Introduction
This manual provides instructions for the proper use and installation of the Arlington EMT200-50 EMT Insulating Conduit Bushing. These bushings are designed to protect electrical cables from abrasion when installed in Electrical Metallic Tubing (EMT).
Product Overview
The Arlington EMT200-50 is a 2-inch insulating bushing, supplied in a 50-pack, specifically designed for EMT conduit. Its primary function is to create a smooth, protective surface at the end of EMT, preventing damage to wires during installation and throughout their service life.
- 2-Inch size for EMT conduit.
- Supplied in a convenient 50-pack.
- Protects cables from abrasion by EMT.
- Meets 2005 NEC code requirements for 300-15C protection.
- Listed for use in environmental air handling spaces per 2005 NEC code requirements 300-22 C.
Safety Information
Always disconnect power before working on electrical systems. Wear appropriate personal protective equipment. Ensure all installations comply with local and national electrical codes, including the National Electrical Code (NEC). Improper installation can lead to electrical hazards, injury, or property damage. These bushings are intended for use with Electrical Metallic Tubing (EMT) only.
Setup and Installation
- Prepare the EMT Conduit: Ensure the end of the EMT conduit is cut cleanly and deburred to remove any sharp edges or burrs that could damage the bushing or wires.
- Select the Correct Bushing: Verify that the bushing size (2-inch) matches the diameter of your EMT conduit.
- Install the Bushing: Firmly press or thread the insulating bushing onto the end of the EMT conduit. The bushing should fit snugly and securely, providing a smooth, insulated surface.
- Route Wires: Carefully route electrical wires through the conduit, ensuring they pass smoothly over the installed bushing without snagging or abrasion.
Operation
Once installed, the Arlington EMT Insulating Conduit Bushing functions passively by providing a smooth, non-abrasive surface at the termination point of EMT conduit. This prevents the sharp edges of the conduit from cutting, scraping, or otherwise damaging the insulation of electrical wires as they are pulled through or rest within the conduit. This protection is crucial for maintaining the integrity of electrical systems and preventing short circuits or ground faults.
Maintenance
The Arlington EMT Insulating Conduit Bushing is designed for long-term, maintenance-free operation. Periodically inspect installed bushings for any signs of physical damage or degradation, especially in harsh environments. If a bushing appears damaged, replace it immediately to ensure continued wire protection.
Troubleshooting
- Bushing does not fit: Ensure the bushing size matches the EMT conduit diameter. This EMT200-50 model is for 2-inch EMT.
- Bushing is loose: Re-check the conduit end for burrs or deformities that might prevent a snug fit. Replace the bushing if it appears stretched or damaged.
- Wires are still abrading: Verify the bushing is fully seated and inspect the conduit interior for any remaining sharp edges beyond the bushing's reach. Ensure proper wire pulling techniques are used.
