• D. Wiring methods for underground installations

Answer: (B)

The primary focus of Article 225 in the National Electrical Code is on the requirements for outside branch circuits and feeders. This encompasses guidelines that address the installation of electric supply systems designed to provide power to services, structures, and other equipment located outdoors. Outside branch circuits and feeders serve unique environments that may be subject to various external conditions, such as moisture, temperature fluctuations, and physical damage from external elements. Therefore, Article 225 outlines specific installation practices, materials, and protective measures to ensure the safety and reliability of these outdoor electrical systems. Understanding the significance of this article helps electricians and other professionals ensure compliance with NEC regulations while maintaining safety standards for outdoor electrical installations.
