Question: UL product categories
In the September-October 2006 edition of the “UL Question Corner” you detailed many changes to the 2006 UL White Book. The Index of UL Product Categories Correlated to theNEC-2005 seems like a great tool, how do I use the index to determine compliance with the NEC?
Answer
The new Index of Product Categories Correlated to theNEC-2005 provides a direct link between individual sections within the NEC and corresponding UL product categories that may be applicable to that section of the code. The index starts on page 311, and is simple to use, just look up a particular NEC section number and read across to locate the corresponding UL category code and page number on which the complete guide information for the category is located. This will direct you to the UL Guide Information for the product category, which provides important information regarding the applications for which the products covered under the product category are Listed. Among other things this includes a description of products covered, selected installation marking information, the standard used to investigate the product, and a description of Listing Marks provided on products covered under that category. This information goes a long way in helping to determine the suitability of the installation for compliance with the Code as well as compliance with NEC 110.3(B).
It is important to remember that the Index of UL Product Categories Correlated to theNEC-2005 is intended to serve as a tool for identifying product categories that correspond to particular code sections, and their location in the White Book. Locating the Product Category Code on the pages indicated will provide the user with the UL Guide Information for the applicable category code. This Correlation Index may not include all UL product categories that may be applicable to a particular code section. The user should independently confirm the applicability of the product category to the code Section and verify that no other UL Product Categories apply to the installation. The installation of products for the categories identified in the Index are subject to approval by the authority having jurisdiction (AHJ).
