Introduction to the NEC


Communication and Electric Utilities

With communication utilities (e.g. telephone or cable TV) or electric utilities, the NEC covers offices, because the general public or employees that are not qualified to work on electrical installations might be present in these locations.

The NEC does not cover utility installations in or on easements, rights-of-way, pole lines, and overhead structures used for a communication utility  or an electric utility. Even though these installations may present a significant hazard, the utility has exclusive control and can exclude them from public access.

The NEC does cover installations that are similar to those of communications or electrical utilities but that are located on private premises, such as an overhead power line that's owned by a company or institution and used to distribute power within their own campus. There may be other documents needed in addition to the NEC in order to deal with some of the detailed construction of an overhead power line.

For example, Article 399 requires documentation of the engineered design of such installations, but many of the documentation issues that must be considered are covered by other standards, such as ANSI/IEEE C2, National Electrical Safety Code®.

The NEC does not cover installations where the utility has exclusive control.
