Product Description

The THOMAS BETTS 329-BP is a standard twist-on wire connector rated for 300 volts and built with corrosion-resistant construction. Twist-on connectors are used to join and insulate the ends of copper conductors in branch-circuit wiring applications. The 329-BP ships in a pack quantity of 1000 units, making it a practical choice for electricians working on large installations or stocking a service vehicle. The gray color coding identifies the connector size range for quick sorting on the job. UL Listed and RoHS compliant, this connector meets standard electrical code requirements for residential and commercial wiring work.

Twist-on wire connectors in this style are a staple in residential, commercial, and light industrial electrical work. They are used wherever conductors must be spliced inside junction boxes, outlet boxes, panel enclosures, and fixture housings. Licensed electricians and apprentices alike use these connectors daily for device wiring, fixture installations, and general branch-circuit terminations. The 1000-piece pack quantity suits wholesale restocking, electrical contractors running multiple jobs, and supply house distribution.

Installation Notes

Twist-on wire connectors are installed by licensed electricians or qualified persons in accordance with NFPA 70 (NEC). Always de-energize the circuit at the breaker and verify with a non-contact voltage tester before making any splice. Strip conductors to the length specified by the connector manufacturer, insert conductors into the connector, and twist clockwise until firm resistance is felt. Do not use these connectors on aluminum conductors unless the connector is specifically rated for aluminum-to-copper or aluminum-only use.
