Article 720 covers circuits operating at:

Article 720 of the National Electrical Code (NEC) specifically addresses circuits that operate at less than 50 volts. This encompasses a variety of low-voltage systems including signaling, control, and communication circuits. Such low voltage limits are crucial for applications where safety is a primary concern, as they reduce the risk of electric shock. The specifications under this article ensure that installations are safe and effective for their intended uses, while also adhering to standards that protect both the equipment and the personnel involved.

Understanding these parameters is essential for electrical contractors to ensure compliance with regulations and to utilize the appropriate materials and methods for low-voltage installations. By familiarizing themselves with Article 720, contractors can confidently handle projects that involve these types of circuits, ensuring they meet both code requirements and customer expectations.
