Frank,
I believe that your installation is an Article 520 application, and not 525. Look at the scope of 520 and the defintiton of "preformance area" in the 2002 code. As I recall, the scope of Article 520 was changed and the defintion added to make it clear that "road shows" are coverd by 520 and not 525.
