NEMA 10-50 Dryer Cord | Custom Length 50 Amp Range Cord | Custom Power Cable UL Listed
The NEMA 10-50 power cord is a heavy-duty, 3-wire electrical cable designed for high-power appliances such as older electric dryers, ranges, or commercial cooking equipment. It features a 3-prong NEMA 10-50P plug (two hot wires and a neutral, without a separate ground) for connection to a matching NEMA 10-50R receptacle, supporting up to 12,500 watts at 250V. This configuration is typical in homes built before 1996 and is considered obsolete under modern National Electrical Code (NEC) standards, which mandate 4-wire grounding for safety. Despite this, it’s still used for legacy installations or temporary setups like EV charging adapters. Available in various lengths (e.g., 6FT to 50FT), it is UL-listed for reliability and often features STW-jacketed cable for durability in demanding environments.

Applications:
- Replacement cords for legacy electric dryers or ranges in older homes.
- Industrial extensions for commercial kitchens or welding-adjacent setups (with adapters).
- Temporary EV charging (e.g., via smart splitters for shared outlets).
- High-amperage tools in pre-1996 buildings, like large air compressors.
Installation Notes
- Ensure the receptacle is a NEMA 6-50R rated for 50A/250V; do not use with lower-rated outlets.
- For custom cords, specify length and terminations (e.g., bare wire ends or female connector) when ordering from manufacturers.
- Connect hots (black/red) to L1/L2 terminals and green ground to the ground screw; use torque specs from your welder manual.
- Secure with strain relief at the equipment end to avoid loosening.
- Always turn off power at the breaker and use a licensed electrician for permanent installations. Not compatible with 4-prong (NEMA 14-50) without adapters.
