Ac Load Lead Connections - Kohler 4CKM Operation And Installation Manual

AC Load Lead Connections

Each set has four color-coded load leads and a
connector for attaching flexible conduit from the
generator end bracket to the load terminal junction box
typically installed in the compartment. The black leads
(L1 and L2) are hot, the white lead (L0) is neutral, and
the green lead is the hazard ground.
Route load leads through flexible conduit and keep
circuit away from the generator set, specifically fuel and
exhaust system components.
Figure 6-25 represents position and dimensions for
typical junction box installation. A junction box should be
installed to make it accessible for inspection and
service.
Suggested Minimum Dimensions
1. Box for field connection should be accessible after installation for
inspection and servicing

The AC load lead L0 (white) is always the neutral lead on
Kohler generator sets— make sure the neutral of the AC
circuit in the vehicle is connected to lead L0 (white). If
equipment ground-type plugs and receptacles (3
pronged) are used in the vehicle, the green wire must be
connected to the U-shaped pin. On vehicles which also
have provisions for using an outside AC power source,
the neutral as well as the hot (black) leads must be
completely isolated from the generator set when power
is switched to the out-side source. See Figure 6-26.

A double-pole, double-throw transfer switch rated for
the calculated load of the RV must be used to transfer
the load from one source to the other. A ground-fault
circuit interrupter should be installed in the wiring
system to protect all branch circuits.
