Thirty-amp connectors are a perennial problem in marinas. I've seen many failures and meltdowns over the past couple of decades. Many of these could be traced to "user failure", i.e., overtaxing the connectors by overloading them, not cleaning them, not keeping them dry, etc., etc.
The sad truth, however, is that we're now seeing FAR TOO MANY failures of 30A Marinco connectors to believe that its always "user failure".
First, the design stinks: these things cannot handle anywhere near 30A continuous power, without heating and burning.
Yes, do everything possible to keep contacts clean and dry, and try to limit power draw to not more than 25A or so. That will help.
But, bottom line, IMHO these connectors are real crap. Be very wary of them....i.e., ALL 30A connectors....but, especially, those recently coming out of Marinco. These seem to be substandard in construction.
Is this really the best we can do?
