Knob and Tube Wiring Replacement
Knob-and-tube or K&T for short was commonly used in buildings in North America from about 1880 to the 1940s. This system is considered obsolete and can be a safety hazard.
Knob and Tube Danger Facts
Danger #1
Though not dangerous in itself, dangers can accrue from this system due to its age, improper modifications, and situations where building insulation envelops the wires.
Danger #2
As knob and tube has no ground wire there is no protection against electric shock. Original two pronged outlets will not accept any three-pronged plugs.
Danger #3
It is treated differently in different jurisdictions. In some areas, it must be removed at all accessible locations, while others merely require that it not be installed in new construction.
When comparing knob and tube wiring with its modern counterpart it is much less resistant to damage. Knob and tube wiring is insulated with cambric or asbestos and is not rated for any exposure to moisture. Some older systems contain insulation with additives that may oxidize the copper wire. Knob and tube can become brittle and bending the wires may cause insulation to crack and peel away.
Knob and tube wiring is often poorly spliced with modern wiring, causing the majority of the issues and fire hazards.
