FAQs
To install the Eaton GFI12A166 on a job site, start by confirming power is off and inspecting the cord and plug. Connect the unit to the tool or circuit with the locking L5-20 plug using the #12 AWG cord, place it on a stable surface, and ensure the enclosure seal remains intact. Use the test and reset functions to verify operation and label the outlet for safety compliance.
Yes. The GFI12A166 is designed for outdoor and wet environments thanks to its NEMA 4X watertight enclosure and NEC-compliant construction. It provides reliable ground-fault protection while resisting rain, splashes, and dust. Note that it should not be submerged; place it away from direct water jets and ensure proper cord management.
Key specifications include a 20A amperage rating, 120V operating voltage, a 2 ft cord length with a #12 AWG conductor, NEMA configuration L5-20, NEMA 4X enclosure, locking plug type, polycarbonate housing, and automatic reset function. These factors influence safety performance, compatibility with portable power setups, and installation practicality on site.
Yes. The GFI12A166 uses a locking L5-20 plug to maintain a secure connection even in mobile or vibration-prone environments. It ships with a 2 ft (0.61 m) cord made from #12 AWG conductors, balancing manageability with sufficient current capability for typical tools and temporary outlets on rugged sites.
Maintenance is minimal due to its rugged polycarbonate housing and NEMA 4X enclosure, which resist environmental wear. The immediate fault isolation from 20A GFCI protection reduces downtime and potential shock incidents, delivering a faster return on investment through safer operations, less tool damage, and lower lifecycle costs on demanding work sites.
