I was reading another message thread on "popping breakers" and it occurred to me that though whole discourse that nobody mentioned checking "shore" power outlet before "plugging in" either at home or away.
Seems to me that people would WANT to know if shore power was safe before connecting...
This simple tool would verify shore power before you plugged in and would go a long ways to insure your connection and appliances inside may be safe.
And they are NOT really expensive....
