The Dangers of Broken Electrical Outlets

Electrical outlets are something most of us take for granted – we plug in our devices without thinking twice. However, broken or faulty outlets can pose serious safety hazards that shouldn’t be ignored. In this comprehensive guide, we’ll outline the potential dangers of broken electrical outlets and provide tips on how to identify, repair, and prevent issues.

What Can Go Wrong with Electrical Outlets

There are several problems that can occur with outlets, some more dangerous than others:

Loose Connections

Over time, the wires connecting the outlet to your electrical system can come loose due to wear and tear, vibrations, or overloading. This creates heat that damages the wires, insulation, and outlet components. Loose connections are a fire hazard and can also cause electrical shocks.

Faulty Wiring

Outlets that were incorrectly wired or have damaged wires behind them are extremely dangerous. Faulty wiring often leads to short circuits, arcing faults, and fires. This is why it’s critical to have a licensed electrician handle any outlet wiring.

Worn Parts

The contacts and terminals inside an outlet wear out over time. Worn or damaged contacts increase resistance, generating excessive heat that can melt plastics and ignite fires. The springs that hold plugs in place also degrade, causing loose connections.

Cracked/Damaged Cover Plates

Outlet cover plates are designed to prevent any exposed wiring or contact with the metal outlet box. Cracks or damage that exposes the internal parts of the outlet create a serious shock hazard, especially for children.

Grounding Issues

Ungrounded outlets or reversed polarity (hot and neutral wires flipped) greatly increase the risks of shocks and electrocution. Faulty grounding eliminates the safety system meant to prevent electricity from flowing through your body.


Drawing more power than the outlet is rated for through overuse of extension cords and power strips can overheat the outlet and wiring, eventually leading to meltdowns and fire.

Dangers from Broken Electrical Outlets

So what can happen if one or more of your outlets are damaged or malfunctioning? There are two primary risks – electrical shocks and electrical fires.

Electrocution and Shock Hazards

Exposed, fraying, or otherwise compromised wires and contacts substantially increase the chances of being shocked or electrocuted by an outlet. Any time you go to plug in or unplug a device, there is potential for contact with live wires if the outlet is faulty. The amount of electricity delivered in these cases can range from an uncomfortable jolt to severe injury or death.

Children are particularly susceptible, as their small bodies cannot handle as much electrical current. Faulty outlets, especially loose covers, present a major shock hazard to kids who may stick items into the receptacles. It only takes a few milliamps travelling through the heart to cause severe damage or cardiac arrest.

Electrical Fires

The other major hazard is electrical fires. Heat generation is unavoidable in outlet wiring, but it is normally dissipated safely if the outlets are in good condition. However, broken outlets with loose, corroded, or breached connections produce excessive, concentrated heating.

This heat damage eventually ignites surrounding combustible materials like drywall and wood framing. Electrical fires are especially dangerous because they spread so rapidly. Once ignited, open flames lick up through walls and along wires into insulation and other hidden materials. Fires originating from wiring faults kill hundreds of Americans per year.

Signs of a Faulty Outlet

Because the dangers from malfunctioning receptacles can be so severe, it’s important to regularly inspect your outlets and be mindful of any signs of problems. Here are some visual and functional clues that may indicate issues:

  • Unusual warmth or burnt smell coming from the outlet
  • Visible scorching or melted plastic around the outlet
  • Frequent circuit breaker trips and blown fuses when using the outlet
  • Loose receptacle cover plate
  • Unusual buzzing, sizzling or crackling noises when plugging in
  • Device plugs falling out of the outlet easily
  • Discoloration of the receptacle face and contacts
  • Flickering or dropping lighting when on the same circuit
  • Tingling or shock sensation when contacting plugs inserted in the outlet
  • Sparking, arcing or short flashes visible when plugging in devices

Any of these are signs of potential hazards requiring immediate investigation by a qualified electrician. Outlets displaying these warning signs should be taken out of service until inspected. It’s not worth the risk of continuing to use faulty and potentially dangerous receptacles.

Dangers from DIY Electrical Repairs

While a broken outlet may seem like an easy fix, there are risks if you try to tackle repairs yourself without proper electrical training and experience. Here are some of the hazards posed by DIY electrical work:

  • Touching live wires can easily cause severe shock or electrocution without proper precautions
  • Lack of understanding of electrical codes can lead to installations that cause fire or shock hazards
  • Incorrectly wired connections may appear to work initially but fail dangerously later under load
  • Undetected grounding, polarity and short circuit issues can lead to lethal shocks
  • Minor errors seem harmless but can lead to major hazards down the road

There’s also legal liability if your DIY work causes injury or property damage. Lawsuits or denial of insurance claims can result from unpermitted electrical work. Training and licensing requirements exist for electricians to ensure community safety.

Unless you have professional-level electrical skills, repairs beyond superficial issues like replacing a loose cover plate should be left to a licensed electrician. Improper work could make problems worse or fail to detect and fix hidden dangers. Don’t risk the safety of your home and family.

How to Identify Broken Outlets

It’s a good idea to periodically inspect all electrical receptacles and outlets throughout your home. Here are some steps for checking existing outlets or any outlet you suspect may be faulty:

Visual Inspection

  • Unplug devices and remove cover plate. Inspect for damage like cracked/melted plastic or scorch marks.
  • Look for loose, moveable parts or bent contact tabs. Wiggle plugs while inserted to check for looseness.
  • Check for discoloration, pitting or excessive gunk buildup on contacts indicating overheating.
  • Ensure no bare or loose wires are improperly exposed. Check insulation condition.

