Wiring for On-Grid Applications Using Additional Circuit Breakers in the ACCB Only

The following diagram shows the complete wiring diagram for wiring the ACCB and Sine Wave Plus Inverter inputs and outputs in an on-grid application using an AC distribution panel for the outputs and a 120 Vac generator for input. This diagram also uses an internal generator disconnect breaker in the ACCB. Wiring instructions are provided for making ground connections first (page 1–35), neutral connections second (page 1–36), and hot connections last (page 1–37).

WARNING: Shock Hazard

Ensure that all AC and DC power is not “live” before proceeding.

Important: The inverter bypass circuit breaker can only be wired directly to, and work with, a single AC source. In a system that has multiple AC sources, you must decide which AC source will be wired through the inverter bypass circuit breaker and which will not. The following illustrations assume that the primary AC input source will be the utility grid.
