[RE-wrenches] Ilsco SGB bonding lug

[Kirpal Khalsa]

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.
