Why You Should Hire a Professional to Install Your EV Charger

Bryan Lee • June 10, 2025

With EVs becoming more common in driveways across San Antonio, many homeowners are looking to install a Level 2 charger at home. While some chargers may seem plug-and-play, the reality is this: installing an EV charger safely and correctly requires far more than plugging in a cord. At Seven Petal Electric, we’ve helped dozens of customers get their EV chargers installed right—the first time. Unfortunately, we’ve also been called in to fix DIY or handyman installs that were unsafe, underpowered, or flat-out non-compliant. Here’s why hiring a licensed electrician isn’t just smart—it’s necessary.


EV Chargers Draw Serious Power

Level 2 chargers operate on 240 volts and can draw 40–50 amps continuously. That’s more than many air conditioning systems. This means your wiring, breaker, and panel all need to be evaluated and (if needed) upgraded to safely handle the load.

Using the wrong wire size or breaker type could result in:

  • Overheating wires
  • Tripped breakers
  • Electrical fires
  • Damage to your vehicle’s charging system

Code Compliance Matters

Electrical work in Texas must meet National Electrical Code (NEC) and local permitting standards. EV charger installations often require:

  • Dedicated 240V circuits
  • Proper wire gauge and conduit
  • GFCI protection in certain locations
  • Permit and inspection approval

We’ve seen installations done without permits—and homeowners forced to rip it all out when selling or upgrading their home. Don’t risk it.

Professional Installation Protects Your Warranty

Many EV manufacturers and charger brands (like Tesla, JuiceBox, and ChargePoint) require professional installation to keep warranties valid. If there’s a fault due to improper wiring or an overload, they can deny coverage if the work wasn’t done by a qualified electrician.

We Make It Easy

When you hire Seven Petal Electric for an EV charger install, you get:

  • A consultation to assess panel capacity and charging needs
  • A detailed, code-compliant installation using quality materials
  • Permit pulling and inspection scheduling
  • Clean, professional work with minimal disruption to your garage or home

We also advise on smart chargers, load-sharing options, and integration with solar or battery systems, if applicable.

Ready to Charge Confidently?

EV ownership should be smooth and stress-free. Hiring a licensed electrician for your charger install ensures it stays that way.

A surge protector in San Antonio
By Bryan Lee June 10, 2025
Recently, we got a call from a homeowner whose generator system stopped working. The culprit? Two fried automatic transfer switches—both damaged beyond repair by a power surge. These weren’t cheap parts, and replacing them wasn’t cheap either. But instead of just fixing the immediate problem, we took it a step further and installed a whole-home surge protector. That decision may save the homeowner thousands more down the road.

For many families, a power outage is a short-term inconvenience. But for people who rely on medical equipment, it can be life-threatening. At Seven Petal Electric, we recently worked with a couple who relied on home medical devices. After losing power during a storm, they realized how vulnerable they were. When they called us, their number one concern was safety and reliability. We installed a whole-home backup generator specifically sized for their electrical needs. Now, when the grid goes down, their generator starts up automatically—restoring power in seconds. There’s no fumbling with cords or waiting for someone to fix a blown transformer. Their devices keep running, even if the rest of the neighborhood goes dark.
