VEVOR 50A Generator Cord & Inlet Box Kit — 10 ft NEMA 14-50P to SS2-50R, Weatherproof with LED Indicator

VEVOR's 50A generator cord and inlet box kit is a ready-to-install 10 ft power hookup that lets you safely connect a portable generator to a house or RV with a NEMA 14-50P to SS2-50R twist-lock connection.

When you need a reliable transfer point for backup power, this VEVOR kit combines a heavy-duty 6/3 + 8/1 AWG STW extension cable, a weatherproof inlet box with indicator light, and a twist-lock receptacle to create a secure generator-to-house feed. It’s engineered for outdoor use, prepped for simple mounting, and ETL listed to meet safety expectations for household and recreational applications.

How does this kit handle outdoor conditions and long-term use?

The cord and inlet box are built specifically for exterior environments: the cable has a flame-retardant PVC jacket and pure copper conductors to limit voltage drop, while the inlet box uses a rust-resistant finish and a flip cover to protect against water and debris. An LED power indicator helps you confirm live power at night or from a distance.

• STW jacket resists bending, rain, and temperature extremes
• Pure copper cores minimize power loss over 10 ft
• Rust-resistant inlet box with flip cover keeps moisture out
• Built-in LED shows when power is present

What do I get in the kit and how does it connect to my generator and house?

The kit includes a 10-foot STW 6AWG/3C + 8AWG/1C extension cord with a NEMA 14-50P male plug, a NEMA SS2-50R twist-lock female receptacle, and a weatherproof power inlet box. You plug the male end into your generator or transfer panel and mount the inlet box on the exterior wall; the twist-lock receptacle ensures a firm, vibration-resistant connection.

• NEMA 14-50P male plug for generator or transfer panel connection
• NEMA SS2-50R twist-lock female receptacle for secure mating
• Pre-drilled inlet box with detachable knockouts for easy wiring
• 10 ft length balances reach with manageable voltage drop

Is installation difficult and what tools or wiring prep are needed?

Installation is designed to be straightforward: the inlet box arrives with pre-drilled mounting holes and removable knockouts so you can route the cable without custom cutting. A spacious interior simplifies wire routing and terminal hookups; basic hand tools and standard electrical connectors are typically all that’s required.

• Pre-drilled holes reduce need for additional drilling
• Detachable knockouts allow neat conduit or cable entry
• Spacious box interior for easy wiring and secure connections
• No specialized tools required for typical installations

How does the twist-lock connector and cord gauge affect safety and performance?

The NEMA SS2-50R twist-lock connector prevents accidental disconnection and improves contact reliability under vibration, while the 6 AWG conductors carry up to 50A with lower heating and line loss than thinner wires. Together they provide a more dependable feed for heavy loads common during outages or when running RV air conditioning and conveniences.

• Twist-lock design resists loosening from movement or vibration
• 6 AWG copper conductors support up to 50A current safely
• 8 AWG grounded conductor ensures stable neutral/ground path
• ETL listing indicates compliance with safety standards

Who is this for: homeowners, RV owners, and contractors who need a compact, durable wiring solution to deliver up to 50 amps of portable power. If you want a preassembled 10 ft generator-to-inlet setup that balances professional features with do-it-yourself ease—weatherproof housing, clear power indication, and a twist-lock connection—this VEVOR kit suits emergency backup, seasonal installations, and on-site power needs.
