Detail

3M type wire connectors includes a variety of butt splices and inline tap splices.The IDC butt splices in the
Series employ a specially designed wire insulation displacement contact to make a reliable electrical
connection to each wire. A "live-spring" joint is made by driving the wire down into the "U" contact connector.
This simple process displaces the insulation and grasps all conductors with a firm, resilient pressure, all in
one motion. These connectors include a factory installed sealant to protect against corrosion and seal out
moisture.

The Series in-line tap wire splices are real time savers. They enable the user to tap into another wire without
interrupting service. A U-shaped element inside each connector displaces insulation material and makes
contact with the copper conductor. These wire splices also include factory-installed sealant to protect against
corrosion and seal out moisture. Tap connectors are fast to install, easy to work with and available in a wide
range of common wire gauges.

Tap connectors allow direct tapping into existing solid copper conductors without interrupting service. The
pre-crimp feature helps hold the wires in place until the connector is crimped and the splice is complete.
