1.
Determining the Minimum Current
Ampacity (MCA),
NOTE: The data in Table-
1 & 2 can be used for MCA and MOP if the
equipment is standard with no variations, i.e.
additional process pump wired to the chiller.
Additional pumps will increase power
consumption and will nullify the data on table
1 & 2.
When available, refer to the
equipment data specification sheet
(this will
be located on the outside of the single point
electrical enclosure.
2. Refer to Table 2. Consider the Minimum
Circuit Ampacity (MCA) to determine the
appropriate wire size.
NOTES:
A. All fuses should follow UL 248-12 which
indicates that all fuses should be class R rated
for either, 250V or 600V and current ratings
under 600 Ampere.
B. If the wire pull exceeds 100 ft. Table 3 shall
not be used to select wire. Proper voltage drop
calculation should be considered and the wire
size must be adjusted per the adjusted ampere
rating.
Electrical Installation and Wire Sizing
Field Connections and Installations:
There are two main electrical field
connections that must be made.
(1)
Tank Temperature Sensor.
Connect
the factory supplied tank temperature
sensor into the fluid tank.
(2) The high voltage line connection.
230-460/3ph/60hz input voltages, refer to
the unit data sheet for MCA and MOP,
determine the minimum wire size using
Table 3.
