RVINGPRO 50 Amp Generator Cord 30FT with Inlet Box 🔌

This heavy-duty 50 amp generator cord and inlet box combo brings portable power hookup and a weather-resistant inlet solution for RVs, cabins, and backup generators. The 30-foot cord uses 100% copper conductors and a flame-retardant PVC jacket to deliver up to 12,500 watts at 125/250V, making it practical for powering essential circuits during an outage or for campsite use.

Key Points

The kit includes a 30 ft NEMA 14-50P to SS2-50R twist-locking cord, a pre-drilled 50 amp inlet box, a 50A adapter plug, a cable tie, and a storage bag. The cord is built with STW 6/3 plus 8/1 AWG wiring that the manufacturer specifies for robust current capacity and flexibility. The inlet box arrives with four pre-drilled knockouts positioned left, right, bottom, and rear to allow multiple routing options and avoid extra drilling. Both the cord and inlet box are ETL listed for outdoor use, which the manufacturer indicates supports safe operation in adverse weather.

Benefits

This combo reduces setup time by pairing a ready-made cord with a pre-drilled inlet box, so you can route power to a transfer switch or panel without fabricating entry points. The twist-lock connector on the female end helps maintain a secure connection and resists accidental disconnection during generator runtime. There is also an ergonomic finger grip on the male plug that makes inserting and removing the plug less strenuous, particularly in cold or wet conditions. A green indicator light on the inlet box cap gives a quick visual confirmation when power is present.

Usage Recommendations

For safer installations, mount the inlet box where it is protected from direct spray but still accessible for plugging and unplugging the cord. The pre-drilled knockout locations allow routing into a transfer switch or subpanel from several approaches, which can simplify neat cable runs. Keep the cord coiled in the provided storage bag when not in use to protect the jacket and avoid kinks. Consider that extension beyond 30 ft can increase voltage drop for heavy loads, so plan generator placement and load distribution accordingly.

Note that the package contents can vary by production batch and the adapter plug may not always be included. If precise compatibility or local code compliance is required, verify connections and ratings against your transfer switch or panel specifications before use.
