VEVOR 30A Generator Power Cord & Inlet Box 10 ft L14-30, 10 AWG SJTW, Weatherproof with LED

VEVOR’s 30 Amp generator cord and pre-drilled inlet box is a ready-to-install 10 ft L14-30 extension kit that safely routes up to 7,500W from a portable generator to your home or RV.

This kit bundles a heavy-duty SJTW 10 AWG/4C power cable with NEMA L14-30P and L14-30R connectors and a weatherproof, pre-drilled inlet box. Designed for outdoor use, the assembly is built to resist water, cold, and abrasion while keeping connections tidy and secure. The included LED power indicator, detachable knockouts, and storage accessories streamline installation and everyday use.

How does this cord and inlet box connect my generator to a house or RV?

The cord uses standard NEMA L14-30 connectors: a locking male plug (L14-30P) at the generator end and a matching female inlet (L14-30R) inside the inlet box. When wired into your transfer switch or generator-ready panel, it provides a safe, code-compliant path for 125/250V split-phase power.

• 10 ft SJTW 10 AWG/4C cable rated for 30A/7,500W continuous load
• NEMA L14-30P to L14-30R locking connectors for vibration-resistant contact
• Pre-drilled inlet box fits typical exterior mounting and transfer switch wiring

Is this setup durable enough for outdoor and seasonal use?

Yes — the cord has a pure copper core and a flame-retardant PVC jacket engineered for outdoor conditions. The inlet box features a rust-resistant finish and a flip cover to shield the receptacle from rain, snow, and dust.

• Flame-retardant PVC jacket resists bending, moisture, and temperature swings
• Rust-resistant coating and cover protect the inlet when not in use
• LED indicator provides quick visual confirmation of incoming power

What makes installation straightforward for a homeowner or RVer?

VEVOR supplies a pre-drilled inlet box with removable knockouts so you can route conduit or feed cable without specialized fabrication. The box interior offers room for wiring and strain relief, while the storage bag and strap keep the cable organized off-season or during travel.

• Pre-drilled mounting holes reduce on-site drilling and measurements
• Detachable knockouts let you customize cable entry points for your setup
• Included storage bag and PVC strap simplify transport and storage

How do I verify safety and compatibility before use?

Confirm your generator and transfer switch accept NEMA L14-30 connections and that your panel or transfer equipment is rated for 30A at 125/250V. The cord is ETL listed, and the pure copper conductors provide consistent conductivity for reliable operation when used within rated limits.

• ETL listing indicates third-party safety evaluation
• Use only with compatible L14-30 inlet or transfer switch sockets
• Follow local electrical codes and consult a licensed electrician for permanent installations

Who is this for: This VEVOR kit is aimed at homeowners, RV owners, and contractors who need a portable, weather-resistant solution to connect a portable generator to a house or RV transfer system. It suits anyone who wants a pre-assembled, code-friendly 30A connection with durable materials, easy installation features, and compact storage for seasonal or emergency power use.
