Please consider the following situation:
In the above situation, the 15A breaker is not protecting you. If the inverter can supply more than 15 amps, then the wires between panel and the inverter could be carrying up to 27 amps in the above diagram which would be over the rated amperage of the wires!
Connection Steps
- Turn off the main power circuit on panel!
- Turn off all circuits
- Ensure all 240v breakers are OFF. Any 240v breakers that feed sub panels can be kept on. Ensure 240v breakers on sub panels are OFF.
- Connect inverter to receptacle on desired phase. (Ideally a circuit not protected by a GFCI or arc fault breaker)
- Power on inverter
- Turn on critical circuits on panel.
