3M 7010396550 Twist-on Wire Connector Yellow 3 Awg 500pk

Product Description

The 3M 7010396550 is a standard twist-on wire connector rated for 600 volts and designed for fire-resistant electrical connections in residential and commercial wiring applications. Color-coded yellow for quick identification in the field, this connector handles wire sizes down to 3 AWG and maintains a maximum operating temperature of 221 degrees F. It is installed by licensed electricians and qualified electrical trades during panel work, junction box terminations, and general branch-circuit wiring tasks. Each package contains 500 connectors, making it a practical choice for high-volume jobs or stocking service vehicles and shop inventory.

This connector is suited for standard branch-circuit and fixture wiring where a reliable, code-compliant twist-on termination is required. The fire-resistant construction adds a layer of safety in enclosed boxes and panels where heat buildup is a concern. The yellow color designation allows fast sorting by wire gauge range on the job, reducing errors during high-volume termination work. Suitable for use in residential, light commercial, and industrial electrical installations where UL-listed components are specified.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. Always de-energize and lock out the circuit at the panel before making or disturbing any wire terminations. Strip conductors to the manufacturer-recommended length, insert into the connector, and twist clockwise until the connector is firmly seated with no bare copper exposed. Do not over-tighten or force connectors onto wire gauges outside the rated range.
