Component/end-product compatibility is the critical link between certification of a component and certification of the end-product in which the component is used. Use of UL Recognized Components in a spa (or any other product) does not mean the spa itself is UL Listed.

If you're unsure of the exact meaning of a given UL certification (Listing or Recognition), look in the appropriate UL Product Directory for information about a specific product certification and marking information. For example, the Swimming Pool and Spa Equipment category (WABX) begins on page 505 of the 1997 Electrical Construction Equipment Directory. The Directory will also explain any limitations and the extent of UL's evaluation in the information section preceding each product category.

If you've exhausted your information sources, here are some ways we can help. If you have the product name and catalog number, part number or system designation, call UL's Data Services at +1-847-272-8800, ext. 42396. ULDS will help find the UL category for the product in question. If you need to verify a Listing or find a file number for a product bearing a UL Mark, call +1-847-272-4909, or Customer Service at +1-877-ULHELPS. As always, Codes & Technical Services staff members at each UL office will help with other questions you may have concerning UL certifications, code compatibility or product installation.
