True or False: Driven grounding rods must be installed perfectly vertical.

Driven grounding rods do not need to be installed perfectly vertical to be effective. While a vertical installation is generally preferred for optimum performance, various factors can affect the installation, such as soil conditions, obstructions, and the specific requirements of the grounding system. A slightly angled installation may still provide a proper ground connection, although this can impact the resistance of the grounding system.

Grounding systems are designed to establish a low resistance path to the earth, and as long as the rod makes adequate contact with the soil and meets local electrical codes, a marginal deviation from vertical will not necessarily impair its effectiveness.
