173556 - Miller 32A 130V Flange Mount Receptacle 2P3W

Technical Overview of the Miller 173556 Receptacle

The Miller 173556 is a specialized electrical receptacle designed for use within the auxiliary power systems of industrial welding equipment. As a genuine Miller Electric OEM part, this component is engineered to meet the rigorous electrical and mechanical standards required by heavy-duty welding generators and power sources. The unit features a straight body configuration with a flange mount, specifically designed for panel installation where secure retention is critical to withstand the vibration and physical stress common in mobile and industrial welding environments.

Electrically, this receptacle is rated for 32 Amperes and 130 Volts. It utilizes a 2-Pole, 3-Wire (2P3W) grounding configuration, which is essential for ensuring operator safety and proper equipment grounding during operation. The 130V rating typically aligns with yellow color-coding standards in industrial contexts (often IEC 60309 standards for 100-130V applications), indicating its use for standard auxiliary power delivery. The flange mounting system provides a robust interface with the machine's chassis, preventing the receptacle from loosening during plug insertion and removal cycles.

Replacing a damaged or worn receptacle with the correct OEM part is vital for maintaining the integrity of the machine's electrical system. Generic replacements may not match the specific flange dimensions or thermal properties required by Miller equipment. The 173556 ensures that the contact pressure on the mating plug remains within tolerance, reducing electrical resistance and the associated risk of overheating. This component is supplied as a single unit, ready for installation into the existing wiring harness of compatible Miller power sources.

Technicians should verify the specific wiring diagram of the host machine before installation to ensure proper phase and ground termination. This receptacle is designed to handle the inductive loads often associated with power tools run off welder generators, providing a durable and reliable connection point for job site peripherals.
