3M 7010348891 Twist-on Wire Connector 600V Orange 100pk

Product Description

The 3M 7010348891 is a standard twist-on wire connector rated for 600 volts and engineered with fire-resistant construction for use in residential and commercial electrical installations. The orange color code indicates compatibility with wire gauges down to 3 AWG, making these connectors suitable for branch circuit wiring and general conductor splicing. With a maximum operating temperature of 221 degrees F, these connectors maintain a secure, insulated termination under sustained heat loads. Each package contains 100 connectors. Licensed electricians and experienced electrical contractors are the primary installers for this product type.

These twist-on wire connectors are used wherever conductors must be joined inside junction boxes, outlet boxes, panel enclosures, and fixture housings. The orange shell provides quick visual identification of wire gauge range during rough-in and finish electrical work. Applications include residential branch circuit splices, commercial tenant improvement wiring, and light industrial control panel work. The fire-resistant shell material adds a margin of safety in enclosed spaces where heat buildup is a concern.

Installation Notes

Installation must be performed by a qualified electrician in accordance with applicable NEC requirements and local amendments. De-energize and lock out the circuit at the panel before making any wire connections. Strip conductors to the depth specified for the connector size, insert conductors together, and rotate the connector clockwise until snug with no bare copper exposed below the skirt. Do not over-torque or use power tools to drive twist-on connectors.
