Knob and Tube Wiring – Know the Facts
Knob and tube wiring is one of the original forms of electrical wiring. While it once was cutting edge, it’s now considered a fire hazard.
- It’s Not Grounded. Knob and tube wiring has no ground wire. A ground wire is important because it causes the circuit breaker to shut off in case of a short circuit.
- It Deteriorates. Over time, the cloth insulation over the copper wires deteriorates and the soldered connections become weak and brittle.
- It Can Create Arcing. Broken knob and tube wiring can result in electrical arcing. This is when sparks jump from one wire to another, causing a fire hazard.
As a result, insurance companies will demand higher premiums or refuse to insure homes with knob and tube wiring. If your insurance company is unaware that your home has knob and tube wiring and it creates a fire, you may not be covered for your loss.
