Why Does My RV Keep Tripping the Breaker?

Why Does My RV Keep Tripping the Breaker?

A frustrating experience indeed! There are several reasons why your RV might be tripping the breaker, ranging from simple overloads to more complex electrical issues. Here are some potential culprits:


  • Exceeding amp limit: Check your RV’s amp rating (usually 30 or 50) and compare it to the amp rating of the outlet you’re plugged into. Ensure you’re not drawing more power than the circuit can handle, especially when running high-consumption appliances like AC or water heaters.
  • Multiple appliances: Turn off all unnecessary appliances before turning on high-demand ones. Consider staggering usage to avoid exceeding the amp limit.

Electrical issues:

  • Faulty wiring: Damaged or loose wiring in your RV can cause shorts and trip the breaker. Look for signs of overheating, burning, or discoloration.
  • Appliance malfunction: A faulty appliance can draw excessive power or leak current, tripping the breaker. Try isolating the culprit by turning on appliances one by one and monitoring the breaker.
  • GFCI outlet issues: If you’re plugged into a GFCI outlet, a slight ground fault in your RV’s electrical system can trigger the outlet’s safety mechanism.

Other factors:

  • Low voltage: Check the voltage coming from the power source. Low voltage can cause some appliances to draw more power, potentially tripping the breaker.
  • Weather conditions: Hot weather can increase the demand on your electrical system, making it more prone to tripping. Consider reducing appliance usage during high temperatures.

Troubleshooting tips:

  • Identify the breaker tripping: Note which breaker in your RV or campground panel trips to narrow down the potential source.
  • Turn off all appliances: Start with all appliances off and turn them on one by one to identify the culprit.
  • Check for GFCI faults: Press the reset button on any GFCI outlets connected to your RV.
  • Visual inspection: Look for signs of damage in your RV’s wiring or appliances.
  • Professional help: If you’re unsure about the cause or uncomfortable troubleshooting yourself, seek help from a qualified RV electrician. There is another article I wrote about >>>>> Why Does My RV Air Conditioner Smell Musty? to learn more about different parts of RVs.

Remember, safety is paramount. If you suspect a serious electrical issue, don’t hesitate to call a professional.

1: Amped Up Adventures: Demystifying Tripped Breakers in Your RV.

Ah, the open road, the wind whipping through your hair, the freedom of the boundless horizon…until BAM! Your RV’s lights flicker, appliances sputter and the dreaded click plunges you into electrical darkness. Yep, you’ve just crossed paths with the infamous tripped breaker, the bane of every RVer’s existence. But before you throw in the towel (or worse, start rewiring with duct tape), let’s untangle this amp-tastic mystery.

Understanding the Jargon:

First things first, let’s ditch the electrician lingo and break it down:

  • Amps: Think of amps as water flowing through electrical wires. The higher the amp rating, the wider the pipe, and the more power it can handle. Your RV usually has a 30A or 50A rating, like the size of your garden hose.
  • Volts: Imagine voltage as the water pressure pushing that flow. Higher voltage means a stronger push, but too much can burst the pipe (think fried circuits!). Standard shore power is 120V, like city water pressure.
  • Watts: Watts are like the work your appliances do with that water/electricity mix. A high-powered AC unit is like a thirsty lawn sprinkler, guzzling more watts than a simple reading lamp.

The Amp vs. Appliance Tango:

Now, imagine your RV’s electrical panel as a bustling city center, with each appliance a demanding resident. Every time you switch on that AC or microwave, they tap into the main power line, drawing their required “amp-bucks” to function. But there’s only so much to go around! So, if everyone tries to withdraw at the same time (think rush hour!), the system overloads, and the breaker (our trusty traffic cop) throws the switch, cutting off the power to prevent a meltdown.

Table 1: Common Amp Hogs in Your RV:

ApplianceApproximate Amp Draw
Air Conditioner13-15 A
Microwave7-11 A
Water Heater (Electric)10-12 A
Hairdryer8-14 A
Coffee Maker8-12 A

Pro Tip: Keep track of your amp usage! Many RV panels have meters, or you can invest in a handy portable amp meter. Seeing those numbers climb can be a real-time power play, helping you prioritize appliances and avoid the dreaded trip.

Part 2: When Amps Go Rogue: Diagnosing the Tripped Breaker:

So, your breaker’s thrown a tantrum. Now what? Don’t panic! Grab your detective hat and let’s crack this case:

The Usual Suspects:

  • Overload: Did you accidentally turn on the hair dryer while the AC was blasting? That’s a recipe for overload! Check which appliances were running when the breaker tripped and try a staggered approach to avoid exceeding your RV’s amp limit.
  • Faulty Wiring: Sometimes, wires get loose, worn, or even damaged, like a kinked garden hose. This can disrupt the flow and even cause sparks, so keep an eye out for any suspicious burns or discoloration around your RV’s electrical system.
  • Appliance Malfunction: Maybe your trusty AC unit has developed a power-guzzling gremlin. Try isolating the culprit by turning on appliances one by one and monitoring the breaker. A faulty appliance might need repair or replacement.

Beyond the Basics:

  • Low Voltage: Sometimes, the problem isn’t your RV, but the source itself. A weak campground outlet or a long extension cord can cause the voltage to drop, making appliances work harder and drawing more amps. Check the voltage at the source and consider alternative power options if needed.
  • GFCI Gremlins: These special outlets have a built-in safety switch that trips if it detects even the tiniest electrical leak. While annoying, it’s a good thing! Try resetting the GFCI and identifying the source of the leak, which could be a faulty appliance or even moisture in the outlet itself.

Remember: When in doubt, don’t hesitate to call a qualified RV electrician. They’re the electrical superheroes who can diagnose and fix even the trickiest amp-tastic troubles.
