I have a question regarding this topic without hijacking the thread... I understand that plugging in a shorepower cord with power causes arcing, leading to premature failure of the cord and/or the plug. I have always shut down power on the boat via the the two main breakers on the panel inside before disconnecting/connecting. Our breakers are off the dock, up the hill at the meter, and therefore we never click those off. Our power cords are permanently run from the dockside receptacle to the side of the boat where our hookups are so that we only make the connection between the female end of the cord into the shorepower inlet and then tighten done the retention collars (we have spare cords stored on the boat for when we are away at other docks); but my thought process has always been that if there is nothing pulling a load on the boat side, that no arcing would occur even if the cord is energized from the dock. Is this a wrong assumption? One that could be putting our cords at risk for fire and premature failure? This is two 30/120 shorepower connections that I'm talking about. The current set up allows us to dock and undock without ever getting off the boat... water, cable and electric, along with the dock lines are all handled from onboard the boat, meaning it would be a serious PITA to have to disembark the boat, run up the hill to the meters to have access to the breakers (especially at night, as the meters are in an unlit area on the side of a steep grassy bank).
