* 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:
500 kcmil for all unit sizes 050-071; all voltages
For units with optional non-fused disconnect:
350 kcmil for unit sizes 050-071, 208/230-3-60 voltages.
3/0 AWG for all other 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.
