[VAC] Re: Water & electric

[Dr. Gerald N. Johnson, electrical engineer]

I'd put in GFCI for all circuits. A GFCI in the trailer feed or in the
trailer panel or load circuits (a GFCI receptacle with subfeed wires is
about $7 while a GFCI breaker is about $40) can work even if the feed is
badly wired. And there's no 30 amp pedestal receptacles with GFCI, only
20s in modern pedestals. And that's only MODERN pedestals. There's often
no code inspector in rural areas where campgrounds mostly are so there's
no inherent reason to trust pedestal wiring.

I'd like to see either aluminum or stainless steel ground connection
bolts with star lock washers and AlNox (or equivalent). Galvanize is
better than cadmium plated is better than bare steel against aluminum
but not a whole lot.

Reaching up to the assist handle while standing in the morning dew and
finding the shell alive with 120 volts is not a good way to start a day.
I can end it early. It can end everything early. Ventricular
fibrillation appears to be a slow death, guaranteed unless there's a
defibrillator applied in under 4 minutes. Extra checks and care can be a
lifesaver.
