Shore power not getting to boat. Ideas? Maybe an easy fix?

Invaluable trouble shooting tool. Corrected shore power outlets in two different harbors in Newfoundland which had reversed polarity,

Not being picky but what type of or how do you use a non contact tester to indicate reverse polarity?

+1.

Here is a little known fact. The hubble style 30a connector was originally designated as a 20a connector. When pressed into marine service, they stated 30a intermittent. Somewhere along the way, "Intermittant" was dropped.

If I were King, Smartplug would be required. It is that good. The hubble style is a gamble. Do you like to gamble with your boat???

Great question IP485! It turns out the hot black wire is always connected to the narrower of the 2 flat prongs in all conventional 125VAC plugs, but the wider of the two non-flanged curved prongs of Hubbel style 30A 125VAC plugs! (What could go wrong?).

To be honest, the Xantrex charger showed the Polarity Fault red LED the first time it happened. I then started carrying my pocket tester, and before hooking in put the flat tip into the wider outlet on the dock to confirm correct polarity.