Physical Test

  • Plug a nightlight or lamp into the outlet, turn it on and look for flickering that may indicate a wiring issue.
  • Lightly tug on cords plugged into the outlet to check if they are loose enough to fall out easily.
  • Feel around the outlet with the back of your hand to check for abnormal heat which could signal problems.
  • Listen and smell for any signs of sizzling, crackling or burning smells when operating.
  • Check outlets with a circuit tester or voltage meter for wiring faults.
  • Inspect extension cords, power strips and devices plugged into outlets for damage.

Any observed issues should be inspected immediately by an electrician. It’s also wise to schedule general receptacle checks by a professional on a periodic basis as preventive maintenance.

Dangers from Moisture

Moisture reaching electrical outlets creates further shock and electrocution risks, especially when combined with receptacle damage. Here are some wet conditions to watch out for:


Electrical outlets positioned outside have constant exposure to rain, sprinklers and other wet weather. Regularly inspect outdoor outlets for water intrusion which can lead to short circuits. Ensure covers form a tight seal and use outdoor-rated receptacles with weatherproof housing.


High humidity in bath and shower areas can lead to moisture accumulation on bathroom electrical outlets. Avoid positioning outlets near bathtubs or showers which may splash water onto them. Use GFCI protected circuits and outlets in bathrooms for added leakage protection.

Kitchens, Laundries and Sinks

Leaks or splashing water near kitchen counters, sinks, and laundry rooms can expose outlets to moisture. Never handle electrical devices or appliances near water with wet hands or while standing in puddles on wet floors. Use GFCI outlets in kitchens, laundries, and other damp locations.

Floods and Storms

Flooding from heavy rains, plumbing leaks or broken pipes can inundate electrical outlets in any room and create major shock risks. After flooding, have outlets inspected before reuse even if they were not directly exposed to water. Discard and replace any outlets, wiring or breakers that have been underwater.


High indoor humidity can put outlets at risk, especially if mounted on exterior walls prone to condensation. Insulate walls and control indoor moisture to keep receptacles and wiring from being exposed to damp conditions if condensation forms.

Stay vigilant to keep all electrical outlets away from moisture sources. Water reaching damaged or worn outlets vastly increases the chances of dangerous shocks. Use special outdoor-rated, GFCI protected, and tamper-resistant outlets in any damp locations.

How to Fix a Broken Outlet

If you have identified any receptacles that are damaged or malfunctioning, prompt repairs are crucial to avoid both electrocution and fire risks. Here are repair steps to follow:

Circuit Panel Resets

Frequently tripped breakers or blown fuses indicate overloading issues that may be caused by faulty outlets and wiring. Correctly identifying which outlets are on the affected circuit is key.

Full Replacement

Receptacles worn out from age or heat damage should be fully replaced, not just spot repaired. Shut off the circuit breaker, verify it’s de-energized, remove the outlet and replace it with a new one matching amperage and connections.


Loose, damaged or incorrect wiring causes many outlet failures. This may require new wire runs that match the existing wiring gauge and materials. Reroute any exposed wires too close to edges and install secure connections.

Grounding Repair

If the ground connection is faulty, install a grounded outlet or run new ground wiring according to codes. Never remove the ground prong from a plug; this eliminates important shock protection.

GFCI/AFCI Installation

In wet areas or to protect against arcs/sparking, GFCI and AFCI outlets may need to be installed. They provide advanced protection from shocks, electrocution and fires caused by leakage currents and arc faults.

Replace Cover Plate

Ensure the outlet cover plate is correctly installed and forms a tight seal over the receptacle. Cracked or loose plates expose internal electrical contacts and should be replaced immediately.

Prevent Overloading

Check the amperage rating on the outlet and ensure excessive appliances and equipment plugged in aren’t overloading the circuit. This may require relocating devices to other outlets or installing higher capacity receptacles.

Hire an Electrician

Unless you are highly experienced with home electrical systems, repairs beyond routine outlet replacements should be handled by licensed electricians. They have the training, tools and knowledge to correctly and safely diagnose and fix complex wiring issues. Don’t take risks doing DIY electrical repairs.

Preventing Electrical Outlet Issues

Along with proper maintenance and repair of any currently faulty outlets, prevention of future problems should be a priority. Here are tips to improve electrical safety:

  • Inspect all home outlets regularly, at least once per year – look for warning signs and test for faults.
  • Replace any damaged, outdated or inherently unsafe receptacles. Upgrade to tamper-resistant and GFCI outlets where appropriate.
  • Never overload outlets – be mindful of amperage ratings and use power strips cautiously to prevent overheating wiring.
  • Keep outlets and plugs free of dust and debris which can trap moisture and cause short circuits.
  • Ensure protective faceplates are securely installed to prevent contact with internal wiring.
  • Label circuits clearly so you can easily shut off outlets before doing any work. Exercise caution.
  • Have home wiring inspected during real estate transactions to identity potential electrical hazards ahead of moving in.
  • When remodeling, ensure additional outlets are added properly by licensed electricians on adequate circuits.
  • Check outdoor outlets for water intrusion and use weatherproof covers and GFCI protection.
  • Make sure outlets near water sources are protected – use GFCI models and avoid direct moisture contact.
  • Consider having arc-fault circuit interrupters professionally installed to protect against dangerous arc faults.
  • Never overload extension cords or power strips. Don’t link them together in a daisy chain.
  • Ensure appliances and devices used are in good condition with no damaged cords or plugs.

Staying vigilant to identify and promptly repair any damaged outlets, avoiding overloads, and using GFCI protection will help keep your electrical system safe for your family. However, it’s still wise to have a professional electrician periodically inspect your home’s wiring. Catching and fixing problems early is the best way to protect against faults leading to catastrophic shocks and fires. Don’t take chances with electrical safety in your home.
