FYI Measuring campground voltage

[Joe Hogan]

Many campgrounds discourage people from probing their power pedestals with a voltmeter. A quick solution to determine line voltage is a internally wired voltage gauge like the one installed on my RV. Displays voltage for line 1 & 2 and amperage draw.

RV Power Monitor. At a glance I can see the voltage being delivered by the Pedestal.

Hughes Power Watchdog does this too, and I can access it from my phone!

In the used coach we bought, the prior owner installed the display/monitor at the panel above the driver so we can see the voltage and amp draw on each leg. But we also use a pedestal surge protector too from Hughes, so now I can be even lazier and while sitting in a chair I can just look at my phone like the phone screen shot MapNerd shared above. ?
