Which NEC Article covers Remote Control, Signaling, and Power-Limited Circuits?

• A. NEC Article 725
• B. NEC Article 727
• C. NEC Article 760
• D. NEC Article 800

Answer: (A)

The concept being tested is how the NEC organizes low-voltage control and signaling by placing it in a single article that specifically addresses remote-control, signaling, and power-limited circuits. This article is written to cover circuits that carry limited power and voltage, so they pose reduced shock and fire hazards and are used for signaling and control rather than for powering large equipment. It sets the rules for what counts as power-limited, how these circuits are wired, protected, and installed, and it includes requirements for conductor sizing, enclosures, and wiring methods suitable for low-energy applications like remote controls, signaling circuits, and similar control circuits. That’s why this article is the correct reference for remote control, signaling, and power-limited circuits. Other choices address different topics. Fire-alarm signaling is covered by a different portion of the NEC with its own set of rules and safety considerations, while communications circuits are treated under another article focused on data and communications systems. Those areas, though they involve signaling or signaling-type work, are not the same grouping as the power-limited control and signaling circuits described here.
