Importance of Proper EV Charger Installation
May 30,2025

Buying an EV is only the first step. The second is figuring out how to charge it conveniently. Some assume it’s as simple as plugging in a toaster or setting up a new appliance, but installing an EV charger isn’t a casual DIY job. When it’s done wrong, it can overload your electrical panel, violate code, or pose a serious safety risk. Mr. Electric is here to help. We’ve been called in after things have gone wrong, and the aftermath isn’t pretty. If you’re getting ready to install a charger or want to upgrade your current setup, keep reading to find out what matters most, what can go wrong, and how to get it right the first time.

Your Home Isn’t Automatically Equipped for the Job

EVs are power-hungry by design, and your electrical system needs to be ready to support that demand. Most Level 2 chargers run on 240 volts and draw between 30 and 50 amps. Your standard kitchen oven usually runs on 30 amps. Clothes dryers, too. Now imagine adding another high-demand appliance that you use every night for hours at a time without updating your panel, circuits, or grounding. Even newer homes aren’t always ready. Older homes are even more likely to have outdated wiring, undersized breaker panels, or insufficient grounding. Plugging in a powerful charger without making upgrades can put major stress on your electrical system. Wires can overheat, breakers trip, and if there’s no fail-safe in place, you could risk an electrical fire. Just because the charger powers on doesn’t mean it’s safe.

Importance of Proper EV Charger Installation

Permits and Code Compliance

If you’re thinking about skipping the permit process to save time or money, it’s not worth it. Most cities and counties require a permit for EV charger installation because you’re making a serious change to your home’s electrical system. One that, if mishandled, could impact the safety of your home and neighborhood. Permits make sure that the work is reviewed, inspected, and approved according to current safety codes. Failing to get a permit can lead to some expensive consequences:

  • Insurance may not cover damages from an unpermitted installation gone wrong.
  • Home appraisals or sales can get held up if a home inspector spots a charger that isn’t up to code.
  • Utility rebates or tax incentives may be off-limits if the work isn’t officially documented.

Performance Is All About the Setup

If you splurge on the best charger out there that’s Wi-Fi enabled, voice-activated, and compatible with every EV on the market, that’s great. But if the wiring is too thin, the breaker isn’t matched correctly, or the voltage fluctuates, you’re still in trouble. A charger is only as reliable as the system feeding it. Poor installs lead to slower charge times, inconsistent performance, or mid-cycle failures. An electrician looks at the full picture:

  • What’s the voltage drop across the wiring?
  • Is the breaker rated correctly for a continuous load?
  • Will your charger be exposed to weather extremes?
  • Are you planning to charge two vehicles at once in the near future?

Planning Ahead Means Saving Later

Smart EV charger installation always considers what you’ll need tomorrow. Right now, your household might have one electric vehicle. In a year or two, that number could double. Or maybe you’ll add solar panels, a battery wall, or switch to a time-of-use energy plan that makes overnight charging more cost-effective. If your electrical panel is nearly maxed out, now’s the time to consider an upgrade. If your garage isn’t insulated, that may affect where the charger should go or whether the cable needs protection from temperature swings. If you’re adding a smart charger that syncs with your phone or home automation system, you might need surge protection, conduit runs, or a dedicated Wi-Fi network extender. The right kind of upgrades will future-proof your system and save you from doing the work twice. A thoughtful install saves money long-term and keeps your home one step ahead as technology evolves.

Don't Treat This Like a DIY Project

It’s tempting to want to do it yourself. You can find charger kits online, follow a few YouTube videos, and maybe get the thing to work. But with electrical systems, it’s important to hire professionals to protect your home, your family, and your investment. When you hire electricians, you’ll get:

  • A system that meets code
  • A permit that passes inspection
  • An install that won’t overheat or short out
  • Support if something ever goes wrong

I called into Mr. Electric of Cincinnati West and was greeted by Greg. He was super polite and asked how he could help. He walked me through rewiring this antique fixture in my dining room and got me through mounting it with no issues at all. Greg was extremely helpful and patient and I will definitely be using him and his team again in the future!!

Greg's team is the best! Mr. Electric are responsive, dependable, professional and work with a sense of urgency. Mr. Electric is our dedicated electriation from now on. We had an emergency outage day before New years Eve. Greg responded to my request within minutes, and the crew came out to my house within 2 hrs. We were out of state, and Greg kept us informed of the progress every step of the way. We later on has to work with insurance and Greg provided all the paper work, and even talked to our insurance to help us get the coverage. James and Nicolas worked day and night on the new years Eve and New years day to help get the electricity back. We were able to spend the new years Eve at home all thanks to Nicolas and James's hard work.

We had a bad wind storm, a tree fell on my neighbors property and it managed to completely rip out the power supply to our building. James and Nick came out and assured me that they could fix it in a timely manner. That was an understatement! They were so kind, professional and caring (I have a mentally disabled child and they understood my frustrations) they had my power supply reconnected to the building and the power back on by the very next day! (NEW YEARS EVE!) Saving me a TON of money on food and shelter expenses (due to cold temperatures outside)! Hero's in real life don't wear capes, they do their jobs with compassion for others. Thank you James and Nick #Grateful on Elm Park Dr.

James did a super job. He went above and beyond to replace the outlet for my oven. Also, he changed difficult to reach light bulbs in my stairwell and upgraded the light switch. Finally, Greg efforts to find time to squeeze me in for a last minute appointment on a busy holiday weekend. I appreciate both of them and the work they did. More importantly, I felt like they treated me as if I were part of their family.
