Miller 281338 Field GFCI Receptacle Kit

The Miller 281338 Field GFCI Receptacle Kit is an OEM accessory designed to retrofit compatible Miller engine-driven welders with ground fault circuit interrupter protection on their 125-volt, 20-amp auxiliary power receptacle. On many construction sites, OSHA regulations and local electrical codes mandate GFCI protection on all temporary power outlets, including those built into portable welding machines. This kit provides a straightforward path to compliance by replacing the welder's existing standard receptacle with a GFCI-protected version, allowing operators to safely run power tools, lights, and other equipment from their welder's auxiliary output.

The plug-in connector design is intended for field installation, meaning welders can be upgraded on-site rather than taken out of service for a shop visit. The kit is rated at 20 amps and 125 volts, matching the auxiliary power specifications of compatible Miller machines. As a genuine Miller part, it is engineered to integrate properly with the welder's electrical system, ensuring reliable trip characteristics and consistent protection. Before purchasing, it is important to verify that your specific Miller model supports this kit, as not all machines share the same receptacle configuration.
