Technical Specifications

This insulating bushing features a 1-inch trade size with threaded connection for rigid and IMC conduit systems. The high-grade plastic construction provides 105°C temperature rating while maintaining excellent insulating properties. Compact dimensions of 2.12" length, 1.4" width, and 1.06" height allow installation in space-constrained applications. The lightweight 0.02 lb design reduces installation fatigue while providing professional-grade performance. NEC/CEC compliant construction ensures code compliance for ordinary/non-hazardous locations.

Installation Process

1. Verify conduit end is properly reamed and deburred to prevent wire damage
2. Thread the insulating bushing onto the conduit end using appropriate tools
3. Tighten securely to ensure proper mechanical and electrical connection
4. Verify the bushing is properly seated and aligned with the enclosure opening
5. Install conductors through the protected opening, taking advantage of the smooth interior
6. Complete terminations according to NEC/CEC requirements and manufacturer specifications

Applications

Perfect for:

• Commercial Buildings - Office complexes, retail centers, and healthcare facilities
• Industrial Facilities - Manufacturing plants, processing centers, and distribution warehouses
• Electrical Panel Connections - Main panels, sub-panels, and distribution equipment
• Motor Control Centers - MCC connections and industrial control applications
• Switchgear Installations - High-voltage switching and distribution equipment
• Equipment Connections - Machinery, HVAC systems, and process equipment
• Municipal Infrastructure - Schools, government buildings, and public facilities
• High-Temperature Applications - Areas where conductors operate at elevated temperatures

Insulating Bushing System Benefits

Insulating bushings provide critical protection that standard locknut and bushing combinations cannot match. The insulated throat design eliminates the possibility of conductor contact with the conduit system, preventing ground faults and ensuring electrical safety. This is particularly important in high-current applications where conductor heating could cause insulation degradation. The smooth interior surface also reduces installation time by allowing easier wire pulling while protecting expensive conductors from damage during installation.

Why Choose High-Temperature Plastic Construction?

The 105°C temperature rating makes this bushing ideal for applications with high-temperature conductors or elevated ambient conditions. Unlike standard plastic bushings, this professional-grade construction maintains its insulating properties and mechanical strength even under thermal stress. The plastic material also provides superior corrosion resistance compared to metal alternatives, ensuring long-term reliability in challenging environments while maintaining the lightweight, easy-to-install characteristics that electrical contractors prefer.
