Wiring for Off-Grid Applications using an AC Distribution 
Panel and an Internal 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. This diagram also includes the use of a generator 
disconnect breaker in the ACCB. Wiring instructions are provided for 
making ground connections first (

page 1–23

), neutral connections second 

(

page 1–24

), and hot connections last (

page 1–25

).
