GE U050 Unmetered Power Outlet 10-50R 50 A 120/240V AC NEMA 3R

Purpose and Rating

The GE U050 is an unmetered surface power outlet rated for 50 A at 120/240V AC with a NEMA 10-50R receptacle. It is built for high-current single-phase connections where metering is not required. The steel housing carries a NEMA 3R enclosure rating for outdoor or damp locations. This device suits installers needing a direct, unmetered feed for large loads.

Suitable Installations and Limits

This outlet fits applications such as RV hook-ups, welders, ranges or other 50 A 120/240V equipment that use the 10-50R configuration. It is not for circuits requiring over-current protection at the device, because no circuit breaker is integrated. Buyers who need a metered connection, a different NEMA pin layout, or a lower amperage rating should look at other wiring devices.

Build Integration

The steel enclosure mounts on a surface and provides NEMA 3R protection against rain and sleet, so it can sit outside or in a garage without a separate weatherproof box. Because the unit supplies only the receptacle, the installer must provide upstream over-current protection and suitable conductors for 50 A service. The transparent cover allows visual confirmation of the connection status while keeping the contacts shielded.
