Notes:
1. MCA: Minimum Circuit Ampacity is 125% of the largest compressor RLA, plus 100% of the other compressor(s) RLA, plus the sum of the condenser fan FLA, plus any other
load rated at 1 AMP or more
2. Maximum Fuse Size: 225% of the largest compressor RLA, plus 100% of the other compressor(s) RLA, plus the sum of the condenser fan FLA, plus any other load rated at 1
AMP or more
3. Recommended Dual Element Fuse Size: 150% of the largest compressor RLA plus 100% of the other compressor(s) RLA plus the sum of the condenser fan FLA plus any
other load rated at 1 AMP or more.
4. RLA: Rated in accordance with UL standard 1995.
5. Local codes may take precedence.
6. All units are across the line starting. Compressors will never start simultaneously.
7. One 115/60/1, 15 AMP jobsite provided power connection is required to operate the evaporator heat tape.
Load Definitions
LOAD1 = Current of the largest motor —
compressor or fan motor
LOAD2 = Sum of the currents of all
remaining motors
LOAD3 = Current of electric heaters
LOAD4 = Any other load rated at 1 amp
or more
MCA = (1.25 x LOAD1) + LOAD2 +
LOAD4
MOP = (2.25 x LOAD1) + LOAD2 +
LOAD4
Electrical
Data - 60 HZ
Select a fuse rating equal to the MOP
value. If the MOP value does not equal a
standard fuse size as listed in NEC 240-6,
select the next lower standard fuse
rating.
NOTE: If selected MOP is less than the
MCA, then reselect the lowest standard
maximum fuse size which is equal to or
larger than the MCA, provided the
reselected fuse size does not exceed 800
amps.
RDE = (1.5 x LOAD1) + LOAD2 +
LOAD4
Select a fuse rating equal to the RDE
value. If the RDE value does not equal a
standard fuse size as listed in NEC 240-6,
select the next higher standard fuse
rating.
NOTE: If the selected RDE is greater than
the selected MOP value, then reselect
the RDE value to equal the MOP value.
DSS = 1.5 x (LOAD1 + LOAD2 +
LOAD3 + LOAD4)
Select a disconnect switch size equal to
or larger than the DSS value calculated.
