Knob-and-tube wiring is an early electrical system using separate wires for hot and neutral, suspended on ceramic insulators. It was standard in homes built before 1950 but lacks the grounding wire required by modern safety codes. Insulation deterioration can expose live wires, increasing fire risk.
