What kind of systems or structures can serve as grounding electrodes?

• A. Only commercial buildings
• B. Metal fences
• C. Local metal underground systems or structures
• D. Only metallic pipes

Answer: (C)

Grounding electrodes are critical components in electrical systems that help maintain safety by directing excess electricity away from structures and into the ground. Local metal underground systems or structures are particularly effective as grounding electrodes due to their ability to connect with the earth, providing a reliable path for electrical discharge. These systems can include various elements like metal water pipes, structural steel, or other metal components that are buried underground, all of which can enhance grounding efficiency and reduce the likelihood of electrical shock or fire hazards. It’s important to note that not all metal structures can serve this purpose equally; their effectiveness often depends on factors such as size, conductivity, and connection to the earth. This makes local metal underground systems a comprehensive and reliable choice for grounding electrodes, fulfilling the critical role of safely dissipating electrical currents.
