Description

50 Amp RV Extension Cord | NEMA 14-50P to 14-50R 10FT STW Copper IP65

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.

NEMA 14-50P male to NEMA 14-50R female connection for standard 50A RV shore-power extension use.
4-prong L1-L2-N-G configuration preserves the full 125/250V power path from source to load.

10FT / 3.05 m cord length helps solve short-reach pedestal, driveway outlet, and temporary 14-50 connection issues.
Stranded copper conductors provide reliable conductivity and flexible handling during repeated use and coiling.
Heavy-duty STW thermoplastic weather-resistant jacket supports outdoor portable cord applications.
IP65 connector housings are dust-tight and water-jet resistant under defined conditions; not immersion-proof.
Black outdoor jacket is built for campsite, driveway, private pad, and temporary equipment power setups.
Suitable for RVs, travel trailers, campers, generator/equipment temporary 14-50 links, and approved temporary outdoor 14-50 applications.
Can be used with certain EV mobile-connector setups only when allowed by the EVSE manual and local code.
Short 10FT format helps reduce excess slack, trip hazards, and unnecessary coil heat compared with oversized cords.

Frequently Asked Questions

Q1: Will this work with my RV's shore-power cord?

A: Yes, if your RV uses a standard 50A shore cord with a NEMA 14-50P plug. The RV plug inserts into this cord's NEMA 14-50R female end, and the male NEMA 14-50P end plugs into a matching NEMA 14-50R receptacle or outlet.

Q2: Is 10 feet long enough?

A: For many short-reach campground pedestals, driveway outlet boxes, and similar 14-50 connections, 10FT provides extra reach without excessive slack or unnecessary voltage-drop concerns. If more reach is repeatedly required, use a single properly rated longer cord or relocate the outlet instead of stacking extensions.

Q3: What does IP65 mean on this cord?

A: IP65 on the connector housings means dust-tight protection and resistance to water jets under defined conditions. It does not mean the connectors are immersion-proof, so keep mated ends elevated, off wet ground, and away from standing water.

Q4: Can I use this with a generator?

A: Only use it with a generator that provides a correctly wired and grounded NEMA 14-50R connection, and follow applicable transfer, isolation, neutral/ground bonding, and local code requirements. Never back-feed or improvise wiring.

Q5: Can I use this for EV charging?

A: Treat EV use as temporary and follow the EVSE or vehicle manual first. Many EVSE manufacturers discourage or restrict extension cords. Use only if your equipment allows it, with a dedicated correctly grounded 14-50R outlet, the cord fully uncoiled, and connections kept dry and off the ground.

Q6: Can I daisy-chain two 14-50 extensions to get more length?

A: Daisy-chaining is not recommended because every additional contact point can become a heat or failure point. Use a single properly rated cord of the correct length or have a licensed electrician place a 14-50R outlet closer to the load.

Q7: Can I run this cord through a window, wall, or under a rug?

A: No. This is a flexible cordset for open-air, visible, temporary use. Running it through walls, windows, ceilings, under rugs, or as permanent wiring can create fire and shock risks.

Q8: What should I check before plugging in?

A: Check that the jacket and plugs have no cuts, crushed areas, melted spots, or bent prongs; confirm the upstream outlet is properly wired; make sure the plug seats firmly; and keep the cord uncoiled and away from sharp edges or standing water during use.
