Bryant 71430NC Locking Connector L14-30R

This Bryant 71430NC is a straight locking connector rated 30 A at 125/250 V AC three phase. It uses a NEMA L14-30R configuration with three poles and four wires. The industrial grade housing is nylon in black and white with an IP20 rating. Screw terminals accept standard wiring for grounded, polarized connections.

Suits three-phase 30 A industrial circuits.

Electricians wiring 30 A three phase equipment will find the correct NEMA L14-30R layout here. The chemical and impact resistant nylon housing suits industrial environments. Buyers needing a shrouded body, a protective cap, or a different pole count should look at other connector types. This unit has no cap or cover included.

NEMA L14-30R three pole four wire configuration

The decisive specification is the NEMA L14-30R receptacle configuration with three poles and four wires. It defines the voltage split of 125/250 V AC across three phase conductors plus ground. Only circuits wired to this exact NEMA standard will mate correctly and safely. Verify the mating inlet matches L14-30P before purchase.

Questions about this item

How much heat does the L14-30R connector generate when carrying 30 A continuously?

The connector is rated for 30 A at 125/250 V AC with IP20 housing; normal operation at full load produces only modest warmth thanks to its nylon housing and screw-terminal design.

What wiring must already be in place for this three-phase L14-30R to work?

You need a four-wire supply (three hot conductors plus ground) sized for 30 A with screw-terminal lugs that match the connector’s straight-entry orientation.

Will this 3-pole 30 A locking connector mate with an older L14-20 inlet on my generator?

No — the L14-30R configuration is keyed differently from the 20 A variant, so it will not engage an L14-20 inlet.
