Description
RM50DFPB-22 50 Amp RV / Outdoor Power Outlet Box
The RM50DFPB-22 is a hardwired, heavy-duty 50 Amp RV / Outdoor Power Outlet Box built around the industry-standard NEMA 14-50R receptacle. It provides a 125 / 250V AC, 3-pole / 4-wire connection point for RV shore power, travel trailers, motorhomes, portable EV charging units, generators, and outdoor power taps.
The unit uses a steel housing with a painted finish for improved impact resistance and exterior durability compared with lightweight plastic alternatives. Its flip / swing protective cover is padlockable when the plug is engaged, helping reduce accidental unplugging, casual cord removal, or unauthorized power use.
Designed for wall or post mounting, this outlet box is suitable for indoor or outdoor-capable installations. Weather resistance depends on correct mounting, conduit sealing, drainage, and use of appropriate fittings or gaskets at the knockout entries.
The RM50DFPB-22 is intended for hardwired installation through conduit or jacketed cable into KO openings. It is commonly used with #4 AWG to #8 AWG copper conductors, subject to local electrical code and AHJ requirements. A dedicated 50A 2-pole branch circuit should be sized and installed by a qualified electrician.
With ETL Listed safety compliance, a spacious steel enclosure, and a standard 14-50R interface, the RM50DFPB-22 offers a clean, code-conscious shore-power or 50A outdoor receptacle point for residential, workshop, ranch, campsite, and utility applications.
