The 50 Amp RV Extension Cord is designed for reliable power extension between RVs, campers, trailers, motorhomes, generators and campground power pedestals.
50 Amp RV Extension Cord — NEMA 14-50P to 14-50R, 10FT
This 10-foot 50 Amp RV extension cord is designed to add practical reach between a standard NEMA 14-50R shore-power outlet, campground pedestal, or compatible temporary 14-50 power source and an RV, travel trailer, camper, or approved equipment cordset. It uses a NEMA 14-50P male plug on one end and a NEMA 14-50R female connector on the other, preserving the full 4-prong L1-L2-N-G configuration required for 125/250V service.
Rated at 50A, 125 / 250VAC, 50/60Hz, and up to 12,500W at 250V, the cord is built for heavy-duty temporary power links where the factory RV shore cord is just short of the pedestal or outlet box. The 10FT / 3.05 m length helps bridge common short-distance gaps without creating excessive slack, trip hazards, or unnecessary voltage-drop concerns.
The cord uses stranded copper conductors for dependable conductivity and flexible handling, combined with a heavy-duty STW thermoplastic weather-resistant portable cord jacket. The black jacket is suited for outdoor use, repeated coiling, campsite handling, driveway use, and temporary power setups where abrasion and moisture exposure are common.
IP65-rated connector housings provide dust-tight protection and resistance to water jets under defined conditions. This supports outdoor-ready use around RV pads, private campsites, cabins, and properly installed 14-50 outlet boxes, but the connectors should not be submerged or left in standing water.
This product is intended as temporary flexible cordage, not as a replacement for permanent wiring. For EV mobile-connector use, generator connections, or equipment applications, always follow the device manual, local electrical code, and safe grounding/transfer requirements.
