The Hidden Dangers of DIY Electrical Projects: When to Call an Electrician

Those DIY kitchen cabinets turned out fabulous.

You even put in your own tile backsplash to finish off the look.

It’s too bad the outlets above the counters still aren’t working.

And the light above the table keeps flickering.

There’s just some things you can’t (or shouldn’t) DIY—especially those that can result in a shock.

We want to caution you about DIYs when electricity is involved.

Cutting a wire too short can create a fire hazard and put your home out of code compliance.

Forgetting to switch off the breaker before using those metal pliers could end in a trip to the hospital.

DIY electrical projects are no joke and we want everyone to stay safe and within their expertise level.

What You Need to Know About Electrical DIY

The Dangers of DIY Electrical Work

Electrical work requires a thorough understanding of codes, safety standards, and proper techniques.

Without this knowledge, you can put yourself at risk of electrical shock, fire, and other hazards.

Not Using Safety Equipment and Techniques

Professional electricians use specialized tools and equipment to perform their work safely. 

They also follow strict safety protocols to protect themselves and the occupants of the home.

DIYers, on the other hand, often lack this equipment and may not be aware of the necessary safety measures.

Making Costly Mistakes

While DIY projects are often undertaken to save money, the cost of fixing mistakes can far exceed the initial savings. 

Rewiring, repairing damage, and addressing safety issues can be expensive and time-consuming. In many cases, it's more cost-effective to hire a professional from the start.

Ignoring Electrical Codes

Electrical codes are in place to ensure the safety and reliability of electrical systems.

These codes are complex and regularly updated to incorporate new safety standards. 

Licensed electricians stay current with these changes, ensuring that all work performed meets or exceeds code requirements.

Common DIY Electrical Projects & Mistakes

Faulty Light Fixture Installations

You may feel confident swapping out old fixtures for new ones, but this seemingly simple task can lead to serious problems if not done correctly.

Loose connections, improper grounding, and overloaded circuits are just a few of the issues that can arise.

Connecting the new fixture using the old wiring can lead to flickering and a significant fire hazard if the wire is too old and not up to code.

Overloaded Circuit Breakers

You can’t add extra outlets in a room without considering the load it will place on the existing circuit. This can result in frequent tripping of the breaker or, worse, an electrical fire.

Adding several new outlets to your garage but having them all run on the same circuit will likely overload it the first time you turn on multiple power tools. It’ll blow and not only put you and everyone else in the garage at risk, but hurt your whole system.

Inadequate Grounding and Bonding

Without adequate grounding, there is an increased risk of electric shock and fire.

It ensures that all metal parts within an electrical system are securely connected, providing a clear path for electrical current to travel safely to the ground.

Attempting to upgrade your electrical panel but neglecting proper grounding will leave it full of electrical faults and potential shock hazards.

Incorrect Wire Sizing

Each circuit in your home is designed for a specific wire gauge, and using a wire that is too small for the amperage can cause overheating and potentially start a fire.

If you use a 14-gauge wire for a 20-amp circuit, which should have had a 12-gauge wire, the undersized wire will overheating and cause the breaker to trip.

Where to Draw the Line: DIY vs. Professional Help

So, where should you draw the line between what you can safely do yourself and when you should call an electrician? Here are some guidelines:

For Homeowners with Electrical Experience

If you have experience with electrical work and feel confident in your skills, it’s important to use the correct guides, use the correct tools, and follow all safety protocols.

However, if you’re ever unsure about a project or don’t have the recommended tools in your garage, it's better to call your local electrician than to risk your safety.

Remember, the expertise of a professional can prevent costly mistakes and ensure the job is done right.

Tasks for an Electrician

Installing New Circuits or Outlets: This requires an understanding of load calculations and proper wiring techniques.

Fixing Flickering Lights or Frequent Breaker Trips: These symptoms can indicate underlying issues that require professional diagnosis.

Rewiring Projects: Whether it’s a single room or an entire home, rewiring should always be done by a licensed electrician to ensure safety and code compliance.

Upgrading Electrical Panels: This complex job involves high voltages and must meet code requirements.

FAQs

Can I install a new light fixture myself?

Yes, you can install a new light fixture yourself, but it's important to ensure the power is turned off at the breaker before you begin.

However, if you're unsure about the wiring or if the fixture requires additional support, it's best to call an electrician to avoid any potential hazards.

What are the risks of doing electrical work without proper knowledge?

DIY electrical work without proper knowledge can lead to serious risks such as electrical shocks, fires, and damage to your home’s electrical system.

Mistakes like improper grounding, incorrect wire sizing, or overloading circuits can have dangerous consequences.

How do I know if my home’s electrical system is up to code?

An electrician can perform an inspection to determine if your home’s electrical system meets current codes and safety standards.

This is especially important if your home is older or if you've recently completed DIY electrical projects.

What should I do if my circuit breaker keeps tripping?

If your circuit breaker keeps tripping, it could be a sign of an overloaded circuit, a short circuit, or a ground fault.

It’s important to identify the cause to prevent potential hazards. An electrician can diagnose and fix the issue safely.

When should I call an electrician instead of doing it myself?

You should call an electrician for tasks such as:

  • installing new circuits or outlets

  • upgrading your electrical panel

  • fixing flickering lights or frequent breaker trips

  • rewiring projects

If you’re ever unsure about a project or don’t have the necessary tools and expertise, it’s safer to call a professional.
