Electrical issues often start small, like dimming lights or a warm outlet, but they can escalate quickly into serious hazards, including fires. Call a licensed electrician for any electrical issues. But as a homeowner, it’s important to be aware of some warning signs so you don’t ignore them.
Main Takeaway:
Don’t wait for a burning smell to tell you there’s a problem. Keep an eye (and a nose) out for trouble spots to keep everyone safe. Call an electrician if you notice any of these.
Look at electrical outlets, switches, lights, and appliances for possible warning signs:
If you notice any of these warning signs, consult a licensed electrician to assess and fix potential problems. It's a good idea to have a complete electrical inspection every 3-5 years.
1. Burning smells from appliances or outlets:
Could indicate melting insulation or wiring. Turn off electricity to the outlet at the main panel.
2. Hot walls near outlets or switches:
Could indicate hidden wiring issues.
3. Warm or discolored outlets and switches:
Could be a sign of overheating and potential fire risk.
4. Buzzing or crackling sounds:
Could indicate arcing or faulty wiring. Arcing is when electricity jumps off its intended path, typically due to damaged wiring or a loose connection. It creates heat and sparks that can ignite nearby materials.
5. Sparks from outlets:
One small spark when you plug something in is often normal, but big, extended sparks could indicate a problem. Also, normal sparks tend to be blue, while not-so-normal sparks tend to be white or yellow.
6. Flickering or dimming lights:
May indicate loose wiring or overloaded circuits.
7. Frequently tripped breakers or blown fuses:
Could be overloaded circuits, a short somewhere, or an undersized electrical panel. For most standard homes, 200 amp panel is common, but older homes may have 100 amp or even 60 amp.
8. Loose plug connections:
Outlets that don't hold plugs securely can cause arcing.
Other electrical issues:
Use of extension cords as permanent solutions:
Indicates insufficient outlets; consider adding more to reduce fire risk. Likewise, don’t use extension cords in an attic or crawl space for any long-term use. Extension cords are meant to temporarily extend the reach of electricity.Outdated two-prong outlets:
These lack proper grounding; consult an electrician to determine the best options. Just installing a three-prong outlet doesn’t protect against ground shocks; it only allows you to plug in a three-prong plug. If you own an older home with three-prong outlets, you can verify if the three-prong outlets are grounded and wired correctly using an inexpensive three-prong outlet tester.
Absence of GFCI outlets in wet areas:
Kitchens, bathrooms, and outdoor areas should have GFCIs to prevent shocks. But just because you don’t see outlets with a button on them, they might still be GFCI protected. You could have a GFCI breaker protecting the whole circuit. Or, a GFCI outlet further up on the circuit loop could be protecting downstream outlets.
The fine print:
The Solo Homeowner's Manual offers general educational information, not professional or safety advice. Every home is different. For anything involving electrical, structural, gas, or other safety concerns, consult a licensed professional, and in an emergency, leave and call 911 or your utility. You're responsible for decisions about your own home.
