Knob and tube wiring is a type of electrical wiring used in buildings that were constructed before 1950. It consists of two insulated wires, “knobs” and “tubes”, which run along walls and ceilings, supported by ceramic insulators. This type of wiring is still in use today, though it is considered outdated and unsafe. A knob and tube wiring diagram is a helpful guide for those wishing to understand this type of wiring.
