We have an old Bryant panel, so we are using a listed Cutler Hammer circuit breaker to back feed the panel from the inverter output.
The breaker handle is labelled On/I and Off/O.
Article 690.10(E) states that "Circuit breakers that are marked "Line" and "Load" shall not be backfed".
The question is, does I/O mean the same thing as Line/Load?
If I read the code verbatim, the breaker is not specifically labelled Line / Load and should be able to be used. I can however see the inspector saying the input comes from the grid on the "I" side and input from the inverter enters the "O" side and might have an issue with it.
Any thoughts?
