There are a variety of reasons why knob and tube wiring can be a dangerous safety hazard in a home.

  • K &T wiring is hazardous if it’s in close proximity to the fiberglass insulation installed in homes of today
  • The two different wire types (black and white) do not have ground wire to protect it against electrical shocks.

4. Codes and Insurance Companies

K & T wiring violate electrical regulations and codes in many states and regions. This can work against the homeowner.

These powerful electrical systems contained in these devices can overheat wires causing fires in homes.
