NEMA L14-30R Twist Lock Receptacle

This industrial-grade female receptacle provides a locking 30-amp connection at 125/250 volts AC. The twist-lock design prevents accidental disconnection under vibration or load. It is built for generator hook-ups and heavy-duty commercial power distribution.

Upgrading from Straight Blade Connectors

Replaces non-locking 30-amp plugs that can work loose on job sites or during generator operation. The jump is worth it when equipment must stay powered through movement, outdoor exposure or high current draw. The locking mechanism secures the connection without tools.

Fits 3-Pole 4-Wire Grounding Circuits

Requires a matching NEMA L14-30P plug and wiring rated for 30 amps at 60 hertz. The PBT housing resists heat and impact while the pure copper blades ensure low-resistance contact. It frees the installer from worrying about nuisance trips caused by loose pins.

Questions about this item

What size electrical box or panel cut-out does the NEMA L14-30R receptacle require?

The device fits a standard industrial panel opening for a 30-amp locking receptacle; mount it in a compatible NEMA L14-30R cut-out with the four screw holes aligned.

How do I wire the four terminals on the L14-30R, and which step is most often missed?

Connect the two hot wires to the brass terminals, neutral to silver and ground to green; the step most often missed is tightening the ground screw before energising the circuit.

Which parts of the LK-2431F will need inspection or replacement over time?

Check the PBT housing for cracks and the pure copper blades for pitting or discoloration; replace the receptacle if the twist-lock action feels loose or contacts show heat damage.
