William, I would start with Article 240.21(B).

Subject: [RE-wrenches] Feeder without a dedicated breaker
From: William Miller <[email protected]>

Friends:
A prospective client has a 200 amp meter / main / combo. There are only a few breakers in it feeding the well, the pool house / barn and the garage. There is no breaker feeding the sub panel in the laundry room that has all of the branch circuit breakers for the house. Instead there is a plug-on connection block feeding a large gauge aluminum romex feeder into that sub-panel. The plug-on connection block has hex set screws large enough to handle the feeder conductors.
Having no circuit breaker, this feeder is over-current protected by the 200 amp main breaker. Is this legal?
To rephrase the question: Does a feeder require a dedicated circuit breaker?
Thanks in advance,
