Section 6 Electrical Connections
6.1 — Generator Connections
NOTE: Control wiring may be already wired on pre-wired generators. If so, tighten the 5’ whip conduit inside of
the enclosure. If not, wiring must be in accordance with local jurisdiction and codes.
1. Remove the appropriate Main AC/Control Wiring Knock-out Plug from the back of the generator.
2. Install the conduit and Main AC and Control Wires between the generator and the transfer switch. See Figure 2.6
for knockout locations (verify specific transfer switch wiring/connections per model).
NOTE: These wiring connections may be present on pre-wired models.
NOTE: This wiring can be run in the same conduit if the appropriate insulation rated wire is used.
3. Seal the conduit at the generator and in compliance with any codes.
4. Strip the insulation from the ends of the wires. Do not remove excessive insulation.
5. To connect the control wires, push down on the spring loaded connection point with a flat head screwdriver, insert
wire and release.
NOTE: No wire insulation should be in the connection point, only bare wire.
