RVINGPRO 30 Amp Generator Cord (75 ft) with pre-drilled 30 Amp inlet box is a ready-to-use generator-to-home hookup kit designed for safe, weatherproof temporary power connections.

When you need to connect a portable generator to a transfer switch or inlet safely and quickly, this RVINGPRO kit pairs a heavy-duty 75-foot 30A cord with a pre-drilled, weatherproof inlet box so you can set up an outdoor power inlet without extra drilling or specialized parts. Built with 10/4 SJTW 100% copper conductors and an ETL listing, the set is sized for up to 7,500 watts and includes a protective cap, indicator light and simple mounting options for convenient installation and seasonal storage.

How does this kit keep outdoor generator connections safe?

The cord uses a flame-retardant PVC jacket and a full-copper 10/4 conductor to reduce heat and resist damage from handling. The inlet box is weather-sealed and includes a cap to block rain and dust when not in use, plus an indicator light showing when power is present.

• 10/4 SJTW cable with 100% copper conductors for reliable current flow
• Flame retardant PVC jacket improves abrasion and heat resistance
• Weatherproof inlet box cap keeps moisture and debris out
• Green indicator light shows live power at the inlet

Will this work with my generator and home transfer switch?

The cord terminates in NEMA 14-30P (male) and NEMA L14-30R (female) twist-lock connectors, matching common 30A generator and inlet configurations for 125/250V supplies. It’s intended for portable generators and transfer switches or inlet boxes rated for 30 amps and up to 7,500 watts of load.

• Male plug: NEMA 14-30P — standard for many generators
• Female: NEMA L14-30R twist-lock inlet compatibility
• Voltage: 125V/250V suitable for split-phase systems
• Maximum continuous wattage around 7,500W

How easy is installation and everyday use?

The inlet box arrives pre-drilled with four directional knockouts so you can route wiring from left, right, bottom or rear without additional drilling. The kit includes a storage bag and cable tie for organization, and the inlet’s cap snaps closed for simple weather protection when not connected.

• Pre-drilled holes for quick conduit or cable entry—no drilling required
• Cap with seal for weather protection when idle
• Included storage bag and cable tie for transport and neatness
• Simple visual power indicator for fast confirmation

What certifications and conditions is the kit rated for?

Both the cord and the inlet box are ETL listed for outdoor use, which means they meet recognized safety standards for electrical products. The construction is intended to withstand adverse weather typical of outdoor generator setups, though proper installation and grounding per local codes are still necessary.

• ETL certification for verified safety compliance
• Durable materials for outdoor exposure and seasonal storage
• Designed to perform under typical storm and outage conditions
• Not a substitute for permanent wiring—follow local electrical codes
