230-v units are factory wired for the
voltage shown on the nameplate. If the 208/230-v unit is
to be connected to a 208-v power supply, the control
transformer must be rewired by moving the black wire
1
with the
/
-in. female spade connector from the 230- - v
4
connection and moving it to the 200-v
terminal on the primary side of the transformer. Refer to
unit label diagram for additional information. Field power
wires will be connected 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 —
!
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal
injury or death.
Units with convenience outlet circuits may use
multiple disconnects. Check convenience outlet for
power status before opening unit for service. Locate
its disconnect switch, if appropriate, and open it.
Lock- - out and tag- - out this switch, if necessary.
Two types of convenience outlets are offered on 50KCQ
models: Non- - powered and unit- - powered. Both types
provide
a
circuit- - interrupter) duplex receptacle rated at 15- - A
behind a hinged waterproof access cover, located on the
end panel of the unit. See Fig. 20.
NOTE:
Unit powered convenience outlets are not
C12279
available as factory installed options for size 04- - 06 single
phase (- - 3 voltage code) models.
