Generator Set Connections

The factory-installed wiring kit eliminates the need to
make field connections inside the generator set junction
box. The wiring kit includes a wiring harness and an AC
outlet mounted inside the generator set enclosure for
the battery charger and accessories. See Figure 2-13.
The wiring harness includes the engine start leads,
power leads to the AC outlet, and the emergency power
leads. The leads exit the generator set in 1 1/4 inch
conduit with liquid-tight connections. Cut a 2-inch hole
through the building wall to bring the PVC end of the
conduit into the building. Secure the PVC assembly to
the wall using the clamp provided. Seal the gap around
the conduit with caulk. Use duct seal inside the conduit if
desired.
