Ways Experts Detect and Resolve These 10 Signs of a Faulty Electrical System
Your household electrical system operates your lights, key appliances, entertainment systems and anything else hardwired or plugged into the wall. It’s highly inconvenient when something acts up, not to mention a potential safety hazard. Learn about the top 10 signs of damage to the electrical system and how to fix it.
1. Fading, Flashing or Humming Lights
If your light fixtures frequently dim, flicker or buzz, the circuit might be overloaded, or there could be a loose wiring connection. Overloaded circuits pose a fire hazard because of the risk of overheating wiring. To resolve this problem, first try re-tightening or swapping out the faulty bulbs. If that doesn’t work, next change the light switch or socket. For especially stubborn problems, namely if a buzzing sound is present, call a professional to inspect your wiring and circuits.
2. A Burnt Plastic Odor
A melted plastic smell near outlets or appliances indicates overheating or burnt wires, which could cause an electrical fire. Immediately shut off power to the area by flipping the corresponding circuit breaker and unplug any devices plugged into the outlet. Refrain from using the outlet until you’ve had it professionally looked at and repaired.
3. Crackling or Scorch Marks on Outlets
If you see sparks when plugging in or unplugging something or spot scorch marks on a socket, it’s a clear sign of faulty wiring or a short circuit. Sparks may appear because of exposed wires or a loose connection, leading to electrical arcing strong enough to cause severe burns, appliance damage and even an electrical fire. Move everything away from the outlet and switch off the corresponding circuit breaker. Have a licensed electrician examine and potentially replace the outlet, as they can safely keep an eye out for any underlying wiring issues.
4. Hot Outlets or Switch Plates
Outlets and any switch plates that are getting hot to the touch will sometimes signal circuit overloading or faulty wiring. Heat accumulates in situations where excessive electricity reaches wires that aren’t capable of safely handling the higher current, increasing the risk of an electrical fire. Unplug any devices from the damaged outlet and turn off the circuit at the breaker. Reach out to an electrician so they can properly assess and fix the issue.
5. Heavy Reliance on Using Extension Cords
Extension cords are handy tools, but they aren’t intended to be permanent solutions. Inappropriate use may lead to overloaded circuits or tripping breakers. If your home doesn’t have enough outlets for your electrical needs, consider hiring an electrician to install additional outlets.
6. Loose Plugs
Plugs that easily fall out of outlets are a sign of worn-out sockets. Over time, the metal contact points inside the outlet can wear down, affecting their ability to connect plugs firmly. Unsecure connections can lead to arcing, an electrical fire risk. Switch out any loose receptacles with new ones. This is a fairly simple DIY fix, but if you’re uncomfortable working with electricity, call a professional.
7. Missing GFCIs in Specific Rooms Like the Bathroom or Kitchen
Ground fault circuit interrupters (GFCIs) are necessary in areas exposed to moisture, mostly kitchens or bathrooms. If these areas lack GFCIs, you’re at a higher risk for electric shock if water comes into contact with the outlet. Adding GFCI outlets is easy to make a DIY project if you’re experienced with electrical work. Alternatively, hiring an electrician ensures the very best installation and safety compliance.
8. Frequently Tripping Breakers or Blown Fuses
Circuit breakers and fuses protect your home by disconnecting power when the system experiences a power surge or a fault has been detected. If your home’s circuit breakers trip or fuses blow frequently, this means your electrical system is struggling to cope with that high of a power demand, which can lead to overheating and fire hazards. Prevent overloading by unplugging devices and reallocating the electrical load safely between multiple circuits. If the problem continues, have an electrician assess the entire system and upgrade your electrical panel or wiring when required.
9. Frayed or Visibly Damaged Wiring
Age, wear and tear or even rodents may be the underlying problem behind damaged or chewed wires. Damaged wiring exposes the conductive metal, which can increase your electrical system’s risk of electric shocks and fires. Replace any damaged wiring you come across immediately. This sort of repair project is best left to a certified electrician.
10. Old Wiring
Homes built in the late 1960s and early 1970s are more likely to have aluminum wiring, which corrodes faster compared to copper and causes fire risks. Even older homes from the 1880s to the 1940s could have knob-and-tube wiring, which is missing a ground wire. Older electrical systems are inefficient and more exposed to overheating and even premature failure. It’s a good idea to have your home rewired with today’s safer copper wiring. This major job requires a licensed electrician, as they have the essential tools and experience for safety and code compliance.
