Ideal WT4-B Twist-on Wire Connector Yellow 600V 500 Pack

Product Description

The IDEAL WT4-B is a standard twist-on wire connector designed for making secure, reliable electrical connections in residential, commercial, and light industrial wiring applications. Rated at 600 volts with a maximum operating temperature of 221 degrees F, this connector suits a wide range of branch circuit and fixture wiring tasks. The yellow, flame-retardant shell provides visual color-coding for quick identification and meets stringent safety standards including UL Listed 486C, UL Listed 774A, and CSA certification. This package contains 500 connectors, making it a practical stocking unit for electricians and electrical contractors who install connectors in volume.

The WT4-B is suited for use in residential rough-in wiring, commercial tenant improvements, and panel and junction box work where twist-on connectors are standard practice. The 2 AWG minimum compatible wire size makes it appropriate for typical branch circuit conductors. Electricians running high volumes of connections on job sites will find the 500-count package practical for reducing restocking interruptions. The flame-retardant housing adds a layer of passive protection inside junction boxes, outlet boxes, and enclosures.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize the circuit and verify absence of voltage with a meter before making or breaking connections. Strip conductors to the appropriate length, insert into the connector, and twist clockwise until the connection is firm with no bare conductor exposed below the connector shell. Do not overtighten or use pliers on the connector body, as this can crack the housing.
