What does Article 411 address in terms of electrical systems?

• A. Appliances
• B. Lighting Systems Operating at 30 Volts or Less
• C. Fixed Electric Heating Equipment for Pipelines and Vessels
• D. Air-Conditioning Equipment

Answer: (B)

Article 411 of the National Electrical Code (NEC) specifically addresses lighting systems that operate at 30 volts or less. This article covers the requirements and safety protocols for low-voltage lighting systems, which are often used to provide illumination in various applications such as landscape lighting, signage, and residential exterior lighting. The rationale behind focusing on systems operating at this lower voltage is primarily safety; lower voltage systems reduce the risk of electric shock and are typically used in situations where higher voltages may not be necessary or safe. The requirements outlined in this article help ensure that installations remain safe, reliable, and compliant with the NEC standards. Understanding the regulations in Article 411 is crucial for electricians and other professionals working with low-voltage lighting systems, as it provides guidelines on installation practices, circuit requirements, and necessary protective measures. This ensures that both the installation and use of these systems are safe for both users and the electrical infrastructure.
