Final answer:
Low-voltage system wiring is covered under NEC Article 725, which includes safety guidelines for the installation and use of various low-voltage systems. This is separate from other NEC articles that cover different aspects of electrical wiring and safety, such as grounding, underground cables, or swimming pool electrical setups.
Step-by-step explanation:
The National Electrical Code (NEC) is a widely adopted standard for electrical wiring and safety. Low-voltage system wiring, which includes cables and components that operate at lower energy levels, is specifically covered in NEC Article 725. This article provides guidelines and regulations for the installation and use of control circuits, signaling circuits, and power-limited circuits that don't exceed specified voltage and power limits. NEC Article 250 covers grounding and bonding, NEC Article 340 covers underground feeder and branch circuit cables, and NEC Article 680 covers electrical installations for swimming pools and similar areas.
The NEC aims to protect both property and human life from potential electrical hazards such as thermal and shock hazards. It achieves this by instituting safety measures like proper grounding, the use of circuit breakers or fuses to protect against thermal overload, and ensuring that certain standards are maintained throughout electrical installations. Remember, it is crucial to always adhere to local regulations and color codes for wire insulation to ensure safety and compliance.
