Wire Tap/Connectors

Single-Sided

Entry

Dual-Sided

Entry

Inline Entry

These tap/connectors join larger wire sizes, such as power and control cable in distribution panels. Insert your main wire into a port, then insert tap wires into the other ports and tighten the set screws. The wires lock in place for a consistent and durable connection.

Single-Sided Entry—Insert all your wires from the same side. The slim profile fits better in crowded panels and boxes than dual-sided entry tap/connectors.

Dual-Sided Entry—Stagger multiple wires running from opposite directions—especially rigid wire that won't bend around the connector. For a safe flow of current, attach only one wire per port. Wires connected on both sides may overload the port, causing the connector to overheat and fail.

Inline Entry—Connect wires from opposite directions to create a straight run. Similar to butt splices.

Aluminum and Copper (For Joining Dissimilar Metals)—Aluminum and copper don't play well together, but these connectors keep them in line. They cover the wires with an antioxidant compound so the aluminum wire—and the whole connection—won't oxidize and corrode.

Underground Wire Tap/Connectors


Single-Sided Entry	Offset Entry

Plugged and sealed at every opening, these tap/connectors protect wire from groundwater and rocky soil. The trim-to-size port plugs create a tight seal where the wire enters. The other plugs have double O-rings to seal off gaps around the set screws.

Single-Sided Entry—Insert all your wires from the same side. The slim profile fits better in crowded panels and boxes than dual-sided entry tap/connectors.

Offset Entry—Attach wires running from opposite directions—especially rigid wire that won't bend around the connector. The connection points are staggered so that current flows freely instead of concentrating in one spot and causing a fault.
