Knob & Tube Wiring

Knob & Tube Wiring: This is a style of wiring that was installed in many homes back in the 1920’s to 1940’s approximately. It is copper wire which is good, however the type of insulation on the wire back then usually over time can become brittle and start to crack and fall off.

This system was what we electricians call a loop system meaning think of a wire looping around the house and as you need a device you would just T-off to it. Most times these T’s were just a wire wound around another, soldered and taped. No boxes.

Unfortunately the tape eventually disintegrates. If you think you may have this style of wiring (age of house), then I recommend an inspection by a certified electrical contractor to determine if there is an issue.

Some insurance companies will require an inspection if there is any indication of knob and tube wiring and also may request a rewire to today’s standards in order to qualify for insurance coverage. This can be costly but essential.
