b) Installing Three-Phase AC Output Cables
Figure 1-2-3 Figure 1-2-4 Figure 1-2-5
The generator set may be shipped without aircraft cables. Output cables connect to the load
contactors, which are located at rear of unit. (See Figure 1-2-3)
The conductor size recommended for AC output cables is 2/0 AWG. Use No. 12 AWG for E and F
terminals. Lugs require a minimum 3/8-inch diameter hole to fit into the output contactor. (See
Figure 1-2-4) The E and F wires should be fitted with 16 gauge forks or into a double ferrule and
then inserted into the normally open auxiliary contact block attached to the side of the output
contactor. (See Figure 1-2-5)
AC output cables installation:
1) Remove canopy. (While not necessary, it greatly simplifies the process.)
2) Loosen screws on cable clamps.
3) Route cables through hole in cable tray, through cable clamps up to load side of load
contactor(s).
4) Connect phase cable terminal lugs to appropriate terminal studs on contactor(s): cable lug A
to terminal stud A, B to B, and C to C.
5) Connect cable’s neutral terminal lug securely to neutral (ground) stud on power module
assembly. (See Figure 1-2-4)
6) Connect E and F cables into the auxiliary contact block on side of output contactor.
7) Tighten clamp screws securely, but avoid damage to cable insulation.
8) Replace canopy.
