A multi-strand house wire is an electrical wire that is made up of multiple thin strands of conductive material, such as copper. The strands are twisted or braided together to form a single wire that can be used for electrical wiring in homes, buildings, and other structures. Multi-strand house wire is available in a variety of sizes and configurations, depending on the specific needs of the electrical application. It is commonly used for wiring electrical outlets, lighting fixtures, appliances, and other electrical devices in residential and commercial buildings.
