What Is Knob & Tube Wiring?

Knob and tube wiring is an older style of wiring commonly found in homes built before 1950. Also called K&T wiring, it works by running copper conductors through tubes tied down with porcelain knobs—hence the name. Unfortunately, this style of wiring can be relatively dangerous; it’s not grounded, which poses a huge safety risk to both appliances and people. In addition, all the wires are wrapped in a rubber cloth, which can deteriorate over time—causing potentially serious problems.

There are a couple of ways to figure out if you have knob & tube wiring. First, check the basement or attic. If you notice heavy ceramic tubes and white, spool-like knobs, then you likely have this type of wiring. Second, check your outlets. A grounded outlet should have three prongs and, if they don’t, there’s a decent chance that you have knob and tube wiring.

Unfortunately, knob and tube wiring is sometimes hidden, making it difficult to detect. As such, it’s important to contact a licensed electrician for assistance.
