Burndy Pipe Ground Clamp 8In 467 750

SKU CH-4WQT-HB47N

Grounding clamp for 8 AWG to 750 kcmil copper wire on 4 in to 5 in rods, UL 467 listed for direct burial

  • TypeCommercial
  • Accommodates 8 AWG to 750 kcmil conductors for versatile grounding
  • UL 467 listed for direct burial safety compliance
  • Copper construction ensures reliable conductivity and corrosion resistance
  • Fits 4 in to 5 in ground rods and pipes securely
  • Mechanical connector design allows straightforward installation without special tools

Ground Clamp for Direct Burial

The Burndy pipe ground clamp connects a single copper grounding conductor to a ground rod or pipe in direct-burial applications. It accepts wire sizes from 8 AWG up to 750 kcmil and is UL Listed to UL467 for this use. The mechanical connector suits commercial electrical installations that require a reliable earth ground.

Thermal Performance and Power Draw

As a passive mechanical connector the clamp generates no heat and draws no power during normal operation. Its copper construction provides a stable, low-resistance path to earth without active cooling or energy consumption. Noise is not a factor because the device has no moving parts.

Installation Requirements and Space Savings

The clamp fits ground rods or pipes from 4 in to 5 in diameter and uses a 3/8 in bolt for secure attachment. It eliminates the need for exothermic welding kits or specialised crimping tools on site. The single-wire design keeps the grounding point compact while meeting direct-burial code requirements.

Questions about this item

How do I install the clamp on a 4 in to 5 in rod and which step is commonly missed?

Place the clamp around the rod or pipe, insert the copper conductor between 8 AWG and 750 kcmil, then tighten the 3/8 in bolt until the conductor is firmly secured; the step often missed is verifying full bolt torque for direct burial compliance.

What maintenance or replacement will this ground clamp need over time?

Inspect the copper body and bolt periodically for corrosion or loosening; retighten the 3/8 in bolt if it backs off, and replace the clamp if the copper shows pitting or the bolt threads are damaged.

What limit appears first when the clamp carries continuous fault current?

The 750 kcmil maximum conductor size sets the ampacity ceiling; sustained current above that rating will overheat the copper connection before any other component fails.
