Aging Wiring in Pre-1970s Homes
60-120 yrs
Wiring age in older homes
Shelby's Uptown historic district and surrounding neighborhoods contain homes built between the 1900s and 1960s with electrical systems designed for a handful of ceiling fixtures and a few outlets. Many still run original cloth-insulated wiring behind plaster walls. Decades of added appliances — window AC units, space heaters, electric dryers, modern kitchens — have piled demand onto circuits never designed to carry it. Arc fault conditions develop silently inside wall cavities, invisible until a fire starts.
