Understanding Electrical Hazards in the Home

Spotting these early signs of trouble can mean the difference between a quick repair and a dangerous house fire. In this brief article brought to you by Mr. Electric, we shed light on some of the most common and often overlooked electrical hazards hiding in plain sight.

If you'd rather have certified electricians investigate, then call or message Mr. Electric to schedule a convenient appointment today. We're also happy to arrange urgent assistance for as soon as possible.

Buzzing or Humming Outlets and Switches

You ever flip a light switch and hear a soft hum or buzz? It’s easy to chalk that up to imagination or an old fixture, but any sound coming from an outlet or switch usually signals trouble. Common causes are loose connections or overloaded circuits. Over time, that vibration and heat can degrade the wiring insulation. This increases the risk of arcing and fire.

Flickering or Dimming Lights

A momentary flicker when the dryer kicks on might seem normal, but consistent flickering or dimming points to voltage drops or loose wiring. Undersized wiring, corroded connections, or an aging panel can’t keep up with modern electrical loads, and they should be addressed as soon as possible! Sorting this out early protects your wiring, your electronics, and your household!

Warm or Discolored Outlets and Wall Plates

If you touch an outlet or its cover plate and it feels slightly warm, just know that it's your electrical system asking for help. Yellowing, darkening, or scorch marks means there's overheating. This can be caused by overloaded circuits, loose terminals, or faulty devices plugged into the outlet.

Whatever the cause, heat and burn marks are clear red flags that demand emergency electrical service. Don't wait for an electrical fire to ignite in the middle of the night. Call or message Mr. Electric for urgent assistance.

Frayed or Damaged Power Cords

Let's be honest: we’ve all tugged on cords, bent them at awkward angles, or run them under rugs “just this once.” Over time, these will take their toll. Damaged cords expose live conductors and will create shock and fire hazards. They're especially dangerous if they’re hidden under carpets, behind furniture, or near flammable materials.

Get in the habit of checking for cracks, splits, or bare wires in the insulation. Exposed copper or inner mesh braiding are big red flags! Unplug affected cords and switch off the circuit breaker to any connected wiring. Have an electrician rewire or replace compromised outlets and switches.

Outdated Wiring Systems

Homes built before the 1960s often feature knob-and-tube wiring or ungrounded two-prong outlets. Even homes from the ’70s might be problematic as they can have aluminum wiring which expands and contracts more than copper. Either way, these outdated systems simply weren’t designed for today’s power-hungry electronics.

Modernizing your wiring is not a DIY job, though. It requires a certified electrician to ensure safety and compliance with current building codes, industry standards, and regulations. Mr. Electric offers upfront price estimates on top-tier electrical service.

GFCI and AFCI Protection Missing

Bathrooms, kitchens, garages, and areas exposed to moisture are supposed to have GFCI outlets, or Ground Fault Circuit Interrupter outlets. Bedrooms and living rooms, meanwhile, benefit from AFCI outlets, or Arc Fault Circuit Interrupters. If your home lacks these protective devices, then you’re missing critical safeguards.

An easy way to identify these unique outlets is to check for "test" and "reset" buttons. If you have GFCI and AFCI outlets, then remember to check on them regularly and make sure they're working.
