Buying Guide: Grounding Rods and Clamps

Ground Rods
The copper-bonded steel ground rod has a 99.9% pure electrolytic copper coating bonded to a nickel-sealed high strength steel core. The copper coating is a minimum of 10 mils. Each rod is roll-stamped with the ERICO name, length, diameter and part number.

Ground Clamps
The copper ground clamp is silicone bronze and made for use with copper-bonded ground rods. It is sized for 1/2 in. or 5/8 in. rods and is a standard duty clamp that connects rod to cable. Parts with UL approval are suitable for direct burial in earth or concrete, so check the part for that mark before burial use.

Frequently Asked Questions

What does Erico make?
Erico offers copper-bonded steel ground rods in 3/8 in. diameter and 4 ft length, along with copper ground clamps for those rods. Both products are grounding parts sold under the Erico name.

How do I choose the right size?
Check the diameter of your rod before ordering, since the clamp is sized for 1/2 in. or 5/8 in. rods. Match the rod length and clamp size to your installation plan, and follow the manufacturer's instructions. Have a qualified technician handle electrical grounding work.

Are the clamps suitable for buried use?
Parts with UL approval are suitable for direct burial in earth or concrete. Confirm the clamp you buy carries that mark before using it for a buried connection, and pair it with copper-bonded ground rods.
