RV Cable Repairs: Shore Cords & Trailer Plugs
Every RV depends on reliable power. From running your air conditioner and refrigerator to keeping your lights and outlets working, your RV’s cables, shore cords, and trailer plugs keep everything connected. When a cable is damaged, corroded, or not functioning properly, it can create serious safety hazards and leave you without power on the road.
At Traveling RV Technicians, we specialize in RV cable repairs, replacements, and troubleshooting. Whether it’s a 30-amp shore cord, a 50-amp plug, or a 7-way trailer connector, we make sure your system operates safely and reliably.
We service all major brands, including Camco, Arcon, Marinco, Valterra, and Coghlan’s, so you can trust that your RV is in good hands.
Why RV Cable Repairs Matter
Your RV’s electrical cables are the lifeline between your rig and external power sources. A faulty shore power cord or 7-way trailer plug can:
Interrupt power to your RV appliances and HVAC system.
Cause shorts, sparks, or overheating.
Create dangerous fire hazards.
Leave your RV batteries undercharged or unprotected.
Keeping your RV power cords, trailer connectors, and wiring in good condition provides peace of mind and ensures your RV electrical system is functioning properly.
RV Shore Power Cords
Most RVs connect to campground pedestals with either a 30-amp or 50-amp power cord. Over time, these cords may show signs of wear, such as cracked insulation, burnt prongs, or frayed ends.
We handle:
30-amp RV plug repairs
50-amp RV plug replacement
Shore power cord rewiring
Repairing burnt or melted connectors
Installing new RV extension cords
Brands like Marinco and Camco are popular choices for durable RV power cords, and we service and repair them all. We work with all cord lengths, from 25 ft to 50 ft heavy-duty extension cords and even 100 ft RV power cords when you need extra reach to a campground pedestal.
RV Extension Cords & Adapters
Sometimes you need to extend your reach or adapt to different power sources. RV extension cords and dogbone adapters make that possible, but when they fail, they can create serious issues.
We repair and replace:
Heavy-duty RV extension cables
15-amp to 30-amp adapters
30-amp to 50-amp adapters
Surge protector connections
We also ensure every adapter is paired with the right surge protector and amp rating, keeping your RV’s electrical system safe when plugged into different power pedestals.
Camco and Valterra make some of the most common adapters and extension cords in RVing, and we’re experienced in servicing them.
Common RV Cable Problems
Some issues that require immediate service include:
Overheated or melted plugs
Cracked or frayed insulation that reduces flexibility and prevents your cable from staying flexible and durable
Loose or broken connections
Corrosion in contacts
Power surges damaging cables
Ignoring these problems can lead to costly repairs or even total RV electrical system failure.
Preventive Maintenance for RV Cables
Like other parts of your RV, your cables need routine maintenance. We recommend:
Inspecting shore cords and trailer plugs before every trip.
Cleaning prongs and contacts with electrical-safe cleaners.
Checking for heat damage after heavy appliance use.
Replacing worn propane hoses and fittings that run near cables to avoid heat damage.
Brands such as Marinco and Arcon design rugged cables, but even high-quality equipment needs preventive maintenance to stay safe.
Cable Repairs vs. Replacements
Not every problem requires a new cable. Sometimes a burnt plug or a damaged section of cord can be repaired without replacing the entire length. Other times, replacement is the safest option.
We’ll inspect your system and recommend the most cost-effective solution, whether that’s a simple repair or a full RV power cord replacement.
Safety First: Proper Cable Use
Using your RV cords and plugs properly helps prevent future problems:
Always match your RV’s amperage (30A or 50A) to the campground pedestal.
Don’t overload extension cords with appliances.
Use surge protectors to guard against faulty campground wiring.
Coil and store cables properly to avoid kinks or cracks.
Coghlan’s cable storage solutions are a great option to keep your cords organized and protected.
