[RE-wrenches] Ilsco SGB bonding lug

Grounding rods that are UL467 listed don't necessarily list outdoor rated as a specification. That is implied I believe. You probably wouldn't need these lugs for those indoor PV modules. :) I like the looks of that lug. However, I've been using WEEBs too long to go back now. Jason Szumlanski Fa

Some of the aluminum lugs are indoor-rated. They have a set screw will rust in an outdoor environment. That's one of the classic John Wiles slides. I'd just watch out for that On Aug 27, 2012, at 3:04 PM, Jay Peltz wrote: > Hi Brian > > Isn't another way to go: > Use the AL lugs and AL gro

Yeah, but this one is marketed as a solar bonding lug. I think it's safe to say that it appropriately rated for outdoor use. It's always good to double-check, of course. Jason Szumlanski Fafco Solar On Mon, Aug 27, 2012 at 4:11 PM, David Brearley < david.brear...@solarprofessional.com> wrote:

William, The transformer creates a Separately Derived System. You need to bond the the neutral, and the equipment ground there or at the first Disconnecting Means, which would be the combiner panel. The chosen bonding point must also be connected to a grounding electrode. Per2011 NEC 250.30. Dic
