Knob and Tube Wiring: Is Your Home Safe?


Do you know what kind of wiring was used in the building of your home? Chances are you don’t, but if you know how old your house is it’s not too difficult to figure out. Knob and tube wiring is known as the earliest form of residential wiring and if it’s still being used in your home today, it can be a serious hazard.


What is Knob and Tube?
This early form of residential wiring consists of a cloth-covered wire and a neutral wire, that run parallel to each other. To secure the wires to the framing of your house, ceramic knobs are used and ceramic tubes are used where wires cross or penetrate framing.

Why is it Dangerous?
As with most things in life, when knob and tube wiring grows old it tends to break down. This type of wiring cannot be grounded or spliced into a grounded circuit. What does this mean? It means that its connections can melt if too much current flows through them which can lead to an electrical fire. Building insulation can also cause knob and tube wiring to overheat, so if you still have it in your home it’s time for an upgrade.
