Why should I replace my knob-and-tube wiring?

In addition to insurance issues, knob-and-tube wiring poses the threat of short circuits, overheating, and fatal accidents like shock and fires.

Knob and Tube Electrical Wiring

  • Ground Wire: Modern systems contain a ground wire that protects from serious electrical error, however knob-and-tube wiring lacks the security of a ground wire.
  • Insulation: The rubber insulation in knob and tube wiring breaks down and becomes brittle over time, exposing your home to bare wiring
  • Outdated: Knob-and-tube wiring, meant to withstand only 15 amps of electrical current, is often carrying much more than it can handle due to the demands of modern technology. Additionally, these systems use two-prong vessels that restrict use of some technology and appliances.
