This heavy-duty adapter cable bridges that gap by linking a marine SS2-50P (twist-lock) shore inlet to a 14-50R 4-prong RV\/EV outlet, supporting up to 50 amps and both 125\/250 volts. Built with molded grips and 10 AWG copper conductors, it’s designed for secure connections in wet or high-use environments without modifying existing shore or vehicle wiring.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this adapter handle 50 amp shore power safely?\u003c\/h3\u003e\n\n\u003cp\u003eThe MECMO adapter is rated for up to 50 amps and 125\/250 volts, using STW 10 AWG copper conductors and molded housings to reduce strain and exposure. The twist-lock SS2-50P male plug and the 14-50R female receptacle are built for repeated insertion and removal while maintaining a tight, low-resistance connection.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e50A max load, 125\/250V capacity for shore, generator, or EV\/RV use\u003c\/li\u003e\n  \u003cli\u003eSTW-rated 10 AWG copper wire for consistent current flow\u003c\/li\u003e\n  \u003cli\u003eMolded grips and locking ring for secure, weather-tolerant coupling\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this let me plug an RV or Tesla EV into a marina power post?\u003c\/h3\u003e\n\n\u003cp\u003eYes — the adapter accepts a marine SS2-50P twist-lock shore plug and provides a 4-prong 14-50R receptacle compatible with many RVs and Tesla EV charging cords that use the 14-50 form factor.
