What is the purpose of a grounding electrode conductor?

The purpose of a grounding electrode conductor is to connect the main electrical panel to the earth ground, which serves as part of the grounding system for a building. This connection helps ensure that electrical systems are safe by directing excess electricity, such as during a fault or lightning strike, into the earth. By providing a path for fault currents to safely dissipate, grounding reduces the risk of electrical shock and equipment damage.

An effective grounding system is essential for protecting both people and electrical devices within a building. The grounding electrode conductor plays a crucial role in establishing this system by ensuring that all electrical elements are safely connected to the ground, thereby maintaining the overall safety and integrity of the electrical system.
