Burndy GC2929CT Cast Copper Alloy Cable Tray Ground Clamp, 3/8" Stud

Burndy GC2929CT Cast Copper Alloy Cable Tray Ground Clamp, 3/8" Stud

The Burndy GC2929CT is a cast copper alloy mechanical grounding cable tray clamp engineered to connect one or two cables to a grounding bar in a single, compact clamp body. Rated for 2/0 Str-250 kcmil Al/Cu conductors, it features a 3/8" stud, galvanized steel hardware, and a tin-plated connector surface that together deliver a dependable, corrosion-resistant grounding connection for cable tray, bus bar, and grounding grid installations across commercial and industrial electrical systems.

Key Features

• Stud Size: 3/8" stud accommodates secure mechanical mounting to cable tray rails and grounding bar assemblies.
• Durable Construction: Cast copper alloy body resists corrosion and provides long-term mechanical strength in demanding grounding and bonding applications.
• Conductor Range: Al/Cu rated for 2/0 Str-250 kcmil stranded conductors, with a 4/0 AWG solid conductor range also supported for flexible field use.
• One-to-Two Cable Connection: Mechanically connects one or two grounding cables to a bar in a single clamp body, simplifying multi-conductor grounding terminations.
• Galvanized Steel Hardware: Corrosion-resistant galvanized steel hardware supports reliable long-term torque retention on the clamp assembly.
• Tin-Plated Connector: Tin-plated connector surface improves conductivity and reduces oxidation at the termination point over the life of the installation.
