RV Extension Cords

Choose length based on the distance from the shore power pedestal to your RV and allow extra slack; common lengths are 15–50 feet. Select gauge by amperage: use 12 AWG or heavier (10 AWG) for 30 amp circuits and 10 AWG for 50 amp circuits to minimize voltage drop

Check your RV's power inlet or owner's manual for the required amperage; travel trailers often use 30A while larger motorhomes use 50A. Match the cord's plug and receptacle configuration to your RV and campground pedestal

Look for heavy-duty, outdoor-rated jackets (e.g., SOW/SOOW), molded strain reliefs, weatherproof covers for connectors, and corrosion-resistant prongs. Some cords include built-in circuit protection or integrated surge protection devices, but surge protection is also commonly provided by a separate inline protector

Surge protectors guard against voltage spikes while electrical management systems can protect against miswired pedestals, low/high voltage, and open neutral/ground conditions; both improve electrical safety but are separate from the extension cord itself

Keep the cord clean and dry before storage, coil it loosely without tight kinks, avoid dragging it across rough pavement, and inspect connectors and insulation regularly for cracks or corrosion. Store in a ventilated, temperature-moderate location away from direct sunlight

Expect budget options under $50 for basic 30A cords and mid-to-higher-quality 30A or 50A cords typically ranging from $50 to a few hundred dollars depending on length, gauge, and added features such as integrated surge protection

No; household extension cords are not rated for the amperage, outdoor use, or pin configurations required by RV shore power. Use purpose-built RV extension cords sized to your RV's amperage rating and outdoor electrical standards
