Bi-Metal Connector

Used in Aluminum applications.


Product Description

Used in Aluminum applications. Part number M3. This is required to transition from aluminum cable to 5 feet or more of Copper cable before connecting to your ground rod or ground plate. Connection is made at least 12 inches above grade. Use one for each grounding location. All tops of ground rods or plates must be buried at least 2 feet below grade. You CAN’T ground with just aluminum.

Bolt tension connecters are the best.  You tighten it well enough and you never have to worry if it will come loose, especially in concealed systems.  It’s well worth the extra money.  It’s all we use on our installations.
