What Is Knob & Tube Wiring?
Knob and tube wiring was commonly installed in homes from the late 1800s through the 1940s. It uses ceramic knobs and tubes to run wires through walls and framing.
While it was safe at the time, it was never designed to handle today’s electrical demands—and that’s where problems begin.
Why Knob & Tube Wiring is a Problem
Not Built for Modern Loads
Today’s appliances, HVAC systems, and electronics put far more demand on wiring than knob and tube was designed to handle.
Insurance Issues
Many insurance companies will not cover homes with active knob and tube wiring or require removal before issuing a policy.
No Grounding
Knob and tube systems lack grounding, which is essential for modern electrical safety.
