I'll check it out. I will be running 500 watts of solar and using #6 wire. It looks like this connector is more for light duty applications.
It doesn't look like an NMO is what I need. The unit that camper 101 mentioned is the right type but I don't think it will handle the power that I will be running. I will know more tomorrow when I can talk to the vendor.What type of mount are you looking at? NMO or what.
