A Hockey Puck 15/30Amp Adapter to Avoid
This is a style of hockey puck adaptor that was responsible for an intermittent hot skin (open ground). Notice how it shows "Made in USA", has "CSA" symbol, and no mention of "UL". CSA stands for "...

I have a dog that I got in the USA, that has Canadian "Papers"....now I have to wonder if he's gonna short out too!:B
Glad that nobody was hurt with this, and thanks for passing this along, I'm sure that lots of folks have them.
Do you think that it is faulty, from day one, or did it maybe get overheated, and then fail? Even a well made unit can't take a lot more amps than it's designed for, though I'm sure there is a bit of room for error/overload.
The problem was from day one. The round female 30A ground connector was too large to mate with the corresponding 30A male connector. It was an intermittent open circuit that did not conduct any significant current. The normal current through a ground conductor is less then 5 millAmps (0.005 Amps). Once the bad connection was established I crimped the female through the rubber as a temporary measure until I could get a proper 15A to 30A Dog Bone adaptor. You can actually see the conductor surface I deformed/crimped in the picture.
