Burndy GAR3906 Copper Mechanical Grounding Connector for 6" Water Pipe

The Burndy GAR3906 is a mechanical grounding connector engineered to join a conductor to a 6" water pipe, providing a secure, code-compliant grounding electrode connection for electrical service and equipment grounding systems. Built with a Copper Alloy connector body and galvanized steel hardware, this single-conductor (GAR-series) connector accommodates a wide 4 AWG - 4/0 AWG conductor range and terminates with a 3/8" stud. It is designed for the demanding, corrosion-resistant performance required in commercial and residential grounding installations where a dependable conductor-to-water-pipe connection is essential.

Key Features

  • Trade Size: Sized for a 6" water pipe with a 3/8" connecting stud for a secure, properly fitted mechanical connection.
  • Conductor Range: Accepts 4 AWG - 4/0 AWG copper conductors, covering both solid and stranded conductor configurations.
  • Durable Construction: Copper Alloy connector body resists corrosion for long-term grounding reliability in the field.
  • Galvanized Steel Hardware: Connection hardware is galvanized steel, adding corrosion resistance to the overall assembly.
  • Single-Conductor Design: Part of Burndy's GAR series of cable-to-ground-rod/pipe/tube connectors, purpose-built for conductor-to-water-pipe grounding applications.
  • Mechanical Connection: Mechanical, set-screw-style termination allows straightforward field installation without specialized crimping tools.

Burndy GAR3906 – Frequently Asked Questions

1) Will a Burndy GAR ground connector take my 2/0 grounding electrode conductor?
Yes. The Burndy GAR series mechanical grounding connector accepts copper conductors from 4 AWG through 4/0 AWG, and that range covers both solid and stranded conductors. So 2/0 sits comfortably in the middle of the range, as does a typical 4 AWG service ground or a full 4/0.
2) What pipe size does the Burndy GAR3906 water pipe ground clamp fit?
The GAR3906 is sized for 6 inch water pipe and terminates the conductor on a 3/8 inch stud. If your grounding electrode is a smaller water pipe, order the GAR3904BU standard pipe size version instead of the 6 inch one.
3) What is the difference between the GAR3904BU and the GAR3906?
Pipe size is the only ordering choice. GAR3904BU is the standard pipe size version and GAR3906 is built for 6 inch water pipe. Both are copper alloy mechanical connectors taking 4 AWG through 4/0 AWG copper. Measure the actual pipe at the point you intend to clamp before picking one.
4) Do I need a crimping tool to install this Burndy grounding connector?
No. This is a mechanical, set screw style termination, so it goes on with hand tools in the field. No hydraulic crimper, die set, or exothermic mold is needed, which is why electricians reach for it on service change and renovation work where a compression or welded connection is impractical.
5) Is a copper alloy water pipe ground clamp okay for a direct-buried or damp basement location?
The connector body is copper alloy and the connection hardware is galvanized steel, both chosen for corrosion resistance on grounding electrode connections. That construction is what makes it workable at a basement water service entrance where humidity and condensation are constant. Copper alloy on a copper water pipe also avoids the dissimilar metal problem you would get with a steel clamp.
6) Can I land two grounding conductors in one of these Burndy GAR connectors?
No. The GAR series is a single-conductor connector, one conductor to one pipe. If you need to bond a second conductor, such as running a bonding jumper around a water meter as well as the main grounding electrode conductor, use a second connector on the pipe rather than doubling wires into one.
7) Can I use this on a ground rod instead of a water pipe?
The GAR family is Burndy's cable to ground rod, pipe and tube connector line, and this particular connector is sized and specified for conductor to water pipe. For a driven rod, order a clamp sized to the rod diameter rather than a 6 inch pipe connector, since the clamping range will not close down on a 1/2 or 5/8 inch rod.
8) Is this the right connector for bonding a metallic water service at the panel?
That is exactly the job it is built for: tying the grounding electrode conductor from a service entrance or panelboard to a metallic water pipe electrode. It handles the usual conductor sizes for that run, 4 AWG up to 4/0 AWG copper, in both new construction and retrofit service upgrades.
