Hopefully any crew installing PV, and familiar with this debate (which they should be) can easily distinguish between the GBL-4 and the GBL-4DBT. The weight difference is quite noticeable. If it feels light for its size, it's aluminum, dont use it!!! If it has some distinct weight to it, then it's most likely the copper DBT, giv'er! So what other non-conductive materials are out there that could help resolve this frame bonding issue? Sunteck's BIPV SolarBlend module uses a polycarbonate frame which requires no bonding. Do any of you have any experiences with these? How were they to handle, install? Do they offer any hope or support for non-metallic module frames? benn DayStar Renewable Energy Inc. b...@daystarsolar.ca780-906-7807 HAVE A SUNNY DAYFrom: r...@solarray.com Date: Mon, 13 Sep 2010 11:14:36 -0600 To: re-wrenches@lists.re-wrenches.org Subject: Re: [RE-wrenches] The Demise of WEEB
I didn't do the original install, and I couldn't ID the lug because of the corrosion.I believe everyone is correct that this isn't the DBT rated lug, though.Another reason to use the WEEB: a crew can't accidentally install the wrong (but almost identical, when new) lug. I'm sure the non-DBT lugs got mixed together in a bin at some point.

Here is an explanation of the differences between both ILSCO GBL 4 lugs from John Wiles Code Corner in Homepower issue 102 "The Ilsco GBL-4DBT is a lay-in lug made of solid copper, which is then tin-plated. It has a stainless steel screw to hold the wire. The lug accepts a #14 (2 mm2) to #4 (21 mm2) copper conductor. It is listed for direct burial (DB) and outdoor use and can be attached to aluminum structures (the tin plate). The much cheaper Ilsco GBL-4 lug looks identical, but is tin-plated aluminum, has a plated screw, and is not listed for outdoor use."
