ELEGRP 50 Amp to 30 Amp RV Adapter Cord

ELEGRP's 12" 50 Amp to 30 Amp RV adapter converts a NEMA 14-50P campground pedestal to a TT-30R RV inlet, delivering a rugged, weatherproof short 'dogbone' solution for safe campsite power.

When you pull into a site that only has a higher-capacity 50A pedestal, this compact adapter lets a 30A RV plug into 50A service without rewiring or bulky gear. Built with 10/3 AWG pure copper conductors, a weather-resistant STW jacket, and multiple safety enhancements from ELEGRP, it’s designed for repeated outdoor use and straightforward hookups.

How does this adapter protect against overheating and outdoor wear?

The cord integrates ELEGRP’s PBE Protection technology, which combines Overheat Protection (OHP) and Weather Water Resistance (WWR) to reduce thermal risk and block moisture intrusion. Materials and construction focus on stability under continual load and exposure.

• OHP reduces heat buildup during extended use.
• STW jacket resists UV, abrasion, and moisture for outdoor durability.
• 10/3 AWG pure copper ensures efficient conductivity and minimal voltage drop.

Will it fit my RV and campground pedestal safely?

This adapter mates a NEMA 14-50P male (50A, 125/250V) to a TT-30R female (30A, 125V), allowing a 30A RV cord to draw from a 50A source while respecting connection types. It’s UL-standard compliant, constructed to handle the rated amperage and voltage without compromising safety labeling.

• Connects 14-50P pedestal to TT-30R RV inlet without modification.
• Rated 30A / 125V / 3750W for compatible loads.
• UL specification tested for reliable performance and safety assurance.

How easy is it to plug in, remove, and store?

The short 12-inch dogbone format keeps the adapter compact and eliminates excess cable clutter between pedestal and RV. Ergonomic grip handles on both ends make insertion and removal quick and reduce strain on hands and connections.

• Ergonomic finger grips for secure, tool-free operation.
• 12" length is compact for tidy storage and minimal trip hazards.
• Heavy-duty molding protects terminals from impact and wear.

What materials and build details support long-term performance?

ELEGRP uses a flame-retardant, heat-resistant STW PVC sleeve combined with 100% copper conductors to balance flexibility, thermal resistance, and conductivity. The adapter is assembled to withstand campground conditions and frequent plugging cycles.

• 100% pure copper wiring for optimal current flow and low resistance.
• Flame-retardant STW jacket for weatherproofing and heat tolerance.
• Rugged molded ends protect against moisture and mechanical stress.

Who is this for: This adapter is aimed at RV owners, travel trailer and camper users, and campsite operators who need a dependable, compact solution to use a 30A RV inlet with a 50A pedestal. It’s appropriate for those who prioritize durable construction, safety-tested components, and an easy-to-handle form factor for frequent travel and seasonal camping.
