Burndy GC-A Series Mechanical Grounding Connector, Aluminum, Al/Cu Rated

The Burndy GC-A Series Mechanical Grounding Connector family links a grounding cable directly to a metal water pipe or grounding rod, providing a dependable bonding point for service grounding systems. This family is available across 8 models — GAR1429, GAR3903BU, GAR3904, GAR3905, GAR6429, GC15A, GC18A, and GC22A — covering a range of pipe and conductor accommodations to fit different job requirements. Built from aluminum and Al/Cu dual rated, connectors in this series accept conductors from #6 AWG up to 250 kcmil, with a copper solid conductor range of 6 AWG-4/0 AWG depending on the model selected. The mechanical clamp design delivers a secure, low-resistance bond between the grounding electrode conductor and the pipe, making the GC-A Series a practical choice for electrical professionals who need a code-compliant grounding connection without special crimping tools.

Key Features

Burndy GC15A – Frequently Asked Questions

1) Can I use a Burndy GC-A grounding connector with aluminum conductor, or is it copper only?
The GC-A Series is Al/Cu dual rated, so it takes both aluminum and copper conductors. That is the reason a lot of electricians standardize on this family instead of stocking separate copper-only clamps. Solid copper range is 6 AWG to 4/0 AWG, and stranded copper runs 6 AWG up to 250 kcmil.
2) Will a Burndy GC-A clamp take my 4/0 grounding electrode conductor?
Yes on 4/0, both solid and stranded. Solid copper is accommodated from 6 AWG through 4/0 AWG; stranded copper goes further, 6 AWG through 250 kcmil. Which specific model you need depends on the pipe or rod diameter you are clamping to, since the eight models in the family cover different pipe accommodations.
3) Do I need a crimping tool to install a Burndy GC-A grounding connector?
No. Termination is mechanical, a clamp body tightened onto the pipe or rod with the conductor set in the lug. No hydraulic crimper, no dies, no compression tool. That is the practical difference between the GC-A mechanical line and a compression grounding connector, and it is why it suits service work and renovations where you are making one or two connections.
4) Which Burndy GC-A model do I order for a water pipe ground?
Eight models are offered: GAR1429, GAR3903BU, GAR3904, GAR3905, GAR6429, GC15A, GC18A and GC22A. They differ in the pipe and conductor accommodation, so pick by the outside diameter of the pipe or rod you are bonding to and the size of your grounding electrode conductor. All eight share the same aluminum, Al/Cu dual-rated construction.
5) Is an aluminum grounding clamp acceptable on a copper water pipe?
The GC-A body is aluminum and the connector is dual rated for aluminum and copper conductors. Dual rating covers the conductor metals it may terminate; for the pipe itself, match the model to the pipe size and confirm the installation suits the environment. Aluminum bodies are common on service grounding for corrosion resistance and lower cost than bronze, and a bronze or copper-alloy clamp is the alternative where a direct-burial copper-to-copper connection is specified.
6) Can I use a Burndy GC-A connector on a driven ground rod as well as pipe?
Yes. The GC-A mechanical connector links a grounding cable to a metal water pipe or to a grounding rod, so it works for both the water-pipe electrode and a driven rod, provided the model you choose accommodates that diameter.
7) What is the smallest conductor a Burndy GC-A clamp will hold?
6 AWG is the bottom of the range, in both solid and stranded copper. If you are landing a 8 AWG or smaller bonding jumper, this family is oversized for it and you want a smaller-range clamp instead.
8) Where can I get the dimensional spec sheet for the Burndy GC18A?
Burndy publishes a spec sheet for the GC18A through Hubbell at https://hubbellcdn.com/specsheet/BRDY-GC18A-SPEC-EN.pdf. That is the document to check for the pipe size accommodation and clamp dimensions before you order a specific model out of the eight in the GC-A family.
