  • Knob and tube wiring was commonly installed in homes built from the 1880s through the 1940s. The system uses ceramic knobs to support wires and ceramic tubes to pass wires through joists or walls. While it was considered innovative at the time, it lacks the insulation, grounding, and safety features required by modern electrical codes. Key characteristics of tube and knob wiring include:

    • Single-insulated copper conductors separated by air instead of protective sheathing
    • No grounding wire, which increases the risk of shock and fire
    • Open-air installation using ceramic supports instead of conduits or cables
    • Limited power capacity, unsuitable for today’s high-demand appliances

Why Knob & Tube Wiring Is Unsafe Today

If your home still contains knob and tube wiring, it may not be equipped to handle the electrical load of modern living. Common risks include:

  • Overheating due to limited amperage capacity
  • Insulation deterioration that exposes wires over time
  • No grounding protection, making shocks more likely
  • Fire hazards when in contact with insulation or building materials
  • Difficulty getting homeowners’ insurance, as many providers refuse to cover homes with active knob and tube systems

  • Two-prong outlets instead of three-prong grounded outlets
  • Visible ceramic knobs or tubes in your basement, attic, or crawl spaces
  • Frequent blown fuses or tripped breakers
