Thomas Betts 739P Wing Twist-on Wire Connector 3 Awg 50 Pack

Product Description

The THOMAS BETTS 739P is a wing-style twist-on wire connector rated for use with conductors down to 3 AWG minimum wire size. The blue color coding identifies its wire range at a glance, and the corrosion-resistant construction protects the connection in environments where moisture or chemical exposure is a concern. Electricians and maintenance technicians use this connector to join multiple conductors quickly without tools, relying on the winged skirt for improved grip and torque during installation. Each package contains 50 connectors, making it practical for panel work, junction box terminations, and general branch-circuit wiring.

The 739P suits residential and light commercial electrical work where branch-circuit splices and terminations are performed inside junction boxes, outlet boxes, and electrical panels. Its wing design is well-suited for field conditions where technicians need to complete connections efficiently. The corrosion-resistant rating makes it appropriate for locations with elevated humidity or exposure to mild chemical environments, such as mechanical rooms, garages, and outdoor-rated enclosures.

Installation Notes

Installation is performed by licensed electricians or qualified maintenance technicians in accordance with the National Electrical Code (NEC). De-energize and lock out the circuit at the breaker before making or breaking any conductor connections. Strip conductors to the appropriate length, hold them parallel, and twist the connector clockwise until firmly seated with no exposed bare copper visible below the connector skirt. Do not use pliers or power tools to drive the connector onto conductors.
