Frequently Asked Questions
Common questions about NEMA NEMA L8-30R cords and connectors
The NEMA L8-30R is a NEMA locking connector rated 30 A at 480 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 L8-30P.
The 30 A 480 V NEMA L8-30R is typically used for locking 480 V single-phase industrial motors, pumps and high-voltage equipment. Selecting the correct 30 A 480 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 L8-30R is the locking female receptacle (socket-outlet or cord connector) and accepts only the matching NEMA L8-30P male plug. It is rated 30 A at 480 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 L8-30R mates only within its own 30 A 480 V family. The L8 is keyed for 480 V and must never be interchanged with lower-voltage locking connectors; the contact pattern prevents cross-voltage connection. 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 L8-30R 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. MOQ is typically 200-1000 pieces, samples ship in 7-15 days and bulk production takes 15-20 working days.
