Which NEC Article covers Closed Loop and Programmed Power Distribution?

• A. NEC Article 725
• B. NEC Article 780
• C. NEC Article 800
• D. NEC Article 760

Answer: (B)

Closed-loop and programmed power distribution is about systems where power delivery is actively controlled and programmed, such as the power distribution used in medical environments that relies on programmable control to ensure continuous, safe operation. NEC Article 780 specifically covers Programmable Electrical Medical Systems, which includes the distribution and control of electrical power within medical setups and equipment that are programmable and may use closed-loop control to support patient care. This makes it the most relevant article for this topic. The other options address different areas—low-voltage Class 2/3 circuits, general communications circuits, and fire alarm systems—none of which focus on programmable power distribution in the same way.
