More About Knob and Tube
What is knob and tube?
Knob and tube (K&T) describes an obsolete method of wiring which dates back to the 1880’s and was widely used through the 1940’s. Knob and tube wiring was originally designed for electric lighting and was considered a passing fad that would likely be too expensive compared to the widely used gas lighting of the day.
This type of wiring consists of two conductors (hot and neutral) with no grounding that are stretched and secured along the wood beams by porcelain “knobs” and routed through porcelain “tubes” that were drilled through holes in the beams to keep the conductors away from contacting the wood and overheating the walls.
Why is knob and tube dangerous?
This type of system has no capability of grounding and is easily overloaded by modern electrical products in your home. There is no acceptable or safe method for repairing K&T wiring to make it support modern requirements without replacing the wiring system. For this reason, many insurance companies will no longer offer coverage for homes with knob and tube.
