Burndy Copper Alloy Mechanical Grounding Connector for Water Pipe

The Burndy Copper Alloy Mechanical Grounding Connector is engineered to bond copper conductors directly to metallic water pipe or ground rod, creating a dependable grounding electrode connection for electrical systems. Machined from copper alloy for long-term conductivity and corrosion resistance, this family of connectors covers a wide field range: clamp sizes span 1-1/4" - 2" pipe with a 4 AWG to 4/0 AWG conductor range, and 3/8" clamp stud versions accommodate 4 AWG to 2/0 AWG conductors. This gives electricians a straightforward, single-conductor way to establish a code-compliant bond between grounding conductors and water piping systems in both new installations and service upgrades.

Key Features

  • Wide Conductor Range: Depending on clamp size selected, accommodates 4 AWG up to 4/0 AWG copper conductors, covering both solid and stranded wire for flexible grounding applications.
  • Pipe & Stud Compatibility: Available sized to fit 1-1/4" to 2" water pipe, or with a 3/8" clamping stud for cable-to-ground-rod or tube connections, allowing direct connection to common metallic plumbing or grounding electrodes.
  • Durable Copper Alloy Construction: The copper alloy body resists corrosion and maintains reliable electrical conductivity over the life of the installation.
  • Secure Clamping Design: Provides a solid mechanical clamp that keeps the conductor firmly seated against the pipe or rod surface.
  • Single-Conductor Design: Purpose-built as a cable-to-ground-rod, pipe, or tube connector for bonding one grounding conductor at a time.
  • Mechanical Set-Type Connection: Installs with common hand tools, without the need for exothermic welding equipment, for fast field terminations.

Technical Specifications

  • Product Material: Copper Alloy
  • Conductor - Copper Tube Std Size Range: 1 1/4-2
  • Conductor - Copper Solid Size Range: 4 AWG - 4/0 AWG
  • Conductor - Copper Str Size Range: 4 AWG - 4/0 AWG
  • Alternate Clamp Configuration: 3/8" stud, 4 AWG - 2/0 AWG

Typical Applications

  • Grounding Electrode Connections to Metallic Water Pipe
  • Commercial and Industrial Grounding and Bonding Systems
  • Residential Service Ground Connections
  • Renovation and New Construction Grounding Upgrades
  • Cable-to-Ground Rod, Pipe, or Tube Bonding

Why Burndy?

Burndy GAR6426 – Frequently Asked Questions

1) Can I use this Burndy connector to land a 4/0 service grounding conductor on the incoming water main?
Yes, with the 1-1/4 inch to 2 inch pipe clamp (GAR3903). Its conductor range tops out at 4/0 AWG copper, solid or stranded, which is the largest size it will accept. Note it is a single-conductor connector, so one grounding conductor per clamp. The 3/8 inch stud version only goes to 2/0 AWG and will not take 4/0.
2) Do I need special tools or an exothermic weld kit to install a Burndy mechanical grounding connector?
No. It is a mechanical set-screw connection, tightened with common hand tools. No exothermic welding equipment, no crimp dies, no compression tool. That makes it practical for service upgrades and retrofit bonding where you cannot bring welding gear into an occupied building.
3) Will this Burndy clamp accept stranded copper as well as solid grounding wire?
Both. The pipe clamp is rated 4 AWG to 4/0 AWG for solid copper and the same 4 AWG to 4/0 AWG for stranded copper, so a stranded 2/0 or a solid 4 AWG both seat in the same connector. Copper conductor only, as the connector is built for copper-to-copper bonding.
4) Is a copper alloy grounding clamp suitable for a damp basement or a buried water pipe connection?
The body is machined copper alloy, chosen for corrosion resistance and stable conductivity over the life of the install, which suits the damp conditions around a water service entrance. It is also the right material pairing for copper pipe and copper conductor, avoiding the dissimilar-metal issue you get mixing copper wire with a plated steel clamp.
