RV Electricity – Just Ask Mike (J.A.M.): What is an RVelectricity™ Master Class?

Welcome to my J.A.M. (Just Ask Mike) Session, a weekly column where I answer your basic electrical questions. If you’re a newbie who’s never plugged in a shore power cord (or ask – what’s a shore power cord?), or wonder why your daughter’s hair dryer keeps tripping the circuit breaker, this column is for you. Send your questions to Mike Sokol at mike (at) noshockzone.org with the subject line – JAM.


RV Electricity – Just Ask Mike (J.A.M.): What is an RVelectricity™ Master Class?Dear Mike,

I keep hearing about your RV Electricity Master Classes, but I can’t find any real information on what’s included. And can it really take three 90-minute sessions? Is there that much to learn about RV electricity? —Stan the Man 

Dear Stan,

Yes, that’s the plan, Stan. There really is a lot to learn about RV electricity, since there’s a bunch of different electrical systems in a typical RV. To prove it, here’s the syllabus of what I’ll be teaching at the RVillage 2020 Rally. (Read more about the Rally HERE.)

Now do you believe me?

RV Electricity – Just Ask Mike (J.A.M.): What is an RVelectricity™ Master Class?If you look at the picture of my desktop, you’ll see the demonstration pedestal I designed and built which allows me to fully test a 50-amp 120/240-volt RV pedestal using only a 120-volt wall outlet power. Plus I can use the Variac to show how EMS surge protectors respond to anything from 0 to 280 volts, demonstrate open and hot grounds, create a 240-volt 30-amp RV outlet, and lots more crazy and dangerous situations you might encounter in a campground.

I’m adding more to my RVelectricity itinerary all the time including what 3-phase 120/208-volt power in a campground looks like on an oscilloscope (it’s now allowed in campgrounds per the NEC 2017), and how to diagnose GFCI leakage tripping.

RV Electricity – Just Ask Mike (J.A.M.): What is an RVelectricity™ Master Class?OK, everyone. Remember that electricity is a useful and powerful force, so we all need to pay attention to safety precautions while using it.

Let’s play safe out there….
