LEGEND FOR TABLES 4A AND 4B
NOTES FOR TABLES 4A AND 4B
ICF
— Maximum instantaneous current flow during starting. For these
single-compressor units, ICF is the compressor LRA.
kcmil — Thousand circular mils
LRA
— Locked rotor amps. First value is for part-wind start. Larger value
is the full LRA.
MCA
— Minimum circuit amps (for wire sizing). Complies with NEC,
Section 430-24.
MFA
— Maximum fuse amps (225% of compressor RLA). Size down to
the next standard fuse size.
MTA
— Must-trip amps (compressor circuit breaker).
NEC
— National Electrical Code (U.S.A.)
PW
— Part wind
Rec Fuse — Recommended dual element fuse amps (150% of
compressor RLA). Size up to the next standard fuse size.
RLA
— Rated load amps
XL
— Across the line
*Supply Range — Units are suitable for use on electrical systems where volt-
age supplied to the unit terminals is not below or above the listed range limits.
†Contact your local Carrier representative for part-wind details.
**Compressor no. 1/Compressor no. 2.
1. All units have one field power terminal block.
2. Maximum incoming wire size:
a. 350 kcmil for unit sizes 040-060; 208/230-3-60, 230-3-50, and 400-3-50
voltages.
b. 2/0 for all other unit sizes; all voltages.
3. Any field modification of factory wiring must be in compliance with all ap-
plicable codes. Field-installed power wires must be rated 75 C minimum.
4. Use copper, copper-clad aluminum, or aluminum conductors for field wiring.
5. For all 30HW units, control circuit power supply is 115-v single phase for 50-
and 60-Hz units. Control power is supplied by the factory-installed control
transformer. Additional control circuit power is not required for 30HW units.
6. Across-the-line start is standard on all units. Part-wind start is available as
a factory-installed option on 025-060 sizes (not available on 018 size; spe-
cial order option on 30HK,HL units).
7. For all 30HK,HL units, control circuit MCA is 7.2, and control circuit MFA is
15. For 30HK,HL 60 Hz units, a separately-fused (15 amp maximum) 115 v,
single-phase, 60 Hz, power supply or accessory transformer is required.
For 30HK,HL 50 Hz units, a field-supplied, separately fused (15 amps maxi-
mum), 230 v, single-phase, 50 Hz power supply is required.
