MECMO 14-50P to SS2-50R RV Adapter 50A 125/250V Twist-Lock Converter — Straight 14-50P to SS2-50R

The MECMO 14-50P male to SS2-50R female adapter converts a 14-50 straight-blade generator outlet to a 50A twist-lock receptacle for safely linking a compatible RV or inlet.

If you need to pair a portable generator that has a 14-50R outlet with an RV shore-power inlet or house transfer switch that accepts an SS2-50P twist-lock plug, this adapter changes the plug form so the connection fits. It does not modify electrical characteristics — voltage, amperage, or waveform remain as supplied by your generator — so confirming ratings before use is essential for safe operation.

How does this adapter connect a generator to my RV inlet?

Attach the straight 14-50P end into the generator’s 14-50R outlet, and insert and twist the SS2-50R twist-lock into the RV or inlet male plug until it locks. Always power down equipment and open circuit breakers before making or breaking the connection to avoid arcing and risk.

• 14-50P male straight-blade end fits into generators with a 14-50R socket.
• SS2-50R female twist-lock accepts a matching SS2-50P inlet or plug.
• Twist-lock action secures the connection under vibration or movement.
• Use only when both devices are rated for 50A, 125/250V split-phase service.

Will this adapter change my generator’s voltage or current?

No — this is a mechanical plug-type adapter only. It changes the physical connector so equipment mates properly but does not step up or step down voltage, limit amperage, or provide surge suppression or regulation.

• Rated for 50 amps and 125/250 volts; supports up to 12,500 watts if source can deliver it.
• Not a converter or transfer switch; do not rely on it to alter electrical properties.
• Never use on systems that are only rated for 30A or non-split-phase configurations.
• Check generator and inlet nameplates for matching 50A ratings before use.

What safety steps should I follow when using this adapter?

Prioritize disconnecting power and opening breakers before connecting or disconnecting the adapter. Proper insertion and locking reduce risk; routine inspection for damage and secure mounting will help avoid loose connections or overheating.

• Turn the generator off and switch off transfer breakers before connecting.
• Push the 14-50P straight plug fully into the generator outlet.
• Insert SS2-50R and twist clockwise to engage its lock mechanism.
• Inspect for melting, cracks, corrosion, or loose pins prior to each use.

Who is this product for? RV owners, campers, homeowners with portable 50A generators, and electricians who need a reliable, simple mechanical adapter to marry a generator’s 14-50 outlet with an SS2-50 twist-lock inlet will find this useful. It’s designed for those who already understand their system’s 50A 125/250V split-phase requirements and need a secure physical connection; it is not appropriate for anyone requiring voltage conversion, power conditioning, or use with 30A-only equipment.
