Eaton 4771N 15A 277V Locking Plug

The Eaton 4771N is a NEMA L7-15 straight blade plug rated for 15 amps at 277 volts. It uses a phenolic housing and suits industrial environments where a secure locking connection is required. The device accepts conductors from #16 to #12 AWG.

Two-pole three-wire back-wiring design

This two-pole three-wire plug features back-wiring terminals that accept cable diameters from 0.33 to 0.66 inches. The auto-grip locking mechanism secures the cord without a separate clamp. It frees up wiring time by eliminating screw-terminal loops.

Phenolic body handles sustained industrial load

The phenolic construction resists heat and impact during continuous 15A service at 277V. The locking blades maintain contact pressure under vibration so the connection does not degrade over long runs. It is not suited for applications requiring higher amperage or a different voltage rating.

Questions about this item

What is the maximum current the Eaton 4771N can handle continuously?

The Eaton 4771N is rated for 15 A at 277 V, so sustained loads should not exceed 15 amps.

How much heat does the phenolic body generate during all-day operation?

Phenolic material resists heat buildup; the plug runs cool under normal 15 A loads with proper wire connections.

What wire gauges must I already have to wire this plug?

You need conductors between #16 and #12 AWG to match the plug’s back-wiring terminals.
