Overview of Changes: New Annex C (United States only - Protector Grounding Conductor – For Use in Communications Circuits) and D (Exothermic Welding Connection Systems).

Special Note => In addition, this SUN also announces publication of 1st Edition UL 2703 (Mounting Systems, Mounting Devices, Clamping/Retention Devices, and Ground Lugs for Use with Flat-Plate Photovoltaic Modules and Panels). All UL 467 certified/listed products intended to be used in such PV modules and panels will need to be re-evaluated to the requirements of UL 2703. Any UL 467 certified/listed products identified for use in such PV modules and panels are advised that installers, contractors and local Authorities Having Jurisdiction (AHJs) may reject a UL 467 certified/listed device if used in the PV industry.

Specific details of new/revised requirements are found in table below

Client Action Required:

Current Listings Not Active? – Please immediately identify any current Listing Reports or products that are no longer active and should be removed from our records. We will do this at no charge as long as Intertek is notified in writing prior to the review of your reports.
