Building wires, a common term amongst electricians, are widely used in both domestic and commercial sectors. The term ‘building wires’ generally refers to the electrical wiring carefully placed in a room’s foundation. These wires are what distribute electric power to residential, commercial and industrial buildings. They are even utilized in mobile homes, recreational homes and vehicles, substations and even boats. Durably efficient, the interior of building wires is usually fitted with two insulated conductors, that are twisted together to form a firm unit.
