Technical Specifications

This 5" trade size insulating bushing features threaded installation for rigid and IMC conduit systems. The high-temperature plastic construction provides 105°C continuous operation rating, making it ideal for motor control applications and industrial equipment connections. Dimensions include 6.75" length, 4.05" width, and 2.43" height, with a lightweight 0.4 lb construction that simplifies installation. The insulated throat design ensures NEC/CEC compliance for ordinary location installations.

Installation Process

1. Verify conduit end is properly reamed and deburred to prevent damage to bushing threads
2. Thread bushing onto 5" rigid or IMC conduit end, ensuring full engagement of threads
3. Tighten bushing hand-tight plus 1/4 turn using appropriate tools to prevent over-tightening
4. Verify bushing is properly seated and throat opening is aligned with conduit interior
5. Install conductors through bushing throat, taking advantage of smooth interior surface
6. Complete electrical connections according to NEC/CEC requirements and local codes

Applications

Perfect for:

• Industrial Motor Control Centers - High-temperature rating handles motor starter and VFD applications
• Commercial Distribution Panels - Large conduit entries in office buildings, retail centers, and hospitals
• Manufacturing Facilities - Equipment connections in processing plants and production environments
• Municipal Infrastructure - Schools, government buildings, and public facility electrical systems
• Heavy-Duty Equipment Connections - Switchgear, transformers, and large electrical equipment installations
• High-Temperature Environments - Applications where standard bushings may fail due to heat exposure
• Large Feeder Installations - Main electrical feeds requiring 5" conduit protection
• Industrial Process Equipment - Chemical plants, refineries, and manufacturing equipment connections

Insulating Bushing System Benefits

Insulating bushings provide critical wire protection that standard locknut and washer combinations cannot match. The insulated throat eliminates the sharp metal edges found in basic conduit connections, preventing conductor damage during installation and service. This protection is especially important in large conduit systems where wire pulling forces are significant and conductor replacement costs are substantial.

Why Choose High-Temperature Plastic Construction?

The 105°C temperature rating of this Crouse-Hinds insulating bushing makes it ideal for motor control and industrial applications where heat buildup is a concern. Unlike standard plastic bushings that may soften or degrade in high-temperature environments, this professional-grade construction maintains its protective properties and dimensional stability. The lightweight plastic design also simplifies installation compared to metal alternatives while providing superior corrosion resistance in challenging environments.
