Power Consumption Furnace Question
I have a 27 ft Travel Trailer. It has a Progressive Industries 30 Amp EMS system installed (hard wired). This past weekend we were camping at a campground that had pedestal 30 Amp power. We noticed...

well the PI current display is NOT very accurate, I called them to talk about what I saw was verifiable errors when checked with a NIST calibrated current meter. They agreed, it's not very accurate or repeatable. A qualitative readout at best.
But, the furnace should draw around 6-12A from the 12V source, that's an additional 1A or so from 120V.
the lights dimming some isn't unusual. A fraction of a volt drop can cause a noticeable drop in incandesent light brigtness. brightness is related to the 6th power of applied voltage!
