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.

Technical Specifications

Burndy GC2929CT – Frequently Asked Questions

1) What conductor sizes does the Burndy GC2929CT cable tray ground clamp accept?
The GC2929CT takes stranded copper from 2/0 AWG up to 250 kcmil, and 4/0 AWG solid. So a 4/0 stranded ground run or a 250 kcmil tray bond both land in range. Below 2/0 stranded you are outside the rated range and should pick a smaller-range clamp.
2) Can I land two ground cables on one clamp instead of using two lugs?
Yes. The GC2929CT is built to mechanically connect one or two cables to a bar in a single clamp body, so a multi-conductor tray or bus bar termination does not need a second connector. Both cables have to fall inside the rated range: 2/0 through 250 kcmil stranded, or 4/0 solid.
3) Is this ground clamp rated for aluminum conductors or copper only?
It is Al/Cu rated, so aluminum or copper conductors are both acceptable. The connector surface is tin plated, which is what makes it suitable for aluminum terminations as well as copper without a dissimilar-metal problem at the contact point.
4) What size stud is on the Burndy GC2929CT, and what does it bolt to?
A 3/8 inch stud. That mounts the clamp to cable tray rails and to grounding or bus bar assemblies, so your bar or tray needs a 3/8 inch hole or clearance to receive it. Mounting hardware is galvanized steel.
5) Will a cast copper alloy ground clamp hold up in a damp or outdoor industrial area?
The body is cast copper alloy, the hardware is galvanized steel, and the connector surface is tin plated, which is the combination Burndy specifies for corrosion resistance and long-term torque retention in grounding and bonding work. It is used on tray, bus bar and grounding grid installs in commercial and industrial systems.
6) Is a cable tray ground clamp the right part for bonding tray sections, or do I need a bonding jumper kit?
A clamp like the GC2929CT is the termination point: it lands the grounding conductor on the tray rail or on a ground bar. The conductor between sections is a separate item you supply. If your job is simply carrying a 2/0 to 250 kcmil ground run onto tray, bus bar, panelboard or switchgear steel, this clamp is the connector for it.
7) What is the exact part number to order this Burndy tray clamp by?
Order it as Burndy GC2929CT. Burndy also catalogs it under the GC-CT product family designation, but GC2929CT is the orderable manufacturer part number.
8) Is there a spec sheet for the GC2929CT I can attach to a submittal?
Yes, Burndy publishes a spec sheet for the GC2929CT at https://hubbellcdn.com/specsheet/BRDY-GC2929CT-SPEC-EN.pdf. That is the document to drop into a grounding submittal package alongside the conductor range and 3/8 inch stud size.
