Kirpal. The Ilsco lug GBL-4 also comes with a stainless steel set-screw as stated here.GBL LAY-IN AL/CU <http://ilsco.com/ProductsDetail.aspx?kfjkff=cjiDRFP14PUgtVid3pn1cQ%3d%3d&fj jfhjhj=nY1wgyVO%2fE%2bFsQNfsmn%2f4OZ3BP5vHo5NcMahtvvHLIc%3d> if that is all it takes to use the AL lug outdoors (stainless steel set-screw), then why have we been steered towards the 'direct burial rated' tin-plated copper lug instead of an AL lug with SS set-screw?
I'm not trying to make a case to not use the SGB lug, I like it and would like to keep some in stock, as they seem pretty useful, I just want to have my bases covered if/when an inspector questions me on them being approved for the application. Dan, Agreed! Been trying to get an answer from Ilsco, just tracking down the right person with the answers.

Stainless hardware and tin plating is equivalent to the WEEB lugs....Tin plating and stainless hardware is as good as anything else available as far as outdoor ratings are concerned..... I see your point that it is not explicitly stated for outdoor use....however being marketed for use with solar panels also seems to imply rather obviously that it is outdoor rated.....in my unofficial opinion. -- Sunny Regards, Kirpal Khalsa NABCEP Certified Solar PV Installer On Mon, Aug 27, 2012 at 4:11 PM, benn kilburn <b...@daystarsolar.ca> wrote: > Thanks for the feedback Wrenches, lots of interesting comments, > > However I'm still wondering.. > How does one confirm that it is specifically approved for outdoor use? > Other than assuming it is implied (because it is 'marketed' as a solar lug). > As far as I can tell UL 467 does not imply "outdoor rated" as the aluminum lug > "GBL-4" is also UL467 listed.
