Understanding Your RV's Power Systems
RVs have two separate electrical systems that work together:
120-Volt AC System
This powers your air conditioner, microwave, household outlets, and TV. It works just like your house and requires you to be plugged into Shore Power or running a Generator.
12-Volt DC System
This powers your lights, water pump, fans, and furnace controls. It runs off your House Batteries. When plugged in, a Converter charges your batteries and powers 12V items.
Common Culprits
- GFCI Outlets: One tripped GFCI in the bathroom can kill power to the kitchen and outside outlets.
- Battery Disconnect: Often bumped accidentally, killing all lights and 12V power.
- Pedestal Breakers: Always check the campsite power pole first!
