What is Building Wire?
Building wire and cable are integral components of a building's electrical system and are used in nearly all properties. Building wire comes in different types, sizes, and insulation ratings to fulfill various application requirements and safety standards. It is typically made from copper or aluminum. Copper wire is often the preferred choice as it is very strong, making it suitable for heavy-duty applications. Copper building wire is most often used for branch circuit wiring, which distributes electrical current within a structure or residence.
Common Applications for Copper Building Wire
Building wire carries electricity in homes, businesses, and industrial environments. Therefore, its typical applications include powering lights, outlets, appliances, machines, outdoor setups, and underground cables. In workplaces, copper building wire runs heavy machinery, computers, and specialized equipment that must withstand harsh conditions like heat and chemicals. Copper building wire is highly conductive and strong, making it a great choice for electrical systems. THHN wire, for example, has a bare copper conductor and is suitable for branch circuit wiring and other conduit and raceway applications.
