Does it really matter if the breaker on shore is off... if the breaker at the boat is off and there is no flow of power?
I do think this is a combination of things.
Poor connection due to not twisting the connector on all the way.
Wiggling the cable and causing arcing.
Plugging and unplugging while power is flowing.
Salt & other stuff causing corrosion and poor connection.
This came up on another list and Hubbell was mentioned as using a different method of connecting the lugs to the wires. Sorry I don't recall the differences.
Rings can be forced on to the plugs, I've done it. I don't recall ever seeing a dockside recepticle with threads for screwing the ring to.
