Knob-and-tube wiring (K&T) is an antiquated electrical wiring system. It was a standard design for commercial and residential installation from the late 1800s into the mid-1900s. Now, about 140 years after it became a popular option for home wiring, there are still many old buildings with knob-and-tube wiring. But, K&T has already long been considered insufficient and hazardous.
The remaining knob-and-tube wiring that is still in use today does not meet modern electrical wiring safety standards and does not perform at the level of today’s wiring systems. Even if K&T wiring in a home has not been the cause of any electrical incidents to date, you can predict that old, outdated wiring will become a source of trouble at some point. Due to the relatively high risk, homeowners are advised that many homeowner insurance companies will not insure houses with K&T wiring.
Here’s what you should know if you have K&T wiring in your home and why you should have knob and tube wiring replacements to upgrade your residential wiring system.
In a knob-and-tube system, the wires are routed from one ceramic knob to another in a series to create a particular circuit. The knobs placed throughout the building served as supports and insulators for the wiring running to each electrical outlet or appliance. At points where the wiring was to be run through floor joists or wall studs, the electrician drilled holes, inserted hollow ceramic tubes, and threaded the wiring through the insulating tubes.
Back in the days of K&T, electricians might use a rubber or cloth sleeving material called a loom to wrap the wiring. They ran the hot wire and the neutral return wire together, separated by a couple of inches, whereas today, the wires are bundled together, sharing the same outer sheathing.
Knob and tube wiring systems are not grounded. That makes having such a system in your home a severe safety hazard for your family and the entire neighborhood.
Here are some of the most significant issues with K&T wiring systems and reasons for a knob and tube wiring upgrade in your home:
