3M 7010318552 Twist-on Wire Connector Yellow 600V 100-pack

Product Description

The 3M 7010318552 is a standard twist-on wire connector rated for 600 volts and a maximum operating temperature of 221 degrees F. The yellow, fire-resistant shell identifies the connector's wire-range category and meets CSA, UL Listed, and RoHS 2011/65/EU requirements. Electricians use twist-on connectors to join and insulate multiple conductors in residential, commercial, and light industrial wiring applications. The snap-on design creates a secure mechanical and electrical connection without additional tools. This SKU is sold in a 100-piece pack, making it well suited for high-volume rough-in work or service truck stocking.

This connector is rated for use with a minimum compatible wire size of 3 AWG and is appropriate for branch-circuit wiring in junction boxes, outlet boxes, and splice points throughout residential and commercial electrical systems. The fire-resistant housing adds a layer of safety at splices subject to elevated ambient temperatures. Electricians working under NEC requirements will find this connector meets common splice insulation and conductor-bundling standards. The 100-piece package quantity suits production wiring crews and service contractors who turn over high connector volumes daily.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit at the breaker panel and verify absence of voltage with a tested meter before making any splice. Strip conductors to the length recommended for the connector size, insert all conductors simultaneously, and rotate the connector clockwise until firm resistance is felt. Do not over-torque or use pliers to tighten twist-on connectors, as this can damage the internal spring and compromise the connection.
