bulk charge to get by till the sun comes back would work well. If it has a taper charge from the factory t would take almost forever to charge a large battery bank. I do like the output, but probably will hate the price. Later, Bob Ellison -Original Message- From: re-wrenches-boun

This is true. They must be internally ganged when tripping. Be aware that these breakers may not be internally ganged when you manually switch them on and off though. That is where the pin comes in. boB On 2/27/2013 11:05 AM, John Berdner wrote: Larry: The Code requires parallel

I don't know if they are thicker or stronger than the others, but I'm sure they are as good or better. I believe our purlins were 0.62 thick. Certainly some kind of gooey is needed for a seal between the foot and the roof. Lots of different flavors or those, most of them good. Good Luck, Bob-O
