Thomas Betts 333KP Twist-on Wire Connector 600V Yellow 500pk

Product Description

The THOMAS BETTS 333KP is a standard twist-on wire connector rated for 600 volts, designed for splicing and terminating copper conductors in residential and commercial electrical work. The yellow color coding helps technicians quickly identify the connector during installation and inspection. Built with corrosion-resistant materials, the 333KP holds up in environments where moisture and oxidation are concerns. This connector is a staple item for licensed electricians and apprentices working on branch circuit wiring, fixture connections, and junction box splices. It is sold in a 500-piece package, making it suitable for stocking service vans, job site boxes, or supply rooms.

The 333KP is used across a wide range of electrical applications including residential rough-in wiring, commercial tenant improvements, light fixture installations, and device connections at outlet and switch boxes. The standard twist-on style suits general-purpose conductor splicing in dry, damp, and corrosion-prone locations. Electricians on large projects benefit from the 500-count packaging to minimize restocking interruptions. The connector is appropriate for use in junction boxes, outlet boxes, and panel wiring where NEC-compliant splicing methods are required.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). Always de-energize the circuit at the breaker and verify voltage is absent with a meter before making any wire connections. Strip conductors to the appropriate length, hold wires parallel, and twist the connector clockwise until snug with no bare copper exposed. Do not over-torque or use pliers on the connector body, as this may compromise the connection.
