Taking the Mystery Out of Your 3 RV Electrical Systems

Voltage, amperage and wattage what do these terms have to do with RVs? This class will help you answer questions and more like:

  • Why do my interior lights dim then get bright again?
  • Now what do I do? I heard a pop then everything electrical went dead.
  • Shore power, inverters and generators – what do they all have in common?
  • Why is it my popcorn taking longer to pop in my RV microwave?
  • How does my Residential refrigerator operate when I travel?
  • And so much more……

You will learn how the 3 Electrical Systems operate in your RV. We will cover how you can quickly calculate your power needs to help you what you need to do to keep things working in your RV. When it is ok to use power reducers and adapters and how do use them in a safe manner. What are these things we call the EMS (Energy Management System), circuit breakers and fuses and how they are used to protect your RV?

 Learn to Use Your Volt Ohm Meter

The Professor will be giving you your very own volt ohm meter. This one little device will give you a peek into the inner workings of your RV’s electrical systems by showing you how to test for blown fuses and checking the various voltages that you have.


Hands On Labs and Tour of Your 3 Electrical Systems

Hands-on learning is the most effective way to best understand how your RV works. It will help you side-step issues before they become an problem. You will be checking your 120 Volt AC electrical panel box in your RV to see exactly how it works. You will test each wall receptacle for correct polarity as well as identifying which ones are GFCI protected that work to keep you safe.

Did you know that your RV has a battery that acts like a piggy bank to give you 12 volts DC power that you can draw from when you are not hooked up to Shore Power? The Professor will show you how issues with your 12volt DC Battery system will affect your furnace, refrigerator, lights, exhaust fans and other devices in your RV.
