MECMO shore power inlet 50A SS2-50P twist-lock flanged receptacle — waterproof UV-resistant

This flanged inlet provides a compact, watertight shore power solution for recreational vehicles and marine craft. The unit accepts standard CS6364/CS6375 connectors and fits a common 2-11/16 inch cutout, making it a straightforward replacement for existing SS2-50 style inlets. Built from UV-resistant materials with nickel-plated conductors and a gasketed flange, it’s engineered to resist sun, rain, and salt spray while keeping your shore power secure.

How does this inlet protect shore power connections outdoors?

The MECMO inlet uses a combination of a sealed flange, a threaded collar, and a full-180° hinged cover to keep moisture and debris out of the electrical connection. Materials and plating are chosen to minimize corrosion in harsh environments, and the twist-lock mating prevents accidental disconnection under tension.

• Integrated gasket seals the flanged base without caulking
• Threaded collar locks to waterproof ring on mating plug
• UV-resistant ABS housing reduces sun degradation
• Nickel-plated copper poles resist corrosion from salt spray

Will it fit my existing RV or marine cutout and wiring?

The inlet is designed to replace standard SS2-50 recessed inlets and fits the common 2-11/16 inch mounting hole. Terminals are clearly labeled and accept a wide range of copper conductor sizes so you can wire it with typical #10–6 AWG shore power cables.

• Flanged mount dimensions match SS2-50 style cutouts
• Accepts #10 through #6 AWG copper conductors
• Clear terminal markings simplify wiring and inspection
• Mounts flush for a neat, low-profile installation

What electrical load and appliances can this inlet support?

Rated for 50 amps at 125/250 volts (up to 12,500 watts), the inlet supplies enough capacity for common RV and boat systems. It’s suitable for powering multiple high-draw devices when connected to a compatible 50A shore power source.

• 50A rating supports air conditioners and large inverters
• 125/250V compatibility for split-phase shore systems
• Twist-lock connection prevents loss of power under load
• Flame-retardant housing reduces fire risk in electrical faults

How simple is the installation and maintenance?

Installation is straightforward for anyone familiar with shore power wiring: the flanged assembly mounts with standard hardware, the gasket eliminates the need for sealant, and the terminals are accessible for secure connections. Routine maintenance is limited to visual inspection and keeping the cover clear of debris.

• Flanged design with built-in gasket avoids external caulking
• Mounts flush for easy replacement of existing inlets
• Screw terminals are accessible and labeled for quick wiring
• Covers hinge 180° and stay open during plug use for convenience

Who this is for: Owners of RVs, campers, motorhomes, boats, and yachts who need a dependable replacement shore power inlet that resists weather and corrosion. It’s ideal for DIY installers and pros replacing damaged SS2-50 style receptacles or upgrading to a more durable, sealed twist-lock inlet for reliable 50 amp shore power.
