Do you have an inverter that’s also on that 120v breaker? The wire colors are a bit off too. AC should be black or red for load, white for neutral and green for ground and be stranded wire. No solid wire on a boat. DC in newer boat have different colors and the ground color has a new standard being yellow for ground, black in older boats. Red is still positive, green is still negative. Still all stranded wire.
On the surface it sounds like you have the incorrect wires going to that breaker and plug.
I trace 120v with a Klein sensor. I just have to get the tip near an energized circuit for it to read. For 12v and circuits that are not energized I use a Fluke sound wire tracing tool. It works by running a light current through the wires and following the sound. It’s more sensitive than the 120v but do not use the 12 on energized 120. Yes, both sensors work through walls.
