*
Supply Range — Units are suita
b
le for use on electrical systems where
voltage supplied to the unit terminals is not
b
elow or a
b
ove the listed
range limits.
NOTES:
1. All units have one field power terminal
b
lock.
2. Maximum incoming wire size is as follows:
For units with terminal
b
lock:
350 kcmil for unit sizes 030-045;
208/230-3-60 voltages.
2/0 for unit sizes 016-045; all other voltages.
For units with optional non-fused disconnect:
350 kcmil for unit sizes:
030-045; 208/230-3-60 voltages.
045; 380-3-60 voltage.
3/0 AWG for unit sizes:
016,020; 208/230-3-60 voltages.
020-040; 380-3-60 voltage.
030-045; 460-3-60, 380/415-3-50 and 575-3-60 voltages.
2 AWG for unit sizes:
016: 380-3-60 voltage.
016,020; 460-3-60, 380/415-3-50 and 575-3-60 voltages.
For units with optional fused disconnect:
6 AWG to 10 AWG for all voltages.
3. Additional control circuit power is not re
q
uired.
4. Any field modification of factory wiring must
b
e in compliance with
all applica
b
le codes. Field-installed power wires must
b
e rated
75°C minimum.
5. Use copper conductors only.
6. Control circuit power supply is 24-v single phase. Control power is
supplied
b
y the factory-installed control transformer.
7. The MOCP of the electrical distri
b
ution panel is calculated as
follows:
First, calculate the MOCP of each individual chiller. MOCP =
2.25 (Largest RLA) + Sum of the other RLAs. Sum the MOCPs
of each individual chiller. This is the MOCP of the electrical dis-
tri
b
ution panel associated with this
b
ank of chillers. Select the
next size down fuse from this value.
The recommended fuse size in amps (RFA) is calculated as fol-
lows: RFA = 1.50
*
(largest RLA) + (Smallest RLA) for the given
b
ank of chillers.
8. The MCA of the electrical distri
b
ution panel is calculated as
follows:
First, calculate the MCA of each individual chiller. MCA = 1.25
(Largest RLA) + sum of the other RLAs. Sum the MCAs of
each individual chiller. This is the MCA of the electrical distri
b
u-
tion panel associated with this
b
ank of chillers.
