Dock to boat shore power connector fried...theories as to why ?
Happened sometime during the week, one leg of 220 destroyed/melted at the boat connector (i.e. 110 house current works but 220 A/C units don't). Connection at boat was good...twisted and locked. No hints of trouble otherwise, looks perfect at dock pedestal end, no breakers tripped anywhere, A/C (and all else) units work fine via generator.
