056442 - Miller L7-15R Twist Lock Connector Body 15A 277V

Reliable Industrial Power Connection

The Miller 056442 Connector Body is a high-quality electrical component designed to meet the rigorous demands of industrial environments. Built to the NEMA L7-15R standard, this connector body serves as the female end of a twist-lock connection system, typically installed on the end of a power cord or extension cable. It is engineered to handle 277 Volts AC and up to 15 Amps, making it suitable for specific high-voltage lighting, single-phase motors, and welding auxiliary equipment that requires a stable and dedicated power source.

Electrical safety and connection integrity are paramount in MRO applications. The 056442 features a 2-Pole, 3-Wire (2P3W) grounding configuration, ensuring that equipment remains properly grounded during operation. The defining feature of this unit is its twist-lock mechanism. Unlike straight-blade connectors that can easily be pulled out by tripping over a cord or moving equipment, the L7-15R requires the user to insert the plug and twist it to lock it in place. This prevents nuisance disconnects and potential arcing damage caused by loose connections.

Miller Electric utilizes durable materials for the housing of this connector, providing resistance to impact, abrasion, and the general wear and tear found in manufacturing plants and fabrication shops. The internal terminals are designed for secure wire retention, accommodating the appropriate gauge wire for 15A circuits. For facility managers and procurement specialists, stocking genuine Miller electrical accessories ensures compatibility and reliability across your equipment fleet.

Whether replacing a damaged connector on an existing cord set or fabricating new custom power drops for a facility expansion, the Miller 056442 offers the professional-grade performance expected from a top-tier welding and industrial manufacturer. Its specific voltage rating of 277V helps prevent accidental plugging of lower-voltage equipment into high-voltage lines, as the physical configuration is unique to this rating.
