Knob and tube wiring is an early electrical wiring method used in homes and buildings primarily from the late 1800s to the mid-20th century. It consists of individual insulated copper conductors run through ceramic knobs and tubes, which keep wires separated and prevent contact with combustible materials. While innovative for its time, this wiring method has since been phased out in favor of modern electrical systems.
Homeowners often wonder, what does knob and tube wiring look like? It features porcelain knobs that secure the wires along framing, and ceramic tubes that allow the wires to pass through joists and studs. Unlike modern electrical systems, knob and tube wiring lacks a ground wire, which can increase the risk of electrical hazards.
