Question about attaching the Busbar

Post by rajah9 » Tue Oct 28, 2008 8:21 am

I'm interpreting the picture on p. 3 of the instructions to mean that the positive busbar attaches to the chassis using the 1/0 lug, and contact with the chassis is ensured with the star washer. But isn't the ground terminal also attached to the chassis?

I'm wondering if there's some insulation to isolate the positive busbar from the chassis, because it looks like + and Gnd will be tied together, otherwise.

I talked to Scott at Solar Electric Supply, and he answered my question. I am missing the fuse holders, which are going to slide into the rail; they will hold out the busbar so that it will not contact the chassis.
