Lesson 3 - Copper CableNECIn addition to voluntary standards for signaling and hardware design, network installations are governed by several layers of legally enforceable regulations. The specific regulations that apply to a project depend on a network's design, physical implementation, and geographic location. However, most U.S. network installations must conform to the rules specified in the NEC. The NEC is a set of safety standards and rules for the design and installation of electrical circuits, including network and telephone cabling. The NEC is developed by a committee of ANSI, and published every three years by the National Fire Protection Association. Its rules and standards are intended to prevent electrical fires and accidental electrocutions. The NEC has been adopted as law by many states and cities, and is usually enforced by the local building department. Any new network installation in such an area must pass an electrical inspection similar to that required for a building's power distribution wiring.
