DC-GFP Installation
I'm finally wiring up my breaker box and have a question regarding the GFP.  One end of the .5A breaker goes to ground bus - does the other go directly to the negative battery terminal?

Thanks for the help;
Steve

I tried for nearly an hour to find a diagram that shows exactly how to wire a GFP breaker into a PV source circuit of a PV array mounted onto a dwelling and I could not find not one diagram or schematic or even an installation manual.
To think that these things were required by the NEC on PV source circuits at a time when nobody even made such a thing.
The closest thing I could find is at HomePower.com if you go there, just type it into search and its the second article, I think.

To be sure, whoever made your GFP breaker, sent a diagram?

yep, lizandro is correct.  if you tell me what dc load center or what gfp you have (outback, midnite, or xantrex) i can get you to the appropriate diagram.
