Knob and Tube
Knob and tube wiring is the original form of residential wiring. It is a system that consists of wires with ceramic knobs to support the wires on the building structure and ceramic tubes for where wiring passes through wood framing members.
How do I know if I have knob and tube wiring? Knob and tube wiring was used in homes constructed or electrically wired between 1900 and 1949. If you still have two-prong outlets or push button switches, there is a very good chance your home is still utilizing knob and tube wiring in many locations.
If I have knob and tube wiring, is it safe? Typically a knob and tube wiring system that has never been touched or expanded can continue to operate reliably and safely. However, due to the number of connections buried behind the walls, there is no way to know if there have been modifications made to the system since it was originally installed. For this reason, it has been deemed unsafe for current electrical requirements and many home insurance companies will not offer coverage for homes where knob and tube wiring is still active.
Many of our clients believed that their home was remediated in the past when, in fact, only the visible wiring in the basement and attic were removed, leaving the remainder of the house operating with the knob and tube system.
