Southwire 393C 1 Inch Emt Coupling Conduit Fitting

Product Description

The SOUTHWIRE 393C is a 1-inch EMT coupling used to join two sections of electrical metallic tubing (EMT) in a continuous conduit run. It provides a secure, low-profile connection that maintains raceway integrity and supports proper wire protection in both residential and commercial wiring installations. Electricians use this coupling during rough-in work when extending or connecting EMT conduit runs through walls, ceilings, and mechanical spaces. The fitting is sized for 1-inch EMT and is designed to meet standard conduit installation requirements.

This coupling is suited for use in standard dry or damp interior electrical installations where 1-inch EMT conduit is specified. It is commonly installed in commercial buildings, industrial facilities, and residential projects where metallic conduit is required by code or preferred for mechanical protection of conductors. The 393C fits into standard conduit layouts and works with the full range of 1-inch EMT fittings and connectors used in typical electrical rough-in work.

Key Features

• Sized for 1-inch EMT conduit for straightforward inline connections
• Low-profile coupling design maintains clean conduit runs
• Compatible with standard 1-inch EMT conduit systems used in commercial and residential wiring
• Supports code-compliant raceway installations per NEC requirements

Compatibility

Designed as an OEM-style replacement and standard fitting for 1-inch EMT conduit systems in commercial and residential electrical installations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits in the work area before beginning conduit work. Use appropriate conduit reamers and wrenches when assembling EMT fittings to avoid damaging conduit ends or coupling threads. Verify that the completed raceway is properly bonded and grounded as required by the governing electrical code.
