Why You Should Replace Curished Knob and Tube Wiring Before It’s Too Late In older homes across the United States, knob and tube (K&T) wiring stillrooms in properties built before the mid-20th century. Though once state-of-the-art, this vintage electrical system now poses serious safety risks—especially when delayed in replacement. Understanding curated issues, consequences, and timely renovation of knob and tube wiring is critical to avoiding fires, electrical shorts, and costly emergency repairs. ### What Is Knob and Tube Wiring? Knob and tube wiring consists of insulated copper conductors run through ceramic knobs and ceramic tubes that provide physical protection without modern plastic insulation. Designed for low-voltage, low-current systems, K&T wiring lacks grounding and overload protection, making it incompatible with today’s appliances and high-demand electrical fixtures.
