FAQs
The GFI12M121 uses a locking L5-20 plug and ships with a 2' (0.61 m) cord of #12 AWG. This configuration offers a compact, easily managed portable outlet for close-quarters work while still delivering reliable 20A protection. The locking plug helps prevent accidental disconnections during busy site operations, improving reliability in temporary power setups.
The unit uses a ground fault circuit interrupter (GFCI) to detect ground faults and trip the circuit quickly, reducing shock risk. A 20A rating indicates the maximum continuous current the outlet can safely deliver before protection trips. In wet environments, this combination minimizes exposure to electrical hazards while maintaining performance for typical portable tools and equipment.
Yes. The NEMA 4X enclosure provides watertight and corrosion-resistant protection, making it suitable for outdoor construction sites and damp or coastal environments. The unit’s manual reset and locking plug add safety and reliability, ensuring controlled re-energization after trips and secure connections in demanding field conditions.
Key compliance features include the GFCI protection and the NEMA 4X enclosure rating, which denotes watertight and corrosion-resistant protection. These characteristics support safety standards for temporary power on worksites and in wet areas. The locking L5-20 configuration further enhances reliability by maintaining secure connections in mobile deployments.
Regularly test the GFCI function, inspect the gasket and locking plug for wear, and store the unit in a dry environment when not in use. Routine checks help prevent unexpected trips and extend life in harsh sites. The lightweight design and compact footprint also reduce handling time and transport costs, improving overall return on investment.
