We had an electrical failure this week that I thought I should share.    The 30 amp shore power inlet plug developed a short that melted both the plug and shore power cord socket.  

The wiring was inspected late December when I did a function test on the galvanic isolator.   Over the last week we had strong winds with our boats moving around at the dock.  At one point I checked and winds were over 50 mph and they were most likely much higher.  

The failure was either (or a combination of) cracked insulation under the strain relief bar or heat build up over the contacts.  Both the plug and socket were destroyed before the breaker at the nav station tripped.   

I replaced the plug and socket with a Smart Plug which was a job I’d planned for the spring.
