Ground Input Lug
(all models)
1. With the conduit in place, make sure the upstream source of power is off or isolated, then
pull the incoming power cables, phase, neutral and ground, to the panel. Refer to the wire
specification chart above for wire, strip length, torque and tool specification.
2. Strip back the cable jackets to the length indicated in the wire specification chart,
depending on the connection.
3. Terminate the ground cable to the ground lug located on the top left or top right side of
the panel.
Using a 5/16 inch hex key, tighten the lug to the torque indicated above.
•
4. Terminate the neutral cable to the neutral lug located on the right side of the panel.
Using a 5/16 inch hex key, tighten the lug to the torque indicated above.
•
5. Terminate the phase cables to the main lugs or main circuit breaker (if installed). Using the
appropriate sized Allen wrench, tighten the lug to the torque indicated above.
