Uncovered Junction Boxes Illustration by Ian Warpole For older, unmarked fixtures, use only 60-watt bulbs or smaller. Solution: Stay within the wattage limit listed on all light fixtures made since 1985. The damage to socket and wires remains even after the bulb has been removed. The bulb’s intense heat can scorch or melt the socket and insulation on the fixture’s wires, which increases the risk of arcing - sparks that jump through the air from one wire to another - a chief cause of electrical fires.
What it means: A fixture has a light bulb with a higher wattage than the fixture is designed for.ĭanger level: High. Remember: Anytime you work with wiring, be sure to turn off the circuit at the main breaker panel. To help you assess the state of your own electrical system, we’ve asked Gallant to identify the 10 most common wiring problems he sees, the dangers they pose, and his recommended solutions.

Code only requires you to update wiring in rooms being gut-renovated. Each time the electrical code is revised, old wiring is “grandfathered,” on the assumption it was installed correctly. After that, he recommends getting a quick follow-up inspection every five years.ĭon’t be alarmed if the inspection turns up code violations. “He’ll look at the insulation on the wires to see if it’s dried out and fraying, he’ll look for corrosion in the service panel, and he’ll look to see if a previous owner did anything unsafe,” Gallant says. If you’re buying a house (especially one that’s more than 50 years old), or if you’ve never had your wiring inspected, it’s a good idea to hire a licensed electrician to give your home a thorough going-over. But others can pose serious fire or electrocution hazards. Some wiring problems are just inconveniences. To fix it, the old circuit must be rewired. Once the insulation has been damaged, the danger remains even if the offending fuse is replaced with one that’s the proper amperage.
That can cause the wires to overheat, damaging their protective insulation and increasing the risk of fire. Protecting the Fuse Boxįuse boxes, like the one above, are less common these days than circuit breaker panels, but they work just fine - unless someone installs fuses with a higher amperage than the wires can safely handle. The signs of strain may be obvious-a tangle of extension cords and power strips sprouting from a single outlet-or lurking unseen behind walls, ceilings, and cover plates.

“The circuits in these older homes weren’t designed to power the many gadgets of modern life,” says electrician Allen Gallant, who has wired six This Old House TV project houses. The wiring inside many houses is also out of date, straining to supply our ever-growing collection of electricity-hungry appliances, lighting, and electronics. It’s not just the nation’s power grid that’s antiquated.
