RVMATE 30A 4-Prong Generator Cord Kit 50FT with Pre-Drilled Inlet Box, ETL-Certified, 10AWG Copper

This kit combines a heavy-gauge 50-foot extension cable with a purpose-built inlet box so you can set up a dependable 30-amp 125/250V connection without hunting for extra parts. The bundle is ETL certified, uses full-copper conductors, and includes a flip-cover inlet with a visible LED so you can confirm power at a glance. It’s designed for frequent use, cold-weather flexibility, and an easier installation thanks to multiple knockouts.

How does this kit simplify hooking a generator to my RV or panel?

The packaged inlet box plus cord lets you avoid improvising a connection from separate components. The inlet arrives with four pre-scored knockouts and a user-friendly flip cover so you can mount and wire the inlet in minutes. The included 50-foot cord reaches most common generator placements and stores neatly in the supplied bag.

• Pre-drilled inlet box with four directional knockouts for versatile mounting
• 50ft cable length for safe generator placement clear of exhaust and noise
• Storage bag and strap included to keep the cord organized

What safety and durability features should I expect from the cable and inlet?

The cord uses 10 AWG, four-conductor copper wiring and a heavy-duty PVC jacket rated for heat resistance, reducing voltage drop and improving longevity. The inlet box is ETL certified and the flip cover contains a green LED power indicator that lights when power is being received. Materials resist flame and remain flexible in cooler temperatures for easier handling.

• 100% copper conductors (10 AWG) for efficient conductivity
• Flame-retardant, heat-resistant PVC jacket rated up to 60°C working temperature
• ETL-certified inlet and cable for tested safety performance

Will this cord fit my equipment and how do I know it’s compatible?

The cord uses a NEMA L14-30P male plug and a matching NEMA L14-30R female inlet, the industry-standard configuration for 30A 125/250V generator connections. If your generator and transfer panel or receptacle accept L14-30 connectors, this cable will mate directly without adapters. Check nameplate ratings on your generator and devices to confirm 30A service compatibility.

• NEMA L14-30P to L14-30R configuration for 30A 125/250V setups
• Rated 30A and suitable for up to 3750/7500W at appropriate voltages
• Ideal for most portable generators and RV inlet receptacles accepting L14-30

How easy is installation and what hardware is included?

Installation is simplified by the inlet’s pre-scored knockouts and clear cover, so you can choose the feed direction that works best without special tools. The kit ships with the 50-foot generator cord, the inlet box, a storage bag, and a plastic strap to secure the coiled cable. Basic wiring and mounting hardware are typically all that’s needed to finish the job.

• Four true knockouts let you open holes by hand in seconds
• Included storage bag and strap for tidy transportation and storage
• Flip-cover with LED simplifies power verification after hook-up
