Question: Canadian UL White Book
I have read many times in the UL Question Corner column references to the UL White Book. I am a Canadian electrical inspector and want to know what is the UL White Book and is there a UL White Book for Canada?
The UL White Book is a regulatory reference tool that UL provides to AHJs and others to verify the Listing scope of UL Listed electrical products installed in the field. The Guide Information for each UL product category details the scope of the Listing, important installation and marking information, identification of the standard or other requirements used for Listing as well as how to identify products Listed under the product category. The intent of the White Book is to enable an AHJ to look at the UL Mark on the product and cross-reference the product identity from the UL Mark to the index in the White Book and locate the Guide Information and scope of Listing for the specific product category.
The White Book has been printed annually for over 30 years. For many, it is considered part 2 of the Code, because without the information in the White Book it is difficult to determine compliance with the Code.
Until now, UL has not printed a Canadian White Book. Starting in 2007, UL in coordination with ULC (Underwriter’s Laboratories of Canada) will print the Canadian White Book. The Canadian White Book will contain the Guide Information and scopes of all Canadian certified product categories from UL and ULC that are applicable to any discipline inspector, not only electrical product categories as is done for the UL White Book.
Besides incorporating the product categories for Canadian certified products of ULC and UL, the Canadian White Book will also contain a detailed explanation of how to use the book titled, “Practical Application of the Canadian White Book in the Field.” In addition, Appendix A and B, will contain a Quick Guide to using ULC’s and UL’s Online Certification Directory so that you can easily search the online databases for verifying certifications.
The Canadian White Book will be available the first week in July.
