Suplevel NEMA 6-50P to TT-30R Adapter Cord — 125V 30A Outdoor-Rated, 10AWG STW

Suplevel's NEMA 6-50P male to TT-30R adapter cord converts a 6-50 weld or EV outlet into a TT-30 RV-style receptacle, delivering up to 30 amps at 125 volts for temporary power connections.

This heavy-duty adapter is built to bridge mismatched shore power and equipment plugs when you need a reliable supply on job sites, at campgrounds, or near portable generators. Constructed with STW 10 AWG triple-conductor cable, nickel-plated brass contacts and a molded, weather-resistant jacket, it’s designed for outdoor use and repeated plugging and unplugging without excessive wear.

How will this adapter power my RV or camper safely?

The cord provides a TT-30R female interface that accepts standard RV/TT-30P plugs while drawing from a 6-50P source rated at 125V and up to 30A. It includes high-conductivity copper conductors and plated terminals to reduce heat and resist corrosion during prolonged use.

• Rated for 125 volts, 30 amps, and up to 4,750 watts handling capacity.
• STW 10AWG * 3C heavy-duty cable for lower voltage drop under load.
• ETL-listed components indicate third-party safety verification.

Can I use this with welding machines or EV chargers?

The NEMA 6-50P plug is commonly found on welders and some electric vehicle charging equipment. This adapter enables those 6-50 outlets to feed a TT-30R, but it’s intended for temporary and compatible loads—verify device ratings before connecting.

• Fits NEMA 6-50R receptacles found on welders and certain EV connectors.
• Adapts that supply to a TT-30R for RVs, trailers, and generator power outlets.
• Not a permanent wiring solution—use for portable or occasional power needs.

What durability features protect the cord outdoors?

Materials and construction focus on longevity in exterior conditions: nickel-plated brass pins resist oxidation, and the molded plug plus UV-resistant jacket help block sun, water, and abrasion. The cord’s flame-retardant and weatherproof sheath helps it hold up through repeated outdoor use.

• Nickel-plated brass terminals reduce corrosion and maintain conductivity.
• Molded, UV-stable housing protects the plug from cracking or fading.
• Water-resistant jacket and flame-retardant materials for safer outdoor deployment.

What comes in the box and what support does Suplevel provide?

The package contains the pre-assembled Suplevel 6-50P to TT-30R adapter cord, ready to plug in without additional wiring. Suplevel backs the cord with customer support and a 24-month warranty for manufacturing defects.

• One Suplevel NEMA 6-50P male to TT-30R female adapter cord, ready to use.
• ETL-listed components and clear electrical ratings printed on the housing.
• 24-month warranty and responsive Suplevel customer service for help.

Who is this for: electricians, welders, RV owners, contractors and outdoor hobbyists who occasionally need to feed an RV, trailer or small appliance from a 6-50 style outlet or generator. If you require a portable, rugged adapter to match a welder or EV-style supply to a TT-30 RV inlet for temporary power, this cord offers a straightforward, safety-minded option—just confirm amperage compatibility before use.
