Wiring for Off-Grid Applications Using an AC Distribution Panel and an External Generator Disconnect

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 an AC distribution panel for the outputs and a 120 Vac generator for input. Wiring instructions are provided for making ground connections first (page 1–19), neutral connections second (page 1–20), and hot connections last (page 1–21).
