LORDWORLD LK-7431 NEMA L14-30R 30A 125/250V 3-Pole 4-Wire Receptacle

Industrial Locking Receptacle

The LORDWORLD LK-7431 is a NEMA L14-30R female receptacle rated for 30 amps at 125/250 volts AC. It provides a twist-lock connection for industrial and commercial equipment requiring a secure 3-pole, 4-wire grounding configuration. The UL and CUL certified housing uses non-slip nylon and PBT plastic with pure copper terminal blades. It supports rewirable installation for power cables up to 10 AWG.

30-Amp 125/250V Rating

The single specification that determines compatibility is the NEMA L14-30R standard delivering 30 amps across both 125 volt and 250 volt circuits at 60 hertz. This 3-pole, 4-wire grounding arrangement suits generators, transfer switches and heavy-duty machinery needing a locking plug. Builders needing a different amperage, voltage or pin configuration must select a matching NEMA designation.

Thermals And Power Draw

The pure copper terminals minimise resistive heating while the nylon and PBT housing resists heat deformation under continuous 30-amp loads. No active cooling is required because the device is a passive connector without electronics. Normal operation produces no audible noise. Power draw depends entirely on the connected load rather than the receptacle itself.
