Southwire ET8 3 Inch Aluminum Set Screw Emt Connector

Product Description

The SOUTHWIRE ET8 is a 3-inch aluminum set screw connector designed for use with electrical metallic tubing (EMT) conduit systems. This fitting secures EMT conduit to electrical enclosures, junction boxes, and panels using a set screw fastening method, providing a reliable mechanical connection without the need for threading. Constructed from aluminum, the ET8 offers corrosion resistance suitable for commercial and light industrial wiring applications. Licensed electricians and electrical contractors install this type of connector as a standard component in conduit rough-in work. At 7 pounds per package, it is typically sold in a quantity that suits production wiring tasks.

The ET8 connector is suited for 3-inch EMT conduit installations in commercial construction, industrial facilities, and large residential service work. It is used wherever EMT conduit terminates at an enclosure or panel and a secure, code-compliant mechanical connection is required. The set screw design allows for straightforward installation with a common hex key or nut driver, making it a practical choice for high-volume conduit work where speed and reliability are priorities.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements for conduit fittings and enclosure connections. De-energize all circuits and verify the absence of voltage before beginning work on any panel, junction box, or enclosure where this connector will be installed. Use the correct hex key or nut driver to tighten the set screw firmly against the conduit — do not overtighten to the point of deforming the conduit wall. Ensure the conduit end is cut cleanly and deburred before inserting into the connector.
