1. Product Overview
The Crouse-Hinds 936 Plastic Insulated Bushing is designed for use with rigid conduit systems. Its primary function is to protect electrical wires from the sharp edges of conduit ends and to provide an insulated barrier, preventing damage to wire insulation during installation and operation. This bushing is suitable for various electrical applications where conduit termination requires insulation and protection.

3. Installation / Setup
Follow these general steps for installing the Crouse-Hinds 936 Plastic Insulated Bushing:
- Safety First: Ensure all power to the electrical circuit is disconnected at the main breaker or fuse box before beginning any installation. Verify with a voltage tester.
- Prepare Conduit: Ensure the end of the 2-inch rigid conduit is clean and free of burrs or sharp edges that could damage the bushing or wires.
- Thread Bushing: Screw the plastic insulated bushing onto the threaded end of the conduit. Turn clockwise until it is hand-tight.
- Secure Connection: If applicable, use a conduit wrench to gently tighten the bushing an additional quarter to half turn to ensure a secure fit. Do not overtighten, as this can damage the plastic threads.
- Wire Pulling: Once the bushing is securely in place, wires can be safely pulled through the conduit. The smooth, insulated surface of the bushing will protect the wire insulation from abrasion.
Note: Always consult local electrical codes and standards for specific installation requirements. If you are unsure about any part of the installation process, consult a qualified electrician.
4. Function and Usage
The Crouse-Hinds 936 bushing serves two critical functions in an electrical conduit system:
- Wire Protection: It provides a smooth, rounded surface at the end of the conduit, preventing the sharp edges of the conduit from cutting or abrading the insulation of electrical wires as they are pulled through or as the system vibrates.
- Insulation: Made from plastic, the bushing offers an additional layer of insulation between the metal conduit and the electrical conductors, enhancing safety and preventing potential short circuits.
This bushing is a passive component that continuously performs its protective and insulating role once installed correctly within the conduit system.
5. Maintenance
The Crouse-Hinds 936 Plastic Insulated Bushing requires minimal maintenance. Periodic inspection is recommended, especially during any routine electrical system checks or modifications.
- Visual Inspection: Check for any signs of physical damage, cracks, or discoloration that might indicate degradation of the plastic material.
- Secureness: Ensure the bushing remains tightly threaded onto the conduit. If it has loosened, gently retighten it.
- Cleanliness: Keep the area around the bushing free from excessive dust, dirt, or moisture, which can accumulate over time.
If any damage is observed, the bushing should be replaced immediately to maintain the integrity and safety of the electrical system.
6. Troubleshooting
Issues related to conduit bushings are typically straightforward:
- Bushing is Loose: If the bushing becomes loose, it may not adequately protect the wires. Disconnect power, then gently retighten the bushing onto the conduit. Avoid overtightening.
- Bushing is Damaged (Cracked/Broken): A damaged bushing compromises wire protection and insulation. Disconnect power, carefully remove the damaged bushing, and replace it with a new Crouse-Hinds 936 bushing.
- Difficulty Pulling Wires: If wires are difficult to pull through the conduit even with the bushing installed, ensure the conduit run is clear and that the bushing is not obstructed. The bushing itself should provide a smooth path.
For any persistent or complex electrical issues, always consult a qualified electrician.
