Watertight Locking Plug L16-30P

This Hubbell watertight locking plug carries a 30 A, 480V AC rating in a three-phase, four-blade NEMA L16-30P configuration. It is built for industrial equipment that requires a secure, polarised connection in wet or chemically harsh environments.

NEMA L16-30P Interface Limits

The locking design prevents accidental disconnection under vibration, yet the device is rated only for the stated voltage and current. It accepts cable diameters from 0.375 in to 1 in, so thicker or thinner conductors cannot be terminated safely.

Thermoplastic Elastomer Housing

The yellow thermoplastic elastomer shell resists impact and chemical exposure while maintaining a watertight seal when mated correctly. Screw-terminal wiring demands careful torque during installation, and the straight orientation suits inline cable runs rather than panel-mount applications.

Questions about this item

Which version of this plug matches my generator outlet?

The NEMA L16-30P configuration is a three-pole, four-blade locking type rated 30 A at 480 V AC. Match it to an L16-30R receptacle on your generator or panel.

What does the 30 A rating mean when I wire this plug?

It means the contacts and terminals are tested to carry 30 amperes continuously at 480 V AC three-phase. Size your cable and breaker for that load.

How does the L16-30P standard limit what I can connect?

The L16-30P standard defines a 480 V AC, three-phase, 30 A locking interface. It only mates with L16-30R receptacles and accepts cable diameters from 0.375 in to 1 in.
