Typically, RVs come equipped with either a 30 amp or a 50 amp electrical system. The majority of RVs are equipped with a 30 amp electrical system. Using the 30 amp electrical system in your RV is quite different than using a 200 amp electrical system at home.
Before we get immersed in the topic, I think it is important to review some very basic electrical formulas. If you understand these simple formulas you will begin to understand why a circuit in your RV, or at the campground electric pedestal, is overloaded.
Watts / Volts = Amps
Amps X Volts = Watts
Watts /Amps = Volts
These basic formulas can be used to answer questions based on what information is available at the time. If you have two pieces of information you can solve any electrical equation dealing with your RV’s electrical system.
