Electrical fires are the second leading cause of residential fires in Mecklenburg County, and the risk is disproportionately high in older Charlotte neighborhoods. Homes in Dilworth, Elizabeth, Plaza Midwood, NoDa, Chantilly, and similar areas were frequently built before modern electrical standards and may contain wiring systems that were adequate in 1950 but are not suited to today's electrical loads.
Knob-and-tube wiring, found in homes built before roughly 1940, lacks a ground wire and was not designed for modern appliances. It is not automatically dangerous if it is in good condition and not overloaded, but it should be inspected by a licensed electrician every few years. Signs of trouble include flickering lights, breakers that trip repeatedly, outlets that spark, or outlets that are warm to the touch.
Aluminum wiring was common in Charlotte homes built between roughly 1965 and 1973. It expands and contracts more than copper, causing connections to loosen over time. Loose connections arc and generate heat inside walls where no one sees them. Have an electrician check for aluminum wiring and, if present, install CO/ALR-rated outlets and switches or have the wiring pigtailed with copper.
Extension cords are among the most misused electrical items in any home. They are designed for temporary use, not as permanent wiring. Running extension cords under rugs, through walls, or behind furniture traps heat and creates a fire risk. If you need more outlets in a room, have an electrician add them. Do not daisy-chain power strips or plug high-draw appliances (space heaters, air conditioners, refrigerators) into extension cords.
Space heater fires spike in Charlotte during January and February, when temperatures occasionally dip below 20 degrees. Use only space heaters with auto-shutoff features, keep them at least 3 feet from curtains, bedding, and furniture, and plug them directly into a wall outlet rather than an extension cord. Turn them off when you leave the room.
