Hi SoundGuy,
Let's pretend I'm going to plug in my RV at a 30 amp site.
First step I take a dogbone adapter that is 30 to 15 and plug it in.
Next step I plug a kill-a-watt meter into the dog bone 15 amp outlet. I note the voltage.
Next step I plug a polarity checker into the kill-a-watt.
Next step I unplug the polarity checker and plug in a 1500 watt heater.
Next step I turn on the heater full blast and check for voltage drop (I.E. Voltage drop under load). I note the voltage.
Finally, if everything looks good, I'll plug in my RV.
If there is too much voltage drop then I'll adjust the Magnum inverter/charger to try to compensate. I've got a pretty good idea what to set the amperage limit at to force the Magnum to do, not just load support, but voltage support. Once I have the autoformer I'm hoping that I won't have to use the Magnum to do that. I will, however, have to limit the input amperage based on the supply voltage so as not to cause amperage overload at the pedestal.
If it is a 15 or 20 amp outlet I do the same but don't need the dogbone adapter.
If it is a fifty amp outlet, I use my "break out box" and check both legs before I plug in. It does mean doing it all twice--but that's what keeps me in my comfort zone.

Hi rockhillmanor,
If you quote the whole statement it makes it clear that I always check the pedestal under load before I plug in.
Huh? :h That makes no sense ... in order to check a source supply under load you must first be plugged into that source so any load you're imposing yourself is reflected in any voltage drop created. :W
