I have been reading the articles related to the P42 fire and electrical cords and thought I would pass on what I have discovered. Within six months, the female end of my Panel B power cord and the male receptical on the boat were partially melted. When replacing the male receptical, I noticed that the wires in the screw-down terminals were not tight. I then inspected the Panel A male receptical and found the same thing. After discussing this with electrical engineers (one of which investigates fire causes for insurance companies), I now understand what is happening. The terminals on the back of the male recepticals are screw down type. The wire used is stranded copper. Marinco, the manufacturer of the receptical recommends no tinning of the wire ends. As the screw terminal is tightened, the strands are deformed from round to the shape of the terminal. Over time with the vibration of the boat, the strands tend to deform even more resulting in a loose connection. This creates heat which then begins to melt the female shore power cable that is plugged into the boat. I now open the male recepticals once a year and check and retighten the terminal screws, and I have found them to be slightly loose. Another thing that I have found is that when the female cord end is being attached to the boat, hold locking pressure on the cord end by twisting while tightening the locking ring. If the female cord end is not locked all the way clockwise, arcing will occur that will cause heat and trip breakers.
