What are Some Common Myths about Electricity?
Electricity is one of the most powerful—and potentially dangerous—forces in our homes. It powers everything from our coffee makers to our HVAC systems, and yet, many of us know surprisingly little about how it works. Over time, a number of myths have developed around electricity, safety, and the people who work with it.
As licensed electricians serving Langley, BC and surrounding communities, we’ve heard it all. From well-meaning DIYers to homeowners hesitant to call a pro, misinformation can lead to serious risks—both to your safety and your wallet.
In this post, we’re setting the record straight. Let’s bust some of the most common myths about electricity and electricians, and help you stay informed, safe, and confident when it comes to your home’s electrical system.
⚡ Myth #1: Electricity Only Flows If Something Is Turned On
The Truth:
Just because a light, appliance, or switch is off doesn’t mean there’s no electricity present. Many wires still carry current even when the device isn’t actively being used.
This is especially true if a switch controls only the connection between the power source and the load (like a bulb), rather than isolating power at the circuit level.
Why It Matters:
Assuming wires are dead just because something is "off" is a major cause of electrical injuries. Only a trained electrician with a voltage tester or circuit tracer can confirm whether a wire is truly de-energized.
⚡ Myth #2: Rubber Shoes or Tires Will Protect You From Electric Shock
The Truth:
While rubber is an insulator, regular rubber-soled shoes or car tires are not designed to protect you from electrical shock. In most cases, they're simply not thick or pure enough to act as a reliable barrier.
Also, electricity always looks for the shortest path to ground. If you’re in contact with a conductive surface (like a ladder, pipe, or wet ground), those shoes won’t save you.
Why It Matters:
Electrical safety gear is highly specialized. Don’t rely on everyday clothing or gear to protect you during electrical work.
⚡ Myth #3: Low Voltage = Low Risk
The Truth:
Voltage is only part of the equation. It’s current (amperage) that actually causes harm to the human body. Even at voltages as low as 120V (common in residential homes), a high enough current can cause burns, muscle spasms, or even fatal heart arrhythmias.
For perspective:
As little as 0.01 amps can cause a painful shock.
0.1 amps can be fatal under the right conditions.
Why It Matters:
Never underestimate residential electricity. A small mistake with low-voltage wiring can still be dangerous—or deadly.
⚡ Myth #4: DIY Electrical Work Is Cheaper and Just as Good
The Truth:
Sure, it might seem cheaper upfront. But DIY electrical work that’s not up to code can:
Fail inspections when you sell your home
Cause serious safety hazards
Void home insurance claims
Lead to expensive repairs or rewiring later
In British Columbia, any electrical work done on your home must follow the BC Electrical Code, and in many cases, must be done by a licensed electrician with proper permits.
Why It Matters:
An unlicensed electrical job might save a buck today—but could cost you thousands down the road. And even worse, it could endanger your family.
⚡ Myth #5: Electricians Just “Pull Wire” – It’s Simple Work
The Truth:
Electricians are trained, certified professionals who spend years studying complex systems. They work with electrical theory, load calculations, safety standards, code compliance, and advanced tools daily.
The work may seem simple when done right—but that's because a skilled electrician is making it look easy. Behind every outlet or breaker box is careful planning, measuring, testing, and troubleshooting.
Why It Matters:
Respecting the trade means trusting the pros. A licensed electrician can do far more than “just run wire”—they help ensure your home’s safety and long-term efficiency.
⚡ Myth #6: Breakers Trip Because They’re Old or Faulty
The Truth:
Circuit breakers trip to protect you. A tripped breaker means something is wrong:
Overloaded circuit
Short circuit
Ground fault
Faulty appliance
Replacing or “upgrading” the breaker won’t fix the problem—it just masks it.
Why It Matters:
Repeated tripping should always be inspected by an electrician. Ignoring the warning signs could lead to overheating, arcing, or electrical fires.
⚡ Myth #7: Power Bars and Extension Cords Are Totally Safe Long-Term
The Truth:
Power bars and extension cords are designed for temporary use. Using them as permanent solutions—especially for high-draw appliances—can cause:
Overloaded circuits
Tripped breakers
Fire hazards
They’re also often misused by “daisy-chaining” (plugging one into another), which is a serious code violation and safety concern.
Why It Matters:
If you regularly rely on power bars, you probably need more outlets. An electrician can safely install more receptacles and redistribute your load.
⚡ Myth #8: It’s Safe to Work on Electrical If the Breaker is Off
The Truth:
Turning off the breaker is a good start—but it’s not a guarantee. There may be:
Mislabelled panels
Back-fed circuits (e.g., from solar systems or generators)
Multiple circuits sharing a junction box
Only testing with the right equipment can confirm a safe, de-energized system.
Why It Matters:
Never assume the power is off. Always test, verify, and when in doubt—call a professional.
⚡ Myth #9: Electricians Are All the Same—Just Pick the Cheapest
The Truth:
Like any trade, quality and experience vary. A licensed electrician with up-to-date knowledge of BC code, insurance, and a warranty-backed guarantee brings far more value than someone offering cut-rate pricing.
Questions to Ask When Hiring an Electrician:
Are you licensed and insured?
Do you pull the appropriate permits?
Do you offer a workmanship warranty?
Can you provide references or reviews?
Why It Matters:
Hiring the cheapest contractor might cost more in the long run. Choose based on qualifications, not just price.
⚡ Myth #10: If It Works, It’s Fine
The Truth:
Just because a light turns on or an outlet charges your phone doesn’t mean it’s safe. Behind the scenes, there could be:
Overloaded circuits
Loose or corroded connections
Improper grounding
Worn insulation
Electrical systems degrade over time, especially in older homes.
Why It Matters:
An outdated or poorly installed system can still function—until it fails catastrophically. That’s why routine inspections by a licensed electrician are a smart investment.
Bonus: Common “DIY Fixes” That Are Actually Dangerous
❌ Wrapping a blown fuse in foil
This bypasses the fuse entirely and can easily start a fire.
❌ Using indoor-rated fixtures outside
Exposure to rain and condensation can lead to shorts and corrosion.
❌ Replacing a 15A breaker with a 20A to stop tripping
If your breaker trips, it’s doing its job. A higher-rated breaker can cause the wiring to overheat and fail.
What Electricians Actually Do (That Most People Don’t Know)
Professional electricians do far more than change lightbulbs. Their work includes:
Full-service rewiring and panel upgrades
EV charger installations
Smart home integration
Lighting design (indoor and outdoor)
Home inspections and troubleshooting
Surge protection and backup power systems
And they do it all while adhering to strict safety and code compliance standards, often under less-than-ideal conditions.
