So I have an old main panel I don't want to touch - yet? Customer is cash poor with baby due... But will be changed in near future.
Anyway, would you call this a tap?
All conductors are #2 cu THWN/THHN for the service and feeder conductors- 100A main in backfed old style CH breaker, with 3 other 20A circuits, and a 60' feeder off the lugs to another (new) sub on (E) feeder.
420.2 describes a tap as such:
Tap Conductors. As used in this article, a tap conductor is defined as a conductor, other than a service conductor, that has overcurrent protection ahead of its point of supply that exceeds the value permitted for similar conductors that are protected as described elsewhere in 240.4.
If the service conductors are 100A, so is the panel MCOP, and the feeder is rated for >100A, not <, how would this be a "TAP"?
Inpector wants an OCPD for the feeder alone. Calling into play the TAP rules.... If the feeder conductors were rated for 80A, I could see that....
What say you?
