What does Article 225 say about bonding and grounding for outdoor circuits?

• A. They require no special treatment
• B. All circuits must be insulated
• C. They must be properly bonded and grounded
• D. They can only be bonded

Answer: (C)

Article 225 of the National Electrical Code (NEC) specifically addresses the requirements for outdoor circuits, placing a strong emphasis on the importance of proper bonding and grounding. In this context, bonding is the process of connecting electrical equipment and conductive materials to ensure there is no significant voltage difference between them, which helps to enhance safety by preventing electrical hazards. Grounding involves connecting electrical systems to the earth, which provides a path for electrical current in the event of a fault. Proper bonding and grounding are essential for outdoor circuits due to their exposure to environmental factors that can increase the risk of electrical shock and other hazards. Grounding helps protect against surges, lightning strikes, and accidental contact with other conductive materials. Ensuring that circuits are adequately bonded and grounded helps to maintain system integrity and safety for any operations involving outdoor electrical installations. The requirement for proper bonding and grounding underscores the NEC’s commitment to ensuring safe electrical practices, particularly in outdoor settings where conditions can vary widely and increase risks. Thus, recognizing that outdoor circuits must be properly bonded and grounded aligns with established safety protocols and helps protect people and property from electrical issues.
