Knob and tube wiring contains copper wiring (neutral and hot) run through tubes and knobs made out of porcelain. The wires are held in place with the help of knobs, generally in contact with various components like wooden beams and other parts of the house. On the other hand, the tubes shield the wire from coming in contact with drywall, wood, or any other thing capable of starting a fire due to overheating. If you also live somewhere with this type of wiring, there is a good chance that you will need to replace the knob and tube wiring and Kato Electrical is ready to provide you the best service.
