Burndy GC18A Mechanical Grounding Connector

Burndy GC18A Mechanical Grounding Connector, Cable to Water Pipe, Aluminum, Al/Cu Rated

The Burndy GC18A Mechanical Grounding Connector links a grounding cable directly to a metal water pipe, accepting conductors from #6 AWG up to 250 kcmil and fitting pipe sizes from 1-1/4" to 2". Built from aluminum and Al/Cu rated, this connector is engineered for reliable, code-compliant grounding connections in both aluminum and copper conductor applications. The mechanical clamp design, part of Burndy's GC-A series, delivers a secure, low-resistance bond between the grounding electrode conductor and the water pipe, making it a practical choice for electrical professionals who need a dependable bonding point for service grounding systems. Its dual-rated construction means a single connector can be specified for either aluminum or copper cable, simplifying material selection on the job and reducing the number of parts an installer needs to stock.
