Picture yourself driving your car on the highway when all the of the sudden you see brake lights and are forced to slow down because of construction. As you come to a stop, you see workers repaving a damaged road. Now, cars begin to line up in front of you and behind you. Where do you go? Nowhere—you’re stuck.
A ground rod, also known as an electrode, is similar to this highway scenario. It acts as the only electrical path to dissipate static discharge voltage (such as lightning) into the earth. When that path starts to break down, the static discharge has nowhere to go and puts the whole system at risk.
Many times, engineers are given the choice between three types of ground rods: copper-bonded steel, copper clad ground rods or galvanized steel for grounding systems. However, one material reigns supreme when it comes to strength, service life and overall investment. Hint: it’s copper bonded steel.
Continue reading below to learn why copper is the better choice for grounding systems versus it’s steel alternative.
