Watertight Locking Plug L14-20P
The Hubbell HBL26W74 is a NEMA L14-20P locking plug rated for 20 A at 125/250V AC. It suits industrial and generator connections where a secure, weatherproof inlet is required. The yellow thermoplastic elastomer housing resists chemicals and impact.
Screw Terminals and Cable Range
The plug uses screw terminals for standard wiring and accepts cables from .375 in to .875 in diameter. The watertight seal and polarized blades maintain a reliable connection in wet or dirty environments. The straight orientation simplifies panel alignment.
Capacity and Headroom
The three-pole, four-blade design handles single-phase loads up to the 20 A rating across both voltage legs. It is not suited for applications exceeding 20 A or for three-phase service. Users needing higher current or different NEMA configurations must select another device.

Questions about this item
How often should I re-torque the screw terminals on the HBL26W74 plug to keep the connection watertight?
Check and re-torque the screw terminals after the initial installation and then periodically during routine maintenance to maintain a secure, watertight connection.
What is the first limit reached when the L14-20P plug runs at full load for extended periods?
The 20 A current rating is the primary limit; sustained operation at this level requires cables rated for the load and secure terminal connections to prevent overheating.
How hot does the thermoplastic elastomer housing get when the plug carries 20 A continuously?
The industrial-grade housing is designed to withstand the heat generated at the rated 20 A load; ensure the cable diameter stays within the 0.375 in to 0.875 in range for proper strain relief and sealing.
