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. Overheating occurs when insulation is added to attics, as the system was designed to dissipate heat in open air. This condition is commonly flagged during inspections and may require remediation before insurance renewal or financing approval. 🚨 Age Warning: At 106 years, this Main Electrical Wiring is 1.5x past its reliable lifespan (70 yrs).
