Common reasons to call
- Just bought an electric vehicle and need a Level 2 charger at the house so it charges overnight
- Tired of slow charging on a regular wall outlet and want a faster 240-volt setup in the garage
- Adding one or more charging stations at a shop, office, or fleet yard for work vehicles
- Moving into a home that has no charger and wants one wired in the garage or carport
- Getting a wall connector installed to match a new car brand's recommended equipment
- Panel or breaker keeps tripping when charging on the current setup and needs a proper dedicated circuit
- Wants the charger mounted outside for a driveway spot instead of the garage
Typical work
- Installing a Level 2 (240-volt) home charger on a new dedicated circuit in an attached garage
- Running a dedicated circuit and outlet (like a NEMA 14-50) so a plug-in charger can be used
- Mounting and wiring a wall-connector unit on an exterior wall for driveway or carport parking
- Adding a subpanel or upgrading the main electrical panel when the current one lacks spare capacity
- Installing multiple charging stations at a business, office lot, or fleet parking area
Typical turnaround
Most home installs are done in a few hours to a single day once the charger and materials are on hand; jobs that need a panel upgrade or a permit and inspection can span a few days to a couple of weeks depending on the local permit office.
Materials and equipment
- Level 2 EV charging unit or wall connector
- Dedicated 240-volt circuit breaker

- Optional load-management device or subpanel
Job sizes
Minor
A small job where the electrical panel sits close to the parking spot with open breaker space, so the run is short and simple
Standard
A typical install with a moderate wire run from the panel to the garage or exterior wall, a new dedicated circuit, and the charger mounted and tested
Major
A larger job needing a long or trenched wire run, an outdoor install, or a panel that is full and needs a subpanel added
Replacement
Swapping out an old or failed charging unit, or upgrading the main electrical panel first because it cannot handle the added load
Final pricing comes from the on-call provider after on-site assessment, with a written estimate before any work starts.
What to expect
- ✓A good electrician runs a load calculation on your panel before quoting, so the added charger will not overload your electrical service.
- ✓The work should be done on its own dedicated circuit sized for the charger, not shared with other outlets or appliances.
- ✓A licensed electrician pulls the required permit and schedules the inspection, so the install is on record and meets the National Electrical Code.
- ✓A careful pro asks where you park and which vehicle you drive so the charger, outlet type, and wire run match your setup.
- ✓Outdoor installs should use weatherproof equipment rated for the heat, humidity, and coastal air of South Texas.
- ✓A reputable installer carries liability insurance and can show proof of their Texas electrical license on request.
- ✓A good pro will tell you honestly if your panel needs an upgrade first instead of overloading an old one.
A licensed electrician (TDLR master or journeyman) carrying general liability insurance; some also hold manufacturer certifications for specific charger brands and follow the National Electrical Code (NEC)
Common questions
Do I really need a licensed electrician, or can I do it myself?
A Level 2 charger runs on a 240-volt circuit and pulls a lot of current, so most cities require the work to be done by a licensed electrician and to pass a permit and inspection. Doing it yourself can create a fire risk, void your equipment warranty, and cause problems with your home insurance. It is worth having a pro handle the wiring.
What is the difference between Level 1 and Level 2 charging?
Level 1 uses a standard 120-volt wall outlet and charges very slowly, often adding just a few miles of range per hour. Level 2 uses a 240-volt circuit, like an electric dryer or oven, and charges several times faster, usually filling most cars overnight. Most people who install a home charger are moving to Level 2.
Do I need a permit for a home EV charger?
In most Texas cities you do. The electrician pulls the permit and the local building department inspects the finished work to confirm it meets the National Electrical Code. Ask your electrician to confirm what your specific city or county requires, since rules vary from one town to the next in the Coastal Bend.
Will my electrical panel handle a charger, or do I need an upgrade?
It depends on your panel's size and how much spare capacity it has. Older or smaller panels may already be near their limit, and adding a charger could require a subpanel or a main panel upgrade. A good electrician does a load calculation first to tell you whether your panel is ready or needs work.
Can the charger be installed outside for a driveway or carport?
Yes. Many homes in South Texas park outside, and chargers can be mounted on an exterior wall or post. Outdoor installs use weatherproof equipment and covers, and most charging units are rated for outdoor use. Let the electrician know where you park so the run and the enclosure are set up for the weather and heat.
Should I get a hardwired charger or a plug-in one?
Both work. A plug-in unit connects to an outlet like a NEMA 14-50 and is easier to swap or take with you. A hardwired unit is wired directly to the circuit, which some people prefer for outdoor spots or for higher-power charging. Your electrician can explain which fits your car, your parking spot, and your panel.
How long does a typical install take?
A straightforward home install where the panel is near the parking spot often takes a few hours to a day. Longer wire runs, outdoor installs, or a panel upgrade take more time, and waiting on a permit or inspection can stretch it out. Ask for a time estimate after the electrician sees the site.
Can a business or fleet get multiple chargers installed?
Yes. Shops, offices, and fleet yards often add several charging stations at once. That usually involves a bigger power supply, load management so the chargers share available capacity, and sometimes a service upgrade. It is worth planning for future vehicles up front so the wiring supports adding more later.
