Ways Experts Detect and Resolve These 10 Signs of a Faulty Electrical System
Your residential electrical system manages the lights, key appliances, entertainment systems and everything else permanently connected or plugged into an outlet. It’s extremely inconvenient when something suddenly fails, not to mention a possible safety hazard. Learn about the top 10 signs of a faulty electrical system and how to resolve each issue.
1. Dimming, Flickering or Humming Lights
If your light fixtures regularly dim, flicker or buzz, the specific circuits may be overloaded, or there could be a frayed wiring connection. Overloaded circuits create a fire hazard due to overheating wires. To fix the problem, first try re-tightening or replacing the problematic bulbs. If that does not fix the problem, next change the light switch or socket. For persistent problems, particularly if a buzzing sound is present, reach out to a professional to inspect your wiring and circuits.
2. A Burnt Plastic Odor
A burnt smell coming from outlets or appliances suggests overheating or burning wires, which could spark an electrical fire. Immediately disconnect power to the area using the related circuit breaker and unplug any devices connected to the outlet. Refrain from using the outlet until you’ve had it professionally looked at and tested after repairs.
3. Crackling or Scorch Marks on Outlets
If you notice sparks when plugging in or unplugging something or find scorch marks on one of the wall outlets, it’s a definite sign of damaged wiring or a short circuit. Sparks will happen if there’s exposed wires or a loose connection, producing electrical arcing strong enough to cause severe burns, appliance damage and even fires. Move everything away from the outlet and switch off the related circuit breaker. Have a licensed electrician check and potentially replace the outlet, as they can safely find and resolve any potential wiring issues.
4. Warm Outlets or Switch Plates
Outlets or switch plates that are warm to the touch may suggest things like circuit overloading or bad wiring. Heat may reach dangerous levels in situations where excessive electricity comes into contact with wires that aren’t rated to handle the load, increasing your vulnerability to an electrical fire. Disconnect all devices from the faulty outlet and turn off the circuit at the breaker. Reach out to an electrician so they can safely diagnose and resolve the issue.
5. Total Dependence on Extension Cords
Extension cords are convenient to have around, but they should never be permanent solutions. Inappropriate use can lead to overloaded circuits or tripping breakers. If the electric doesn’t have enough outlets to meet your electrical needs, hire an electrician to install one or two more outlets.
6. Wobbly Plugs
Plugs that repeatedly fall out of outlets means worn-out sockets. Over time, the metal contact points within the outlet can wear away, impacting their ability to grip plugs firmly. Shaky connections can cause arcing, an electrical fire risk. Replace any damaged receptacles with new ones. This is a straightforward DIY fix, but if you’re not comfortable trying to work with electricity, call a professional.
7. Missing GFCIs in Kitchens and Bathrooms
Ground fault circuit interrupters (GFCIs) are necessary in areas exposed to water or humid conditions, namely kitchens or bathrooms. When these rooms lack GFCIs, you’re more exposed to a dangerous electric shock if water reaches the outlet. Adding GFCI outlets is a good idea for a DIY project if you’re experienced with electrical work. That being said, hiring an electrician ensures proper installation and safety compliance.
8. Regularly Tripped Circuit Breakers or Blown Fuses
Circuit breakers and fuses protect your home by shutting off power when the system overloads or a fault is detected. If the circuit breakers trip or fuses blow over and over, this is usually a sign that your electrical system is struggling to cope with that high of a power demand, which can also eventually lead to overheating and fire hazards. Prevent overloading by unplugging devices and reallocating the electrical load safely between multiple circuits. If the problem persists, have an electrician assess the entire system and upgrade your electrical panel or wiring when required.
9. Frayed or Chewed Wiring
Age, wear and tear or even a new pest problem may be the cause behind damaged or chewed wires. Damaged wiring means the protective plastic coating is no longer covering the conductive metal, enhancing your risk of electric shocks and fires. Find and replace any damaged wiring you come across right away. This type of repair job is best left to a seasoned and insured electrician.
10. Outdated Wiring
Homes originally constructed in the late 1960s and early 1970s are more likely to have aluminum wiring, which corrodes more quickly than copper and causes fire risks. Even earlier homes from the 1880s to the 1940s may contain knob-and-tube wiring, which lacks a ground wire. These older systems are inefficient and more susceptible to overheating and failure. Consider having your home rewired with modern copper wiring. This major job should be left to a licensed electrician, as they have the essential tools and experience for safe, compliant work.
