Frequently Asked Questions
Common questions about NEMA NEMA L14-30P cords and connectors
The NEMA L14-30P is a NEMA locking connector rated 30 A at 125/250 V, 3-pole, 4-wire (grounded), for single-phase split-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 P identifies it as a male plug; it pairs only with the matching NEMA L14-30R.
The 30 A 125/250 V NEMA L14-30P is typically used for generators, temporary power distribution and transfer switches providing both 125 V and 250 V from one locking connector. Selecting the correct 30 A 125/250 V locking connector ensures the contacts and cable can carry the load without overheating and that the single-phase split-phase supply is connected with the proper grounding and polarity.
The NEMA L14-30P is the locking male plug, typically fitted on the end of a power cord or equipment inlet lead, and it only mates with a matching NEMA L14-30R female receptacle (socket-outlet or cord connector). It carries 30 A at 125/250 V in a 3-pole, 4-wire (grounded) configuration, so the outlet, wiring and overcurrent protection must all be rated for at least 30 A.
No. NEMA connectors are keyed by voltage, current, phase and grounding, so the NEMA L14-30P mates only within its own 30 A 125/250 V family. The L14 provides two hots, neutral and ground for 125/250 V; it is not a three-phase connector and cannot mate with L15/L16 three-phase locking types. 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 L14-30P 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.
