Ideal WT4-1 Twist-on Wire Connector Yellow 600V 100 Pack

Product Description

The IDEAL WT4-1 is a standard twist-on wire connector rated for 600 volts and a maximum operating temperature of 221 degrees F. It features a flame-retardant insulating shell in a yellow color coding that identifies it for use with 2 AWG minimum compatible wire sizes. This connector is designed for making secure, insulated wire terminations in residential and commercial electrical installations. Electricians use it to join conductors in junction boxes, panels, and fixture connections wherever a reliable, code-compliant twist-on splice is required. Each package contains 100 connectors.

The WT4-1 suits a wide range of branch-circuit and fixture wiring applications where conductors must be joined without soldering or additional tape wrapping. The yellow shell provides quick visual identification of wire gauge range on the job. It is appropriate for use in indoor electrical boxes, conduit terminations, and device wiring across residential, light commercial, and industrial settings. Licensed electricians and qualified electrical contractors are the primary installers of this component.

Compatibility

Designed as a standard OEM-style twist-on wire connector for use in residential and commercial electrical wiring applications requiring a 600-volt-rated, flame-retardant splice connector.

Installation Notes

De-energize all circuits at the breaker panel and verify zero voltage with a meter before making any wire connections. The WT4-1 is installed by a licensed electrician in accordance with the National Electrical Code (NEC). Strip conductors to the appropriate length, align wire ends, and twist the connector clockwise until snug with no bare conductor exposed. Do not overtighten to the point of cracking the shell or distorting the conductor ends.
