Debunking Common DIY Installation Myths

Don't fall for these dangerous misconceptions about DIY EV charger installation

"I've done electrical work before, so I can handle this"

The Reality:

EV charger installation involves 240V circuits, load calculations, and code requirements far beyond typical household electrical work. Even experienced DIYers lack the training, tools, and legal authority to perform this work safely and legally. One mistake can be fatal.

"I can save $1,000+ by doing it myself"

The Reality:

When you factor in your time, tools, materials, and the risk of mistakes, DIY installation rarely saves money. Add in voided warranties, permit violations, insurance issues, and potential fire or injury costs, and DIY becomes far more expensive than professional installation.

"I don't need a permit for work on my own property"

The Reality:

Electrical work requires permits in virtually all jurisdictions, regardless of property ownership. Unpermitted work is illegal, voids insurance, complicates home sales, and can result in fines or forced removal. Building codes exist to protect you and your family.

"YouTube videos and online guides make it easy"

The Reality:

Videos cannot teach years of electrical training, don't account for your specific situation, and can't protect you from the dangers of high-voltage work. Many online guides contain dangerous misinformation. Professional electricians have knowledge that cannot be learned from videos.

"The charger is plug-and-play, so installation is simple"

The Reality:

While the charger itself may be straightforward, installation requires running 240V circuits, installing breakers, performing load calculations, ensuring proper grounding, and meeting code requirements. The charger is the easy part—the electrical work is complex and dangerous.

"I'll just hire an electrician to inspect my work"

The Reality:

Licensed electricians won't inspect or approve DIY electrical work—it's a liability issue. Building inspectors won't pass unpermitted work. Most electricians charge more to fix DIY mistakes than to do the job correctly from the start. You'll end up paying twice.

"My homeowner insurance will cover any problems"

The Reality:

Most homeowner insurance policies specifically exclude coverage for DIY electrical work or unpermitted installations. If a fire or injury occurs due to your DIY installation, your insurance company will likely deny the claim, leaving you personally liable for all damages.

"I can get a permit after I finish the installation"

The Reality:

Permits must be obtained before work begins. Attempting to permit work after completion is called "after-the-fact permitting" and many jurisdictions won't allow it. Even if permitted, inspectors may require opening walls to verify hidden work, adding significant cost and hassle.

The Only Acceptable DIY Role

Here's what homeowners can and should do—everything else requires a licensed electrician

What You Can Do

  • Research and select the right EV charger for your needs
  • Determine the best location for charger installation
  • Measure distance from electrical panel to charger location
  • Take photos of your electrical panel for electrician review
  • Get multiple quotes from licensed electricians
  • Verify electrician licensing and insurance
  • Prepare the installation area (clear access, move items)
  • Be present during installation to ask questions
  • Review completed work and documentation
  • Perform regular visual inspections and basic maintenance

Requires Licensed Electrician

  • Opening or working inside electrical panels
  • Installing circuit breakers or disconnects
  • Running any electrical wiring or circuits
  • Making electrical connections of any kind
  • Performing load calculations
  • Determining proper wire and breaker sizing
  • Installing conduit or electrical boxes
  • Mounting and connecting the EV charger
  • Testing and verifying proper installation
  • Obtaining permits and passing inspections

The Smart Homeowner Approach

Be an informed, engaged homeowner who makes smart decisions about equipment and location, gets multiple professional quotes, asks good questions, and verifies quality work. This approach gives you control over the project while ensuring safe, legal, professional installation. You save money by being an educated consumer, not by doing dangerous electrical work yourself.

DIY vs. Professional FAQ

I'm a licensed electrician in another state. Can I install my own EV charger?

It depends on your local jurisdiction. Some areas allow licensed electricians to work on their own property, while others require permits and inspections regardless. Even if allowed, you must still obtain proper permits, follow local codes, and pass inspections. Check with your local building department for specific requirements.

What if I just want to install a simple 120V Level 1 charger?

Level 1 chargers that plug into existing standard outlets typically don't require installation or permits. However, if you need to install a new outlet or make any electrical modifications, you need a licensed electrician and proper permits. Never modify electrical systems yourself, even for "simple" outlets.

Can I do some of the work myself to save money?

No. Electrical work cannot be partially completed by homeowners and partially by electricians—it's an all-or-nothing situation. Electricians won't take liability for work they didn't perform, and inspectors won't approve mixed DIY/professional installations. Attempting this approach will cost you more in the long run.

How much does professional installation really cost?

Professional EV charger installation typically costs $1,200-$2,500 for standard installations, including labor, materials, permits, and inspection. Complex installations or panel upgrades cost more. This investment provides safety, legal compliance, warranty protection, insurance coverage, increased home value, and peace of mind—far more valuable than any DIY "savings."

What happens if I do DIY installation and something goes wrong?

You are personally liable for all consequences. This includes medical bills from injuries, property damage from fires, legal fees, fines from building departments, costs to correct the work, and potential criminal charges in cases of serious injury or death. Your insurance likely won't cover any of these costs for unpermitted DIY electrical work.

Are there any situations where DIY installation is acceptable?

No. EV charger installation always requires professional electrical work by licensed electricians. There are no exceptions for "handy" homeowners, people with electrical experience, or simple installations. The risks are too high and the legal requirements too strict for DIY installation to ever be acceptable.

How do I find a qualified electrician for EV charger installation?

Use our electrician directory to find pre-screened, licensed professionals with EV installation experience. Verify licensing and insurance, check reviews, get multiple quotes, and ask about their experience with EV chargers specifically. Look for EVITP certification, which indicates specialized EV charging training.

Is professional installation really worth the cost?

Absolutely. Professional installation provides safety, legal compliance, warranty protection, insurance coverage, increased home value, and peace of mind. When you consider the risks and hidden costs of DIY installation—including potential injury, fire, legal issues, and voided warranties—professional installation is not just worth it, it's essential.

Final Warning: Don't Risk Your Life or Property

EV charger installation is not a DIY project. The apparent savings are not worth the risk of death, injury, fire, legal liability, or financial ruin. Professional installation by licensed electricians is not optional—it's essential for your safety, your family's protection, and your property's value.

If you cannot afford professional installation, you cannot afford an EV charger. Wait until you can do it right.
