3M 7100166939 Idc Run Tap Quick Splice Connector 22-16 Awg

Product Description

The 3M 7100166939 is a blue insulation displacement connector (IDC) designed for making run and tap splices on 22 to 16 AWG wire without stripping insulation. The connector uses an IDC termination method, meaning the internal metal contact pierces the wire insulation on contact to establish a reliable electrical connection. This package contains 100 connectors, making it suitable for volume wiring work on residential and light commercial projects. Licensed electricians, HVAC technicians, and low-voltage installers commonly use these connectors when adding branch connections to existing wire runs.

This connector is used wherever a technician needs to tap into an existing wire run or splice two conductors together quickly. Common applications include thermostat wiring, low-voltage control circuits, alarm systems, and lighting control runs using 22 to 16 AWG stranded or solid wire. The blue color coding indicates compatibility with the 22 to 16 AWG wire range, helping technicians select the correct connector size on the job without referencing documentation each time.

Key Features

• IDC termination requires no wire stripping, reducing installation time
• Accepts 22 to 16 AWG wire for both run and tap positions
• Blue color coding identifies the compatible wire gauge range at a glance
• Rated for a maximum operating temperature of 221 degrees F
• UL Listed and CSA Certified for use in code-compliant installations
• RoHS 2011/65/EU compliant; suitable for use in environmentally regulated applications
• Packaged in quantities of 100 for ongoing service and installation work

Compatibility

Designed as an IDC run-tap splice connector for 22 to 16 AWG solid or stranded copper wire used in low-voltage control, thermostat, and signal wiring applications.

Installation Notes

Installation is performed by placing the existing run wire and the tap wire into their respective channels and pressing the connector closed with lineman pliers or an approved IDC tool until the cap locks. Always de-energize the circuit before making or modifying any wire connections. Follow applicable NEC guidelines for connector use in the environment and enclosure type where the splice will be located. Do not exceed the rated wire gauge range, as an improper wire size will result in an unreliable or failed IDC connection.
