The inlet or the receptacle is factory fitted to the enclosure, so the installer only brings the feeder to the terminals inside. Cover, gasket and plugged cable entries are supplied with the box.

An RV power outlet box gives a trailer or a motorhome a place to plug in away from a campground. The TT-30R receptacle takes the 30 amp RV cord, and the 5-20R duplex next to it runs a vacuum, a light or a charger without unhooking the coach.
Both receptacles are 125V. The TT-30R is the travel trailer standard and nothing else fits it, which is why the box carries the pair: one connector for the coach, one general purpose outlet for everything else at the parking spot.
Driveways and side yards where a trailer is stored and topped up, small campgrounds and farm pads, workshops that host a camper, and job sites that need a 30 amp outlet plus ordinary 120V receptacles on one post.
Feed the box from a dedicated 30 amp circuit. The 5-20R receptacles need GFCI protection where the box is outdoors, and a TT-30R supplied from the same circuit is protected by the branch breaker.
Mount the box at a height that lets both cords hang with a drip loop, and close the cover over the cords rather than leaving it open against the wall so rain does not sit on the receptacles.

Common questions about 30 Amp RV Power Outlet Box, NEMA TT-30R and 5-20R Duplex
Ordinary 120V loads at the parking spot: a vacuum, a drill, a light or a phone charger. It saves unhooking the coach cord every time something else needs power at the trailer.
From a dedicated 30 amp circuit with a breaker sized for the conductors, and with GFCI protection for the 5-20R duplex when the box is outdoors. The TT-30R is covered by the branch breaker on the same circuit.
Yes. The enclosure has pre-drilled mounting holes, so it goes onto a wall, a post or a pedestal. Mount it high enough that both cords hang free with a drip loop below the cover.
The cover closes over the plugged-in cords and the gasket seals against the enclosure, so the receptacles are covered while the box is in use. That is the point of the deeper cover: it is designed to be shut with the cords in place.
