Watertight Locking Plug L5-15P 15A
This Hubbell locking plug is a two-pole, three-wire device rated for 125V AC at 15 amps. It is built for industrial environments where watertight and weather-resistant connections are specified. The NEMA L5-15P configuration helps maintain connection integrity in demanding settings. Electricians and maintenance teams specify it for equipment that must stay powered in wet or dusty conditions.
IP69K rating and cord range
The housing carries an IP69K ingress-protection rating, meaning it resists high-pressure water jets and dust ingress. It accepts cable diameters from .375" to .625" and wire sizes from 16/3 SJ to 10/3 SJ plus 18/3 S to 12/3 S via screw terminals. These ranges let the same plug serve multiple cord sets without adapters. Installers can terminate approved cables directly in the field.
Thermoplastic elastomer body
The smooth thermoplastic elastomer body is designed for easy cleaning and minimal debris collection. Valox components and stainless steel hardware at connection points add corrosion resistance. The plug operates continuously from -40°C to +60°C. UL Listed for Types 4, 4X, 12, 6 and 6P, and compliant with ANSI, NEMA WD-1 and WD-6 standards.

Questions about this item
Will the IP69K seal on this L5-15P plug need periodic replacement?
The plug housing is moulded from thermoplastic elastomer with Valox components and stainless steel hardware; no user-serviceable seal is identified, so the watertight rating is maintained by the integral body rather than a replaceable gasket.
What is the first limit reached when this 15 A plug runs continuously at full load?
The continuous operating temperature ceiling is +60 °C; the nickel-plated brass blades and screw terminals are rated for 15 A at 125 V AC, so the thermal limit of the housing material is the boundary that appears first under sustained maximum current.
How much heat does the Valox body produce when the plug carries 15 A all day?
At the rated 15 A and 125 V AC the plug dissipates only the contact resistance of the nickel-plated blades and screw terminals; the thermoplastic elastomer and Valox housing remain within their -40 °C to +60 °C continuous range without active cooling.
