[RE-wrenches] Ilsco SGB bonding lug

Kirpal.

The Ilsco lug GBL-4 also comes with a stainless steel set-screwŠ as stated
hereŠ.GBL LAY-IN AL/CU

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.

Cheers,

Benn...it looks like that lug has "stainless hardware for corrosion
resistance"  as stated on the brochure....That would be the biggest
consideration as David Brearly mentioned earlier in regards to rust
potential.  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.
