Electrical wire is a fundamental component in electrical systems, designed to conduct electricity safely and efficiently. It consists of a conductive core, typically made of copper or aluminum, surrounded by insulation. Wires come in various types, including solid and stranded, each suited for different applications. Common varieties include THHN, Romex® (NM-B), and XHHW-2, which are used in residential, commercial, and industrial settings. The selection of wire depends on factors such as voltage requirements, temperature ratings, and environmental conditions. Proper wire selection and installation are crucial for ensuring electrical safety and system performance
