Watertight Locking Plug L5-30P
The Hubbell HBL28W47 is a watertight locking plug built for industrial environments. It carries a NEMA L5-30P configuration rated at 30 A and 125 V AC single phase. The straight-orientation housing uses yellow thermoplastic elastomer that resists chemicals and impact. It suits crews needing a secure, polarised connection on generators or temporary power distribution.
30 A capacity with screw-terminal wiring
The device handles 30 A continuously through two poles and three blades. Screw terminals accept standard wiring for cables from .375 in up to 1 in diameter. Headroom ends at the 30 A rating; loads beyond that trip upstream protection. It is not for buyers who want higher amperage or multi-phase supply.
Industrial-grade housing and cable range
The yellow TPE shell seals against water ingress while surviving rough handling on job sites. Screw terminals give a repeatable mechanical joint without special tools. The 1 in maximum cable diameter fits common heavy-duty cords, while the .375 in minimum keeps smaller leads secure. It is not for installations requiring panel-mount inlets or angled orientation.

Questions about this item
Will the HBL28W47 plug fit the existing L5-30R receptacle on my generator?
Yes, the NEMA L5-30P configuration matches standard L5-30R receptacles for 30 A 125V AC service.
How can I verify the watertight seal is effective after wiring the plug?
The thermoplastic elastomer housing is rated watertight and chemical resistant; confirm the cable gland compresses evenly on your cord within the 0.375 in to 1 in range.
Does the package include the cord or only the plug body with screw terminals?
The product is the locking plug housing with screw terminals; you must supply a suitable cord of 0.375 in to 1 in diameter separately.
