NEMA L5-30R Female Twist Locking Receptacle American Power Cord, 30A, 125V, UL/cULus/ETL Certified

The 30 A 125 V NEMA L5-30R is typically used for locking 125 V connections for generators, RVs, temporary power, lighting and equipment where the cord must not vibrate loose. Selecting the correct 30 A 125 V locking connector ensures the contacts and cable can carry the load without overheating and that the single-phase supply is connected with the proper grounding and polarity.

The NEMA L5-30R is the locking female receptacle (socket-outlet or cord connector) and accepts only the matching NEMA L5-30P male plug. It is rated 30 A at 125 V in a 2-pole, 3-wire (grounded) configuration, and it supplies power to the connected cord or equipment only when the correctly keyed 30 A plug is inserted.

No. NEMA connectors are keyed by voltage, current, phase and grounding, so the NEMA L5-30R mates only within its own 30 A 125 V family. The locking L5 is the twist-lock 125 V counterpart of the straight-blade 5-series and is not interchangeable with the non-locking TT-30 RV connector despite both being 30 A 125 V. When two configurations must be joined, use a properly rated, UL-listed adapter or cord set, and never exceed the lowest current rating in the chain.
