Re: [RE-wrenches] mounting hardware and U.L.
http://solarabcs.org/about/publications/reports/module-grounding/index.html (see the Issues Recommendations report) Phil is right that UL 2703 isn't finalized yet so it's not actually a requirement. However, I imagine that module installation manuals and UL 1703 will both refer to 2703 soon, so it's not something that you'll be able to ignore forever either. Since 2703 still isn't approved (see: http://www.ul.com/global/eng/pages/solutions/standards/accessstandards/catalogofstandards/standard/?id=2703_1 ), I don't see how Unirac can claim that they have an ETL mark for 2703. Ray is right that an AHJ can't reasonably require equipment that doesn't exist. Just as NEC 2011 690.11 doesn't require you to use string inverters with arc fault protection, since no such unit is available (well, at least until SMA just started offering this for their standard low-freq Sunny Boys)-- no inspector should require anything listed to UL 2703 yet. A relevant section is 90.4 (this section is copied from 2008). ** The authority having jurisdiction for enforcement of the Code has the responsibility for making interpretations of the rules, for deciding on the approval of equipment and materials, and for granting the special permission contemplated in a number of the rules. By special permission, the authority having jurisdiction may waive specific requirements in this Code or permit alternative methods where it is assured that equivalent objectives can be achieved by establishing and maintaining effective safety. This Code may require new products, constructions, or materials that may not yet be available at the time the Code is adopted. In such event, the authority having jurisdiction may permit the use of the products, constructions, or materials that comply with the most recent previous edition of this Code adopted by the jurisdiction. ** On 2012/7/20 0:52, Marco Mangelsdorf wrote: Thanks, Phil.

[RE-wrenches] mounting hardware and U.L.
Does anyone know whether there are U.L. standards when it comes to PV mounting hardware?

Re: [RE-wrenches] mounting hardware and U.L.
See UL 467 for grounding clips. See http://www.bizjournals.com/prnewswire/press_releases/2012/07/09/NY36598 for other standards. I've never been asked about listings for mounting systems except the UL 467 listing for bonding the rails using listed devices.

Re: [RE-wrenches] mounting hardware and U.L.
I don't think any bolts, washers, nuts, screws, lags, all thread, etc are UL listed either. There aren't UL batteries, so they can't prevent us from powering off grid homes. Is concrete UL listed, when we do a ground mount array or a Uffer ground? The card being played here is article 110.2 'equipment shall be acceptable only if approved'; then article 100 defines approved as being 'acceptable to the AHJ' I call this little bit of NEC BS, the AHJ = God conundrum. 110.3 (A) provides many other criteria besides listing to verify the acceptability of equipment, so regardless of the seemingly omnipotent 110.2, an AHJ can't reasonably require equipment that doesn't exist.
