Nsi Industries 257-DC2 3 Inch Compression Connector

Product Description

The NSI INDUSTRIES 257-DC2 is a 3-inch compression connector designed for securing electrical conduit to enclosures, junction boxes, and panels. Compression connectors provide a tight mechanical connection without threading, making them a practical choice for conduit terminations in both new construction and retrofit electrical work. This fitting is sized for 3-inch conduit and is installed by licensed electricians working on commercial and industrial wiring systems where conduit integrity and secure termination are required.

This compression connector is suited for use in conduit installations where a reliable, vibration-resistant termination is needed. Typical applications include panel feeds, junction box entries, and conduit runs in commercial buildings, industrial facilities, and utility installations. The 3-inch size accommodates larger conduit runs common in high-capacity feeder circuits.

Key Features

• 3-inch conduit size for large feeder and distribution runs
• Compression-style connection provides secure, vibration-resistant termination
• No threading required for installation
• Suited for conduit-to-enclosure and conduit-to-panel terminations

Compatibility

Designed as an OEM-style replacement and standard compression connector fitting for 3-inch electrical conduit applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize all circuits and verify the absence of voltage before working inside any panel or enclosure. Ensure the conduit is cut cleanly and deburred before seating the compression connector to achieve a proper mechanical fit.
