In addition to safety, what is another primary focus of Article 230?

The focus on reliability of the supply of electric service in Article 230 is essential because it ensures that electrical systems function properly under normal and abnormal conditions. This encompasses the ability of electrical conductors, service equipment, and distribution systems to maintain a continuous and effective flow of electricity to consumers. Reliability is critical not only for user satisfaction but also for the proper functioning of electrical devices and systems, as inconsistent or unreliable power can lead to failures or hazards.

Article 230 outlines the requirements for services, including the proper sizing of conductors, protection of equipment from overcurrent, and safe grounding methods. These provisions are designed to ensure that the electric service provided to buildings and properties remains stable and dependable, reducing the likelihood of outages and equipment damage. By prioritizing reliability alongside safety, the NEC establishes a framework that supports effective energy distribution in both residential and commercial settings.
