Bryant 480V AC Locking Wire Cap Connector

This Bryant locking wire cap connector is rated for 480V AC and 20A three-phase power. It uses a NEMA L16-20R configuration with three poles and four wires for grounded industrial connections. The straight-orientation housing is moulded from chemical- and impact-resistant nylon in black and white. Screw terminals provide a secure wire connection without a shroud or cap.

Thermals Noise and Power Draw

As a passive electrical connector the device generates no heat and produces no audible noise during normal operation. Power draw is determined entirely by the connected load up to the 20A rating. The nylon housing resists chemical exposure and mechanical impact in industrial environments. No active cooling or power supply is required for the connector itself.

NEMA L16-20R Three-Pole Four-Wire Configuration

The single specification that decides suitability is the NEMA L16-20R receptacle configuration with three poles and four wires at 480V AC. This matches only circuits wired for 20A three-phase grounded service with a locking straight blade. Installations requiring a different NEMA rating, pole count, voltage or phase arrangement cannot use this connector.

Questions about this item

How do I wire the screw terminals on the 71620NC and which step do installers often miss?

Strip each conductor, insert it into the correct screw terminal — black and white for hot, green for ground, and the remaining wire for neutral — then tighten every screw to the rated torque; the step most often missed is confirming the neutral is seated in the designated terminal before closing the housing.

What maintenance or replacement will the 71620NC connector need over time?

Inspect the nylon housing and screw terminals periodically for discoloration, cracked insulation or loose screws caused by vibration; replace the entire connector if any terminal shows pitting, the housing is deformed, or the IP20 seal no longer closes cleanly.

At what point does the 20 A, 480 V AC rating become the limiting factor during sustained use?

The connector is rated for a continuous 20 A at 480 V AC; the first limit reached under sustained load is the 20 A current ceiling — exceeding it will overheat the screw terminals and nylon housing before the voltage or horsepower ratings are stressed.
