  • Crouse-Hinds heritage - Backed by over 100 years of electrical innovation
  • Dimensional stability - Maintains proper fit throughout service life

Technical Specifications

This 3" insulating bushing features threaded construction for secure attachment to rigid and IMC conduit systems. The high-temperature plastic material provides 105°C continuous operation rating, making it suitable for demanding electrical applications. Measuring 4.14" in length, 2.7" in width, and 1.4" in height, this lightweight 0.1 lb bushing offers easy handling during installation while providing robust protection. The insulated throat design ensures complete electrical isolation in ordinary/non-hazardous locations, meeting NEC/CEC standards for professional electrical installations.

Installation Process

  1. Verify conduit end is properly reamed and deburred to prevent wire damage
  2. Thread the insulating bushing onto the 3" rigid or IMC conduit end
  3. Tighten securely using appropriate tools, ensuring proper seating
  4. Verify the insulated throat provides complete coverage of conduit opening
  5. Pull conductors through the smooth bushing interior
  6. Inspect installation to ensure no sharp edges contact wire insulation

Applications

Perfect for:

  • Commercial Buildings - Office complexes, retail centers, hospitals, and schools
  • Industrial Facilities - Manufacturing plants, processing facilities, and warehouses
  • Electrical Panel Connections - Main distribution panels and sub-panel feeders
  • Motor Control Centers - Large motor and equipment connections
  • Switchgear Applications - High-amperage distribution systems
  • Service Entrance Equipment - Main electrical service connections
  • Transformer Connections - Primary and secondary wiring protection
  • Heavy-Duty Circuits - Large conductor installations requiring 3" conduit

Insulating Bushing System Benefits

Insulating bushings are essential components in professional electrical installations, providing critical protection that standard locknut and bushing combinations cannot match. The insulated throat design eliminates the risk of conductor damage from sharp conduit edges while ensuring electrical isolation between the grounded conduit system and live conductors. This protection is especially important in large conduit sizes where conductor installation forces are higher and the risk of insulation damage increases significantly.

Why Choose High-Temperature Plastic Construction?

The 105°C temperature rating of this plastic insulating bushing makes it ideal for applications where elevated temperatures are present, such as near transformers, motors, or in high-ambient temperature environments. Unlike standard plastic bushings, this high-temperature design maintains its structural integrity and insulating properties even under thermal stress, ensuring long-term reliability in demanding electrical installations. The lightweight plastic construction also reduces installation fatigue while providing the same level of protection as heavier alternatives.
