Water Pipe Ground Clamp · 1/2 in-1 in Pipe Range - Zinc Die-Cast - Nesco 620Z
SKU: NES-620Z
Water pipe ground clamp for bonding bare copper wire to 1/2 in to 1 in water pipe. Zinc die-cast body with screw clamp design for common residential and light commercial grounding and bonding work.
What this product is for
The Nesco 620Z is a zinc die-cast water pipe ground clamp used to bond a grounding conductor to metal water pipe in the 1/2 in to 1 in trade size range. It is suited to residential and light commercial grounding and bonding work where a listed pipe clamp is required.
Use for
Use for attaching a bare copper grounding conductor to copper or other metal water pipe within the listed pipe size range. Commonly used at service grounding and bonding points where electricians need a compact clamp for 1/2 in to 1 in pipe.
Avoid for
Avoid using this clamp on non-metallic pipe, on pipe outside the 1/2 in to 1 in range, or where the installation requires a different clamp material or conductor range than the product listing allows. Confirm local code and the authority having jurisdiction before installation.
Best for
Best for standard indoor grounding and bonding connections on metal water pipe where a zinc die-cast clamp is acceptable and fast installation matters.
Installed in
Typically installed in houses, small commercial buildings, service rooms, mechanical spaces, and renovation projects with accessible metal water piping.
Why this product exists
This clamp provides a simple mechanical connection point between the grounding conductor and metal water pipe, helping electricians complete compliant bonding work with a pipe-size-specific fitting instead of improvised hardware.
Compared with similar products
Compared with bronze ground clamps, a zinc die-cast clamp is a common economical choice for standard indoor applications. Buyers should verify conductor compatibility on the listing they are purchasing, as similar 620Z-style clamps are commonly shown for 1/2 in to 1 in pipe and often for bare wire ranges such as 10 AWG to 2 AWG, but conductor range should be confirmed on the exact product packaging or manufacturer listing.
