Here are some of the most common signs of faulty electrical wiring in a home:

• Flickering or dimming lights: While your lights could be flickering due to a loose bulb or an incompatible dimmer switch, flickering and dimming could also be caused by bad wiring. If the issue occurs when using multiple applications, that’s a definite sign that your wiring needs professional attention.
• Circuit breaker trips: These electrical safety devices are designed to trip to prevent short-circuiting and overloading. However, circuit breakers that fail frequently usually indicate an issue with the home’s wiring.
• Frayed wires: Wires can fray due to age, rodents chewing through the insulation or other forms of damage. Regardless of the cause, frayed wires are not only an obvious sign of faulty wiring but also an electrical fire and shock hazard.
• Hot outlets and switch plates: Outlets and switch plates should never feel hot. While switch plates may become slightly warm due to an electrical current, they should still be comfortable to touch. If you notice these hot spots, your wiring may be faulty.
• Sparking: Large sparks coming from the breaker panel, fuse box, or outlets are clear indications of electrical fault and need immediate attention.
• Buzzing sound: A consistent and loud buzzing sound may signal an electrical problem, especially if it’s coming from a switch, outlet or appliance. The sound may be a result of loose wiring.
• Burning or odd smells: Burning, smoky or strange odors from your outlets or electrical panels are another sign of faulty wiring that must be addressed urgently.
