  • TypeCommercial
  • UL 467 listed for direct-burial grounding

Ground Clamp for 1/2 in to 1 in Pipe

This Burndy ground clamp connects a single copper conductor to water pipe or ground rod. It accepts wire sizes from 8 AWG up to 750 kcmil and is UL 467 listed for direct burial. The mechanical connector suits commercial electrical grounding work where a reliable pipe bond is required.

Thermals Noise and Power Draw

As a passive mechanical connector the clamp generates no heat and draws no power during operation. There are no moving parts or active cooling to produce audible noise. Performance depends only on the torque applied to the 3/8 in bolt and the condition of the pipe surface.

Build Quality and Mounting Implications

The copper body resists corrosion in buried or damp environments. The 3/8 in bolt clamps onto pipe diameters between 1/2 in and 1 in without additional adapters. Direct burial rating means the assembly can remain underground without separate enclosures or protective coatings.

Questions about this item

How do I install the clamp on a 1/2 in to 1 in pipe and tighten the 3/8 in bolt without stripping it?

Place the clamp around the pipe, insert the grounding wire between the jaws, then tighten the 3/8 in bolt with a wrench until the conductor is held firmly; over-torquing the bolt is the common error.

Will the copper body or the 3/8 in bolt need replacement after direct-burial service?

The copper clamp is rated for direct burial and requires no scheduled replacement; only the 3/8 in bolt might need attention if it corrodes after many years underground.

At what point does the 750 kcmil maximum conductor limit become the bottleneck during sustained fault current?

The clamp is UL467 listed for conductors up to 750 kcmil; that wire size is the first thermal and mechanical limit reached under prolonged high-current conditions.
