What are the two main types of residential grounding systems?

• A. Floating and bonded systems
• B. Grounding electrode and bonding of service equipment
• C. Active and passive grounding systems
• D. Single-point and multi-point grounding

Answer: (B)

The two main types of residential grounding systems are indeed the grounding electrode system and the bonding of service equipment. The grounding electrode system provides a direct electrical connection to the earth, which helps to dissipate electrical surges—like those caused by lightning or electrical faults—thereby reducing the risk of electric shock and equipment damage. It often includes components such as ground rods, plates, and various electrodes that establish this vital connection to the earth. Bonding of service equipment refers to the practice of connecting all metal parts of the electrical system to ensure that there is a continuous path for electricity to flow back to the ground in case of a fault. This helps to maintain safety by preventing voltage differences that could lead to electric shock and ensures that circuit protection devices operate correctly in fault conditions. Understanding these two aspects of grounding is essential for maintaining safety and functionality in residential electrical systems. Other options mentioned may include concepts related to grounding but do not encapsulate the two fundamental purposes of grounding that are critical in residential settings.
