Frequently Asked Questions
Common questions about NEMA NEMA L5-20R cords and connectors
The NEMA L5-20R is a NEMA locking connector rated 20 A at 125 V, 2-pole, 3-wire (grounded), for single-phase circuits. The L-prefix indicates a twist-locking connector that must be inserted and rotated to secure it, preventing accidental disconnection under vibration. The trailing R identifies it as a female receptacle; it pairs only with the matching NEMA L5-20P.
The 20 A 125 V NEMA L5-20R 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 20 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 L5-20R is the locking female receptacle (socket-outlet or cord connector) and accepts only the matching NEMA L5-20P male plug. It is rated 20 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 20 A plug is inserted.
No. NEMA connectors are keyed by voltage, current, phase and grounding, so the NEMA L5-20R mates only within its own 20 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.
Yes. We manufacture UL/cUL and ETL listed NEMA L5-20R cord sets, rewireable plugs and receptacles, and molded connectors using RoHS, REACH, PAHS and Proposition 65 compliant cable, with custom lengths, wire gauges, jacket colors, strain relief and labeling.
