Hello, Trying to add shore power outlet to my system. Not sure exactly what I need to do to add the outlet in the picture to the system (also pictured). With the installer I talked about wanting to add this later but now I can't remeber. I though he said to add it with the "IN" labled cables with the breaker but that doesn't seem right to me now. There is one connection to the "OUT" line (farthest right breaker) and nothing to the IN line (next to the OUT line).
