30A Watertight Locking Connector L5-30R

This 30-amp 125V AC single-phase connector serves industrial and commercial sites that require a watertight locking interface. The NEMA L5-30R configuration accepts cable diameters from .375 in to 1.125 in and wire sizes from 12/3 SJ up to 8/3 S. It is built for environments where moisture ingress must be prevented.

Sustained load behaviour across temperature extremes

The thermoplastic elastomer body with Valox components and stainless steel hardware operates continuously from -40°C to +60°C. NEMA 4, 4X, 6, 6P and IP69K ratings confirm resistance to moisture ingress during prolonged exposure. Corrosion-resistant materials maintain electrical integrity under continuous rated current.

Installation practicalities and common issues

Screw terminal wire connections simplify field wiring within the stated cord accommodation range. The smooth body design allows easy cleaning during washdown procedures. Installers must verify that cable diameter and wire gauge fall inside the .375 in to 1.125 in and 12/3 SJ to 8/3 S limits to achieve a compliant seal.

The connector is rated for continuous operation between -40 °C and +60 °C, so it handles a sustained 30 A load without overheating.

What cable and wire sizes must I already have to terminate this L5-30R connector?

It accepts cable diameters from 0.375 in to 1.125 in and wire sizes from 12/3 SJ up to 8/3 S.

Will this watertight connector fit the older L5-30P inlets on my existing generator panel?

Yes, the NEMA L5-30R locking configuration mates directly with any standard L5-30P plug or inlet.
