What is the primary purpose of Article 230 in the NEC?

The primary purpose of Article 230 in the NEC is to cover the requirements for overhead and underground service conductors. This article provides essential guidelines for the installation, maintenance, and operation of service conductors, which are critical for safely bringing electrical power from the utility supply to the building. It outlines the specifications for the types of conductors, their sizing, installation methods, and the necessary equipment, all aimed at ensuring safety and reliability in electrical service.

Understanding these requirements is crucial for electricians and contractors as they directly affect both the performance and safety of the electrical system connected to the utility company. This article ensures that service conductors can withstand the environmental conditions they may encounter, whether above ground or underground, thereby minimizing the risk of electrical hazards, such as short circuits and fires. Other areas, such as the installation of lighting fixtures or procedures for electrical inspections, fall under different articles in the NEC and do not pertain specifically to the focus of Article 230.
