autoformers for dummies (me)
Hi all, I've heard folks saying autoformers "steal" power from the campground and hence from other campers. Here is my understanding of what happens. The total wattage remains the same less abou...

Hi Kayeg1,
I already addressed this in a previous post. Campground National Electric Code requires them to provide 41% of the energy that the entire loop is rated for. That works out to 1476 watts--so at 1248 I'm taking less than my fair share.
In other words, if there is 90 volts, I'm part of the solution, not part of the problem.
BTW the lowest I've ever seen was at a rural Church at 100 volts from a 15 amp circuit at the end of a 100 foot #12 cord. That has happened exactly once. I doubt that I'll see 90.

What I see missing from this calculation is fact that if undersized wiring drop the voltage to 100V under 10 amps draw, it is going to drop even more when you start pulling 12amp.
Meaning you neighbor suddenly is having 90V
If the wire has certain capacity, putting "vacuum" on it means somebody else has to get less.
