What does NEC Article 230 primarily address?

NEC Article 230 primarily addresses the installation of service conductors and service equipment, which are critical components in the distribution of electricity to buildings. This article provides guidelines for the safe and effective installation of these electrical systems, ensuring that the service entrance, which includes the service conductors, disconnects, and other related equipment, meets safety standards and operates efficiently.

Understanding the guidelines in Article 230 is crucial for electrical professionals because it outlines requirements for the sizing, protection, and configuration of service conductors, as well as the proper installation of switchboards, panelboards, and transformers. Adhering to these requirements helps to protect both the electrical system and the occupants of the structure, maintaining safety and reliability in the supply of electrical power.

The scope of Article 230 makes it fundamental for any new electrical installation or modification involving service equipment, which is why it is considered essential knowledge for those working in the electrical trade.
