Understanding the Basics of RV Electrical Hookups

For both novice and experienced RV enthusiasts, understanding the fundamentals of RV electrical hookups is essential for a safe and comfortable camping experience. Whether you’re a full-time RVer or enjoy occasional trips, this guide will walk you through the key aspects of RV electrical systems, ensuring you’re well-prepared to connect to power sources at campgrounds and RV parks.

Electrical System Components:

  1. Power Source: RVs typically rely on one of three power sources – shore power (campground electricity), generator power, or battery power. Shore power is the most common source used for RV electrical hookups.
  2. Shore Power Pedestal: At RV parks and campgrounds, you’ll find shore power pedestals, which provide the electrical connection point for your RV. These pedestals usually offer 30-amp or 50-amp service.
  3. RV Electrical Cord: Your RV is equipped with an electrical cord that connects to the shore power pedestal. The cord may have either a 30-amp or 50-amp plug, depending on your RV’s electrical system.

Understanding Amps and Voltage:

  1. 30-Amp Service: This is a common electrical hookup for smaller RVs and trailers. It provides 120-volt power and is suitable for most appliances and devices found in RVs.
  2. 50-Amp Service: Larger RVs and motorhomes often use 50-amp service, which offers 120/240-volt power. This higher amperage can accommodate more appliances and larger air conditioning units.

Connecting Your RV:

  1. Identify the Power Pedestal: When you arrive at your campsite, locate the shore power pedestal. It typically has a flip-up lid revealing the electrical outlets.
  2. Matching Amps: Ensure that your RV’s electrical cord matches the amperage provided by the pedestal. A 30-amp cord should connect to a 30-amp outlet, and a 50-amp cord should connect to a 50-amp outlet.
  3. Power Off: Before plugging in, switch off the circuit breaker in your RV’s electrical distribution panel.
  4. Connect and Lock: Insert the RV’s electrical cord into the pedestal’s outlet, and then twist it to secure the connection. This prevents accidental disconnection.
  5. Power On: Turn on the circuit breaker in your RV’s electrical distribution panel to activate the electrical supply. Check that power is flowing to your RV.

Managing Your Electrical Load:

  1. Load Management: Be mindful of your RV’s electrical load. Avoid overloading the system by using too many high-wattage appliances simultaneously.
  2. Use Surge Protectors: Invest in a surge protector for added electrical safety. It guards against power surges that could damage your RV’s electrical system.

Safety Precautions:

  1. Weatherproof Connections: Keep electrical connections dry and protected from the elements. Use a weatherproof cover for the power pedestal.
  2. Regular Inspections: Periodically inspect your RV’s electrical cord for signs of wear or damage. Replace it if needed to ensure safety.
  3. Proper Grounding: Ensure your RV is properly grounded to prevent electrical shocks.
  4. Unplug Before Moving: Always disconnect from the power source before moving your RV to avoid damaging the electrical cord or the pedestal.


  1. Tripped Breakers: If the power goes out in your RV, check for tripped circuit breakers in the electrical distribution panel. Reset any tripped breakers.
  2. Check the Pedestal: If you lose power and your RV’s breakers are fine, inspect the power pedestal for any tripped breakers on its side.
  3. Contact Campground Staff: If you encounter persistent electrical issues, contact the campground staff or RV park personnel for assistance.


Understanding the basics of RV electrical hookups is a crucial skill for all RVers. Whether you’re staying at a full-service RV park or boondocking off the grid, having a solid grasp of your RV’s electrical system ensures a safe and enjoyable camping experience. By following the steps for connecting your RV, managing your electrical load, taking safety precautions, and troubleshooting common issues, you can confidently navigate the world of RV electrical systems and make the most of your travels.
