Remote distribution panel feeders

Is there a minimum size feeder for remote distribution panels. I read it was 60 amps but I just wanted to make sure.

The feeder just needs to be sized for the load served. The NEC does not mandate a size.

Ok thanks. IDK why I thought the minimum was 60 amp. Is the minimum to a detached structure 60 amp?

No there is no minimum for a pony panel. Its maximum load needs to be 80% of its service size.

No, same rules, just sized to the loads.

225.39 Rating of Disconnect.
The feeder or branch-circuit disconnecting means shall have a rating of not less than the calculated load to be supplied, determined in accordance with Parts I and II of Article 220 for branch circuits, Part III or IV of Article 220 for feeders, or Part V of Article 220 for farm loads. Where the branch circuit or feeder disconnecting means consists of more than one switch or circuit breaker, as permitted by 225.33, combining the ratings of all the switches or circuit breakers for determining the rating of the disconnecting means shall be permitted. In no case shall the rating be lower than specified in 225.39(A), (B)](http://code.necplus.org/document.php?field=jd&value=necss:70-2011:id02011002624#70-2011:id02011002624), ©](http://code.necplus.org/document.php?field=jd&value=necss:70-2011:id02011002626#70-2011:id02011002626), or (D)](http://code.necplus.org/document.php?field=jd&value=necss:70-2011:id02011002628#70-2011:id02011002628).

(A) One-Circuit Installation. For installations to supply only limited loads of a single branch circuit, the branch circuit disconnecting means shall have a rating of not less than 15 amperes.

(B) Two-Circuit Installations. For installations consisting of not more than two 2-wire branch circuits, the feeder or branch-circuit disconnecting means shall have a rating of not less than 30 amperes.

© One-Family Dwelling. For a one-family dwelling, the feeder disconnecting means shall have a rating of not less than 100 amperes, 3-wire.

(D) All Others. For all other installations, the feeder or branch-circuit disconnecting means shall have a rating of not less than 60 amperes.

The way that has been interpreted by one AHJ is that rule only applies to the disconnect rating, not the actual feeders.
