Run your 30-amp RV directly from a generator with a 4-prong NEMA L14-30 twist-lock outlet. The Camco 55338 PowerGrip bridges that connection cleanly and safely, with a non-slip grooved handle and ETL-listed construction you can trust at the campsite or job site.
Many portable and standby generators -- including popular models from Honda, Generac, Champion, and Westinghouse -- provide a NEMA L14-30 4-prong twist-lock receptacle as their primary 30-amp output. The problem: your RV shore power cord terminates in a TT-30R female connector, which won't mate directly. The Camco 55338 solves that mismatch in seconds.
Plug the L14-30P male end into the generator's twist-lock outlet, rotate to lock, then connect your RV's shore power cord to the TT-30R female end. No splicing, no adapters-on-adapters, no guesswork. Rated at 125V/3750W and ETL certified to UL standards, this adapter handles the full current draw of a 30-amp RV system.
4-prong NEMA L14-30P male end twists and locks securely into the generator receptacle, preventing accidental disconnection under load.
Standard 30-amp RV female outlet accepts your existing TT-30R shore power cord without any additional adapter needed.
Deeply grooved grip surface lets you insert and remove the adapter firmly even with wet or gloved hands -- a real advantage in rain or cold weather.
ETL listing confirms testing to applicable UL standards. Meets safety requirements for use at campgrounds, RV parks, and temporary generator hookups.
This adapter is specifically for RVers who use a portable or standby generator as a power source. The L14-30 outlet is a 4-wire configuration (two hot legs, neutral, and ground) commonly found on dual-voltage generators in the 3500W-7500W class. If your generator has a round 4-prong twist-lock outlet and you own a 30-amp RV, this is the correct adapter.
The L14-30P plug end provides a 4-wire connection at the generator (2 hot lines, 1 neutral, 1 ground). The TT-30R female end presents a standard 2-wire-plus-ground 30-amp RV connection. The adapter is wired to pass the appropriate conductors, converting the generator's 4-prong output to the 3-prong RV plug standard. This is a one-piece molded adapter -- no loose cord, no separate pigtail.
The L14-30 is a locking, 4-prong receptacle. It is not the same as an L5-30 (3-prong locking), a 14-30R (dryer-style straight-blade), or a 30-amp TT-30 outlet. Check your generator's spec sheet or look at the outlet: L14-30 outlets are round with 4 slots arranged in an arc plus a center notch. If your generator has a 3-prong locking outlet (L5-30), you need a different adapter -- this one will not fit.
This adapter is designed for 30-amp RV systems only. Do not use this adapter to connect a 50-amp RV directly to an L14-30 generator outlet -- a 50-amp RV requires a different wiring configuration and a higher-rated adapter. Confirm your RV shore power cord is TT-30R (30-amp, 3-prong) before purchasing.
Camco makes a wide range of RV power adapters, surge protectors, and extension cords. If you need a 50-amp RV solution, a different inlet configuration, or a power management device, look for Camco's PowerGrip and TastePURE power accessory lines. Part number 55338 is specific to the L14-30P-to-TT-30R configuration.
