Overview

The ABB GTC24 is a two-piece copper tower ground clamp designed for secure grounding of stranded copper conductors ranging from 2/0 AWG to 250 kcmil. Constructed from high-strength, corrosion-resistant copper alloy, the GTC24 ensures low-resistance electrical connections critical for safety and system performance in industrial and utility applications. The two-piece design accommodates parallel conductors, providing flexibility in grounding configurations while maintaining mechanical strength. The clamp features a square-shank bolt to prevent rotation during tightening, enabling installation with a single wrench. With a conductor range of 250 kcmil (max) to 2/0 Str. (min), the GTC24 is ideal for grounding substations on tower footings. Its compact footprint and durable construction make it suitable for both indoor and outdoor environments where reliable grounding is essential. The clamp’s design allows for easy installation with common tools, reducing downtime during maintenance or system upgrades.
  • Two-piece copper alloy clamp for stranded copper conductors (2/0 Str. to 250 kcmil)
  • Square-shank bolt prevents rotation, enabling single-wrench installation
  • High-strength, corrosion-resistant construction for outdoor/indoor use
  • Compact design ideal for grounding substations on tower footings
