Burndy's changed its part# from the CL50-DB-T to the CL50-1TN. Still
direct-burial, still tin-plated, still "commonly used for solar panel
grounding." The tech support guy I spoke with last December said that
their lugs are now all direct-burial, so they decided that there wasn't
a point in keeping up the DB designation.

Todd -
Burndy and Ilsco both make similar tin coated copper lay in lugs.
Here are two manufacturer part numbers:
Ilsco GBL4 DBT
Burndy CL50-DB-T
Other wrenches, let me know if these parts numbers don't sound right.
As has been mentioned on this list several times, Wiley makes really
nice lugs for grounding your rails:

Both the Burnday and Illsco lugs are similar as far as I can tell and
include a stainless set screw. Prices vary, so be careful. You then
need to decide how to you want to fasten them to the module frame.
Many folks use SS 10-32 thread forming screws but I found that the
crew members were commonly stripping the soft aluminum module frames
during installation. I can't keep those guys away from their impact
drivers! Now we use a SS 10-32 thread forming screw and a SS kep nut
on the backside of the frame. The thread forming screw cuts right
though the manufacturer supplied ground spot and them the kep nut
assures that we can go good and tight. We always use a SS star washer
between the lug and the frame. And the kep nut includes a star washer
built in which keeps the install fast. Sample nut pic:

These lugs are widely available from most solar suppliers.
Yea, those old standard aluminum lay in lugs just don't hold up in
our climate, at least.

Does anyone have a part number for the lay in lugs they use for
module grounding? I don't want copper or aluminum ones because of
problems with dissimilar metals. Don't they make a tin plated copper
one that works with the aluminum module frames? My wholesaler cannot
seem to find the part number.
Thanks,
Todd _______________________________________________ List sponsored
