3.Wiring for main field supply must be rated 75 C. Use copper conductors only.

a.Incoming wire size range for terminal block with MCA (minimum circuit amps) up to 175 amps is 14 AWG (American Wire Gage) to 2/0.

b. Incoming wire size range for terminal block with MCA from 175.1 amps to 420 amps is 2 AWG to 600 kcmil.

c. Incoming wire size range for non-fused disconnect with MCA up to 100 amps is 14 AWG to 1/0.

d. Incoming wire size range for non-fused disconnect with MCA from

100.1amp to 200 amps is 6 AWG to 350 kcmil.

e. Incoming wire size range for non-fused disconnect with MCA from

200.1amp to 450 amps is 3/0 to 500 kcmil.

4.Refer to certified dimensional drawings for exact locations of the main power and control power entrance locations.
