Grounding Rod HiSmart EL240203 D-20mm L-1.5m, copper/steel alloy, 1.5 m length

HiSmart EL240203 grounding rod is a copper-clad steel earth electrode with a 20 mm diameter and 1.5 m length, designed to form a reliable conductive connection to soil for grounding and lightning protection systems. The rod has a single pointed end for driving into the ground and two threaded ends compatible with M22 screw standard. The copper layer provides corrosion resistance while the steel core ensures mechanical strength.

Advantages

The copper-clad steel construction combines high conductivity of copper with the tensile strength of steel. A minimum copper layer thickness of 0.254 mm and 99.9% copper purity ensure long-term electrical performance and corrosion protection. Two threaded ends facilitate secure connections to clamps or extensions, and the 20 mm diameter with 1.5 m length offers a compact solution for residential and light commercial grounding needs.

Suitable for

• Earthing electrodes for residential electrical installations
• Lightning protection grounding rods
• Grounding systems in light commercial buildings
• Connecting to common grounding clamps and conductors

How to use

Select a suitable location for the earth electrode, avoiding large rocks and underground utilities. Drive the pointed end of the HiSmart EL240203 rod vertically into the ground using a hammer or rod driver until the required depth is reached or until only the threaded ends remain accessible for connection. Attach grounding clamps or conductors to the M22 threaded ends, ensuring firm mechanical and electrical contact. If additional length is required, connect compatible extensions by screwing them onto the threaded ends.

Usage recommendations

Install the rod according to local electrical and safety regulations. Verify soil resistivity and, if necessary, use multiple rods or supplemental grounding measures to achieve the required earth resistance. Use compatible clamps rated for M22 threads and periodically inspect the connection points for corrosion or loosening.
