Nsi Industries 230 1/2 in Steel Set Screw Emt Connector

Product Description

The NSI INDUSTRIES 230 is a 1/2 inch steel set screw connector designed for use with electrical metallic tubing (EMT) conduit systems. It provides a secure, low-profile mechanical connection between EMT conduit and a knockout on an electrical box, panel, or enclosure. The set screw fastening method locks the conduit in place without requiring threading or compression tooling, making it a fast and reliable option for raceway installations. Licensed electricians and electrical contractors install this fitting as a standard component in branch circuit and feeder wiring systems.

This connector is suited for residential and light commercial electrical installations where EMT conduit is the raceway of choice. It is used at termination points where conduit enters junction boxes, load centers, pull boxes, and similar enclosures. The 1/2 inch trade size accommodates the most common EMT conduit diameter found in standard wiring runs.

Key Features

• Set screw fastening provides a solid mechanical connection without compression tooling
• 1/2 inch trade size fits standard EMT conduit
• Steel construction for durability in typical indoor raceway applications
• Compatible with standard knockout openings on electrical enclosures

Compatibility

Designed as an OEM-style replacement and standard-use fitting for 1/2 inch EMT conduit terminations at electrical boxes and enclosures.

Installation Notes

Installation is performed by a licensed electrician in accordance with applicable NEC requirements. De-energize the circuit and verify the enclosure is de-energized before installing or removing conduit fittings. Insert the EMT conduit into the connector body and tighten the set screw with a standard screwdriver or hex key to secure the conduit. Ensure the locknut on the enclosure side is properly tightened to maintain mechanical integrity and equipment grounding continuity.
