Something missing in 2011?

[jumper]

Both my NEC and NECHB say this:

450.3 (B) Transformers 600 Volts, Nominal, or Less. Overcurrent
protection shall be provided in accordance with
Table 450.3(B).
Exception: Where the transformer is installed as a motor
control circuit transformer in accordance with 430.72(C)(1)
through (C)(6).

I cannot find a 430.72(C)(6).:?

Senior moment or is it not there?

It is showing that it was added but it is not there. In the 2008 there was no C(6) and 450.3(B) only stated thru C(5)

NEC Plus (online NEC) says "430.72(C)(5).

I bet they made a mistake and caught it, NEC plus would be easy to correct, a book is not.

I think somewhere they have a listing of revisions, corrections, etc. and what the revision was. I think your printed books also have some kind of revision number to tell you what revisions you have in your copy.

This was pointed out to me a few years ago, but I don't remember all the details. I was purchasing code books at that time through an organization that would take early orders before the books were even published. We were told those early books would have editorial errors in them and if you had an older version and a newer revision you will find mistakes that were corrected in the newer revision.

Look around in the front matter of your book and you may find what I am talking about.

ETA: I found this at NFPA site and it even includes the section you question on the list.
