[RE-wrenches] question about pole mount interconnection

[Benn At DayStarSolar]

I would like to retract the part of my last post on this thread where I was referring to the bare conductor size. My bad, I wasn't thinking clearly when writing that last email. Lots of numbers in my head today. A #8 bare with #10 conductors is way out to lunch :/
The bare conductors are indeed always included and are available in different sizes, to an extent.
