5 Common Electrical Myths That Could Be Dangerous

Electrical myths are everywhere, and while some might seem harmless, believing the wrong ones can put your home and your family in real danger. At Meyer’s Companies, Inc., we’ve been handling homeowners’ electrical work for over 75 years across Northwest Indiana and South Chicagoland. We’ve seen firsthand what happens when these myths go unchallenged, and we’re here to set the record straight.

Here are five of the most common electrical myths we hear:

• A GFCI protects against all electrical hazards.
• Rubber shoes or gloves will protect you from electric shock.
• Household electricity isn’t strong enough to kill you.
• Extension cords are perfectly safe to use long-term.
• It’s okay to DIY electrical work if you’re careful.

Read on to learn why each of these beliefs is wrong, and what you should do instead.

Does a GFCI Protect Against All Electrical Hazards?

The Myth: Ground Fault Circuit Interrupters (GFCIs) make you immune to all electrical dangers in your home.

The Reality: GFCIs play a vital role in electrical safety, particularly in areas prone to moisture, such as bathrooms, kitchens, and laundry rooms. These devices work by detecting ground faults, instances where electrical current flows outside its intended path, and shutting off power before it causes harm. However, their protection is far from universal.

For example, GFCIs do not:

• Prevent overloaded circuits, which can overheat and spark fires.
• Detect faulty or aging wiring hidden behind walls.
• Stop fires caused by damaged insulation or loose connections.

Even with GFCIs, electrical hazards can still develop if your system isn’t properly maintained.

What You Should Do: Use GFCIs as one layer of a broader safety strategy. Schedule regular wiring inspections with a licensed electrician, especially in older homes.

Do Rubber Shoes or Gloves Really Protect You From Electric Shock?

The Myth: Standard rubber footwear or household gloves will keep you safe when working around electricity.

The Reality: Not all rubber is the same. Regular rubber-soled shoes and kitchen gloves offer little to no true electrical insulation. Here’s why:

• Only rubber rated and tested for electrical work provides meaningful protection.
• Electricity can still travel through other parts of your body.
• Moisture, wear, and impurities in everyday rubber reduce the minor protection it offers.

What You Should Do: Never rely on household items as a substitute for proper safety gear. Always shut off power at the breaker before touching anything electrical, and call a licensed electrician for any work beyond changing a lightbulb.

Is Household Electricity Too Weak to Be Dangerous?

The Myth: The electricity running through your home is low-level and won’t cause serious injury.

The Reality: This is one of the most dangerous myths out there. Standard household voltage in the U.S. runs at 120 volts, which is more than enough to be fatal under the right conditions. Consider:

• It takes less than 0.1 amps of current to disrupt the heart’s rhythm.
• Wet skin dramatically lowers the body’s natural resistance.
• Even brief contact with a live wire can cause cardiac arrest.

What You Should Do: Always treat electricity with caution, no matter how “small” the job seems. Turn off the circuit breaker before working on any electrical component, and use a voltage tester to confirm that no current is present. For anything more complicated, hire a licensed electrician.

Are Extension Cords Safe for Long-Term Use?

The Myth: Extension cords can be used as a permanent solution for powering devices.

The Reality: Extension cords are convenient, but they’re designed for temporary use only. Using them long-term can lead to serious safety issues, including:

• Overheating: Overloaded cords can generate enough heat to ignite nearby materials, such as carpet or furniture.
• Damage over time: Extension cords placed under rugs, furniture, or in high-traffic areas can become pinched, frayed, or damaged, exposing live wires.
• Inadequate power supply: Many extension cords aren’t rated to handle the power needs of larger appliances, increasing the risk of overload and fire.

What You Should Do: If you find yourself frequently using extension cords, it’s time to upgrade your home’s electrical system. Have a licensed electrician install additional outlets where you need them most. It’s a safer and more reliable solution that prevents accidents.

Is It Okay to DIY Electrical Work If You’re Careful?

The Myth: With enough research and caution, anyone can safely handle basic electrical repairs or installations.

The Reality: While DIY projects can be rewarding, electrical work isn’t something to take lightly. Even minor mistakes can have major consequences, including:

• Fires: Improperly connected wires can overheat and ignite, putting your home at risk.
• Code violations: DIY electrical work often fails to meet local building codes, creating legal and financial headaches when selling your home.
• Injuries: Without professional training, it’s easy to misjudge whether a circuit is live or how much current it carries, leading to serious injuries or worse.

Electrical systems are complex, and even seemingly simple tasks can go wrong quickly if you don’t know what you’re doing.

What You Should Do: Always call a licensed electrician for any project beyond the most basic tasks, like replacing a light fixture. Professional electricians have the training, tools, and experience to handle the work safely and make sure it’s up to code. It’s a small price to pay for peace of mind.
