Technical Specifications

This 4" trade size grounding bushing features malleable iron construction with a threadless design for rigid and IMC conduit applications. The integrated aluminum grounding lug accommodates #3/0 through 6 AWG grounding conductors, while the set screw connection method ensures reliable mechanical attachment. With a 150°C temperature rating and NEC/CEC compliance, this bushing measures 5.06" in length and depth with a 1.13" height, weighing 0.9 pounds for substantial durability in demanding electrical environments.

Installation Process

1. Verify conduit end is cut square and deburred for proper bushing fit
2. Slide the grounding bushing over the conduit end until fully seated
3. Tighten the set screw securely against the conduit to establish mechanical connection
4. Strip grounding conductor to appropriate length per manufacturer specifications
5. Insert grounding conductor into aluminum lug and tighten connection screw
6. Verify secure mechanical and electrical connections before energizing system

Applications

Perfect for:

• Commercial Electrical Systems - Office buildings, retail centers, hospitals, and educational facilities
• Industrial Installations - Manufacturing plants, processing facilities, and heavy industrial applications
• Equipment Grounding - Motor control centers, switchgear, and electrical distribution panels
• Service Entrance Applications - Main electrical service connections requiring reliable grounding
• Municipal Infrastructure - Government buildings, schools, and public facility electrical systems
• High-Temperature Environments - Applications up to 150°C where standard bushings may fail
• Large Conduit Runs - 4" rigid and IMC conduit systems in commercial and industrial settings
• Code-Critical Installations - Projects requiring strict NEC/CEC compliance for grounding systems

Grounding Bushing System Benefits

Grounding bushings provide essential electrical safety by ensuring continuous grounding paths in conduit systems. Unlike standard bushings that only provide mechanical protection, grounding bushings like the HGLS series create reliable electrical connections between the conduit system and equipment grounding conductors. This dual function eliminates the need for separate grounding components while ensuring code compliance and electrical safety in commercial and industrial installations.

Why Choose Malleable Iron Construction?

Malleable iron offers superior mechanical properties compared to standard steel or aluminum alternatives, providing exceptional impact resistance and long-term durability. The threadless design with set screw connection eliminates potential threading failures while maintaining secure conduit attachment. Combined with Eaton Crouse-Hinds' century of electrical innovation, this grounding bushing delivers the reliability and performance that electrical professionals demand for critical grounding applications in commercial and industrial electrical systems.
