Table 8 — 30XA140-500 Electrical Data, Dual Point (High Ambient Option) (cont)
LEGEND
NOTES:
1. Units are suitable for use on electrical systems where voltage supplied to the unit
terminals is not below or above the listed minimum and maximum limits. Maximum
allowable phase imbalance is: voltage, 2%; amps 10%.
2. Cooler heater is wired into the control circuit so it is always operable as long as the
control power supply disconnect is on, even if any safety device is open.
3. For MCA that is less than or equal to 380 amps, 3 conductors are required.
For MCA between 381-760 amps, 6 conductors are required.
For MCA between 761-1140 amps, 9 conductors are required.
For MCA between 1141-1520 amps, 12 conductors are required.
Calculation of conductors required is based on 75 C copper wire.
4. Wiring for main field supply must be rated 75 C minimum. Use copper for all units.
a. Incoming wire size range for the terminal block is no. 4 AWG (American Wire Gage)
to 500 kcmil.
b. Incoming wire size range of non-fused disconnect with MCA up to 599.9 amps is
3/0 to 500 kcmil.
c. Incoming wire size range of non-fused disconnect with MCA from 600 to 799.9 amps
is 1/0 to 500 kcmil.
d. Incoming wire size range of non-fused disconnect with MCA from 800 to 1199.9 amps
is 250 kcmil to 500 kcmil.
5. Data provided circuit 1/circuit 2 where there are two circuits.
