Tom,

Boy was I way off. I came up with 110.58 by doing a search in my NEC 02 software I bought fron the store on this site. I have to make sure to scroll back a little further to see what it is being applied to. I thought the local disconnect rule was a general rule that applied to all equipment 300VA and larger that was not cord and plug connected.

As to protection of the secondary conductors, isn't that accomplished by the primary protection, both fault and overload? That's, I guess, what I don't get. In Table 450.3(B), under what scenario would the column describing no protection needed be?

George, you may have just answered that question. I don't have my book or CD with me, but I'll be referencing your section for clarification. Thanks.
