Wiring for Off-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 off-grid application using additional circuit breakers in the ACCB for the outputs and a 120 Vac generator for input. This diagram also includes the use of a generator disconnect breaker in the ACCB. Wiring instructions are provided for making ground connections first (page 1–27), neutral connections second (page 1–28), and hot connections last (page 1–29).
