[RE-wrenches] Ilsco SGB bonding lug

[benn kilburn]

Thanks for the feedback Wrenches, lots of interesting comments,

However I'm still wonderingŠ..
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.  See hereŠGBL LAY-IN AL/CU
<http://ilsco.com//ProductsDetail.aspx?kfjkff=cjiDRFP14PUgtVid3pn1cQ%3d%3d&f
jjfhjhj=nY1wgyVO%2fE%2bFsQNfsmn%2f4OZ3BP5vHo5NcMahtvvHLIc%3d> .

As well, and as Gary pointed out with his second link, for a module
bonding/grounding method to be acceptable, it must be recognized by the
module manufacturer, no?
Which means that any new bonding product on the market must have the
blessing  of each mod mfgr.
(by way of letter or mention in its install manual).  I have come across
inspectors that actually look for this.

Jason, 
you wrote "I like the looks of that lug. However, I've been using WEEBs too
long to go back now." I agree, and i'm not looking to replace weebs with
these, but these certainly seem to have a place in the What do you use for
the bonding connection from the ?rails?
This SGB lug was suggested for this purpose as well.

Here's the Ilsco listing from UL, where it's classed as "Grounding and
Bonding Equipment":

 The GuideInfo for Grounding & Bonding Equipment lists:
