CALIBRATOR 3964789 - Caterpillar

Load Connections
Perform the following checks to ensure proper operation of the power module.
Verify that the generator circuit breaker is "OPEN". Opening the breaker is to ensure that the unit is isolated.
Ensure that the bus system is in working condition. If any bus system components are loose or have shifted, resolve any problem before continuing.
Install a ground cable from the ground electrode for the site to the ground bus bar. Review the "National Electric Code" (NEC). Refer to sections 250-91(a), 250-92(a), 250-93 and/or 250-94 for further details. Refer to the NEC requirements for sizing the ground wire. When removing electrical cables, the ground wire must be the last cable removed.
Connect properly sized cables from each phase and the neutral bar to the load.
Ensure that all fasteners on the bus system are tight and secure. Refer to Table 1.

Ensure that cables are connected properly. Do not cross phases or alter phase rotation.
Ensure that the minimum electrical spacing has not been exceeded. If the spacing has changed, make the necessary adjustments prior to energizing the bus.
A cable sock is provided if using side access. The sock is used to prevent accidental access to the bus work when the access door is open. After attaching the load cables, pull the sock as far down the cables as possible. Secure the sock with the velcro straps that are provided.

Connect shore power and control wiring to the customer interconnect panel as required. Ensure that the wiring is routed away from the bus system.
