1 / 7Nilight 50662RV 50A 15-ft NEMA 14-50P Replacement Cord
The Nilight 50662RV is a 50-amp replacement cord with a NEMA 14-50P plug and a pre-stripped, color-coded wire end. Its 15-foot reach and open end suit repairs or installations where the equipment accepts that plug and the bare conductors can be connected appropriately.

Pros and cons
Pros
- Open wire end may work for replacement or custom wiring where a 14-50P plug and bare conductors are required.
- 15-foot length provides more reach than a short pigtail while remaining manageable for storage.
- Color-coded conductors and a claimed ergonomic plug handle may simplify identification and handling.
Cons
- The wire-end design is not a plug-to-socket extension, so it will not connect directly to equipment requiring a receptacle at the cable end.

What to know before buying
Listing details to confirm
The listing's title describes the cord as an extension cable, while its details and installation description specify an open, pre-stripped wire end. Voltage is listed as 250 in one details field but as 125/250 Volts elsewhere. Confirm the required termination, supply, and equipment rating before purchase. The stated 50 A rating and 12500 watts are manufacturer claims. Connect only to a compatible NEMA 14-50R source. The listing also claims UL listing, but certification is not independently established here.
Who is it for?
A good fit for
- RV or EV equipment repairs that specifically call for a 50 A NEMA 14-50P cord with an open wire end.
- Installations where 15 feet of cable, a 4-color conductor set and a weather-resistant jacket match the project requirements.
Less suited to
- Buyers needing a conventional extension cord with a female NEMA 14-50R end.
- Equipment using a twist-lock, 3-prong or other incompatible outlet connection.

The available aggregate ratings lean positive, with the reported ratings falling in the four- and five-star categories. The small rating sample and absence of written feedback do not show what buyers liked or disliked. Treat this as limited satisfaction evidence, not confirmation of fit, wiring suitability or durability.
Frequently asked questions
Does this cord have a receptacle at the other end?
The listing describes a pre-stripped open wire end, not a female receptacle. Confirm the termination is right for your installation.
What outlet does the plug fit?
It has a NEMA 14-50P plug. The listing says it will not fit twist-lock L14-30 or 3-prong 10-50 outlets.
What is the cord's length and rating?
The listing gives a length of 180 inches and a 50 A rating. Voltage appears inconsistently as 250 in one details field and 125/250 Volts elsewhere, so verify suitability for your equipment.
Does the listing claim weather protection?
Yes. It describes a weather-resistant STW jacket with a flame-retardant PVC sheath, for indoor and outdoor use.
