The Facts About Knob and Tube Wiring


If your home was built prior to 1950, there’s a good chance it still has knob and tube wiring in its walls. This type of wiring consists of ceramic knobs that hold wires in place and tubes that protect the wiring. One unique thing that sets knob and tube wiring apart from modern installations is that it has only two wires: a hot wire and a neutral wire. Because there is no ground wire, electrical shorts are not stopped by the wiring system and extra charge is not provided when needed.

To make their knob and tube system safer, many homeowners choose to have an electrician install ground fault circuit interrupters (GFCIs). Though they are not technically grounded, GFCIs are effective at blocking the electrical current when needed to prevent electrical issues.

Are You a Candidate for Bucks County Knob and Tube Replacement?

While adding GFCIs to a home with knob and tube wiring can counteract some of the problems associated with this type of installation, there are still many other issues that can arise. Homeowners with knob and tube wiring are at risk for:

  • Shorts and fires. In knob and tube systems, the insulation is made of rubber rather than modern-day plastic. Over the years, the rubber degrades and leaves the wires exposed, leading to a greater chance that a short will occur or a fire will start.
  • System overloads. Because they were designed at a time when electrical needs were generally much smaller, knob and tube installations usually aren’t equipped to handle powering the many appliances of today’s families. To make the system more capable, many contractors add new circuits to the installation. While this may fix the problem temporarily, it can also overload the system quite easily, thus causing a larger issue.
  • Insurance issues. Because knob and tube wiring can be dangerous, many insurance companies charge homeowners with this type of installation higher premiums, and some refuse to provide coverage at all unless the wiring is upgraded. Therefore, doing away with knob and tube wiring can save you money and make it easier to get insured.
