What Is Knob & Tube Wiring?

Knob and tube wiring is the oldest standardized form of home electrical wiring. It was common in North American homes from about 1880 to 1950, which means this outdated wiring is still present in many historic homes. While it is considered obsolete, building codes in the North Shore don’t require the removal of existing knob and tube wiring. However, it is not permitted in new construction, and electricians strongly recommend replacing it for the safety and performance of your electrical system.

What Are the Dangers of Knob & Tube Wiring?

Knob and tube wiring is not inherently dangerous. The hazard arises from these factors:
  • Old age: Since knob and tube wiring was discontinued around 1950, any remaining installations are at least 70 years old. At this age, copper wires may be oxidized, and the wiring insulation may be cracked and peeling away.
  • Insulation enveloping the wires: With today’s emphasis on energy efficiency, many older homes have had insulation added to them. Unfortunately, surrounding knob and tube wiring with insulation can create a fire hazard.
  • Unable to meet modern electrical demands: The electricity requirements of homes in the early 1900s were nothing like they are today. Refrigerators, vacuum cleaners, air conditioners, ranges, and other appliances have higher amperage loads than knob and tube wiring is designed to handle. This can lead to overheating and potential electrical fires. Plus, with no ground wire, outlets have only two prongs, making it impossible to plug in three-pronged appliances.
  • Improper modifications: Knob and tube wiring is susceptible to incorrect splicing performed by amateurs. This effort to overcome the amperage limitations of knob and tube wiring can actually make it more vulnerable to overloading and heat damage.

How to Determine if Your Home Has Knob & Tube Wiring

First, consider the age of your home. If it was built before the 1950s, it could have knob and tube wiring. Visit the basement and look up at the exposed joists. Do you see white ceramic knobs nailed to the joists with electrical wires snaking through them? That’s knob and tube wiring. If your home doesn’t have a basement, check the attic for the same telltale sign between the floor joists.
