Suplevel NEMA 10-50P to TT-30R RV Power Adapter Cord, 1ft, 30A 125V, 10AWG STW

The Suplevel NEMA 10-50P to TT-30R adapter cord converts a 10-50P stove or generator outlet to a TT-30R RV socket, delivering up to 30 amps at 125 volts for portable and RV power needs.

Need a simple, heavy-duty way to link legacy 10-50P outlets—found on older stoves, ranges, and some EV charging setups—to TT-30P RV plugs? This 1-foot Suplevel adapter provides a short, robust connection that supports 30 amps (4,750 watts at 125V) and is built from STW-rated 10AWG copper conductors with molded, weather-resistant housings. It’s ETL listed and designed for outdoor use where durability matters.

How does this adapter handle outdoor and RV use?

The cord uses flame-retardant, UV-resistant molded housings and a waterproof sheath to withstand exposure. Nickel-plated brass terminals resist corrosion, while thick copper conductors maintain conductivity under load. It’s compact and short to minimize voltage drop for close-proximity hookups.

• STW 10AWG * 3C copper wire for reliable current flow
• Nickel-plated brass pins and terminals to reduce oxidation
• Molded, flame-retardant housing for outdoor durability
• ETL listed for safety compliance

Will this adapter work with my generator or RV power inlet?

The Suplevel cable pairs a NEMA 10-50P plug with a TT-30R receptacle, making it compatible with 10-50R outlets and TT-30P RV plugs. It’s ideal for connecting generators or older household 10-50 style outlets to RV power inlets and small appliances that accept TT-30P. Verify that your source supplies 125 volts and that your equipment’s maximum current does not exceed 30 amps.

• 10-50P plug fits 10-50R outlets used on some generators and ranges
• TT-30R provides a standard RV/camper connection for 30A, 125V
• Sized for up to 4,750 watts (30A × 125V)
• One-foot length for tight, direct connections

Is this cable safe for high-load applications like welders or EV adaptors?

The cord is constructed for up to 30 amps and is ETL listed, but users should confirm the connected device’s amperage demands. For continuous heavy loads near the 30A rating—such as certain welders or charging setups—ensure proper circuit protection and monitoring. The robust materials and 10AWG conductors help reduce heat buildup under rated loads.

• Supports up to 30A; monitor continuous-load requirements
• 10AWG copper minimizes resistance and heating
• ETL listing indicates tested safety components
• Short length reduces voltage drop for high-current use

What maintenance or precautions should I follow?

Keep connectors clean and dry when not in use, inspect for wear before each hookup, and avoid forcing mismatched plugs. Store the adapter indoors between seasons and replace it if pins or housings show damage. Use the adapter only with appropriate breakers and ground-fault protection where required.

• Inspect pins and housing for corrosion or cracks before use
• Store indoors to prolong UV and weather-resistant materials
• Don’t exceed 30A; use proper circuit protection
• Replace if terminals become loose or visibly damaged

Who this is for: This Suplevel adapter is made for RV owners, contractors, and DIYers who need a short, dependable connection between older 10-50 outlets (stoves, generators, some EV stations) and TT-30P RV inlets or appliances. It suits situations where space is limited and a rugged, weatherproof connector is required—campgrounds, job sites, and backyard generator setups. If you’re using equipment that requires more than 30 amps or 240 volts, choose an appropriately rated cable instead.
