Welcome to our comprehensive guide on Knob And Tube Wiring. Knob and tube wiring is a method of electrical wiring that was commonly used in homes in the late 19th and early 20th centuries. It consists of insulated copper conductors run within wall or ceiling cavities, passing through joists and studs, and supported along their length on insulating knobs or tubes. While this type of wiring has been largely phased out in modern construction, it is still present in many older homes.
