Trying to interpret a utility line diagram revision. For a backfed AC module system they want: "Clearly label 89L disconnect , 52-IT circuit breaker"
I have only seen ANSI Device 89-L labels on AC disconnects, but I assume it also applies to the backfed breaker.. What I can't figure out is if the branch breakers in the PV dedicated panel qualify as 52-IT and need to be labeled as such. Any thoughts? Haven't dealt much with this utility yet (ConEd).
