Looking to determine the ac wire size from the inlet receptical to the service panel on a 1987 C36. The ground lug arced and got hot frying the shore power cord, inlet receptical at the boat, and melting and burning the ac wire for a distance from the receptical. Have replaced the power cord and inlet receptical at the boat and will run new wire from the inlet receptical to the power panel. The 30 amp Marinco shore power cord is 10 gauge but I believe the marine grade wire from the receptical to the power panel is 12 gauge. It looks the same size at the power panel as all other wire running to the power plugs which I am sure is 12 gauge, but there are no markings that I understand to indicate the wire size. My ac wiring diagram for the boat outlines the layout but does not identify wire size like the dc wiring diagram does. Anyone know the wire size for the panel feed from the inlet receptical to the power panel on the C36, or can confirm that it is in fact 12 gauge?
