Home EV Charging Install

Please note: Depending on the actual distance from the panel and access, cost is subject
to the amount of wire needed. Also, each city has its own permitting costs and inspection
requirements that may affect the total cost. Drywall patch and paint is not covered in our
estimate and would be done by others.

Is your electrical panel in the garage?

Where would you like the TWC/NEMA 14-50 installed? Right next to the panel or in another location?

Is there attic access directly over the garage?

Do you know if you want the NEMA 14-50 for the Tesla Mobile Connector? Or, will you be purchasing the Tesla Wall Connector (TWC)? Or any Other helpful information

Installing an Electric Vehicle (EV) charging station in your home in McKinney or Collin County requires not just technical know-how but also a thorough understanding of local regulations to ensure safety, compliance, and efficiency. ABR Electric, a professional installation service, emphasizes the importance of obtaining the necessary permits and undergoing inspections for these installations. Here’s why:

Electrical Capacity Concerns: Many homes may not initially have the electrical infrastructure to support the added load of an EV charging station. Identifying this early through a professional assessment can prevent the need for expensive electrical upgrades later on.

Code Compliance: Ensuring your installation complies with the latest building and electrical codes is crucial. As of January 1, 2023, McKinney City Council has adopted several new codes, including the 2023 National Electrical Code by the NFPA, effective September 1, 2023. These codes are designed to ensure the safety and efficiency of electrical installations.

Permit Delays: The permit process can be detailed and time-consuming. However, obtaining a permit is essential as it ensures that your installation will be reviewed and approved as meeting local standards.

Inspection Backlog: Due to the increasing popularity of EVs, there might be a backlog in inspection requests. Inspections are vital to ensure that the installation has been done correctly and safely.

Utility Coordination: Installing an EV charging station may require coordination with local utility providers. This process can sometimes be complex and requires professional assistance to ensure that all necessary steps are taken.

Ventilation Requirements: Some charging stations, especially those installed indoors, may require adequate ventilation to prevent overheating and ensure safety. Compliance with local codes, including ventilation requirements, is mandatory.

Current Adopted Codes and Their Impact on EV Charging Installation

McKinney’s adoption of the 2021 International Codes and the 2023 National Electrical Code introduces specific regulations and amendments relevant to EV charging installations. Homeowners and installers must be aware of:

Special regulations outlined in the Unified Development Code (UDC), including setback requirements, height measurements, parking, screening, and more, which could affect where and how EV charging stations are installed.
Requirements for accessory uses, landscaping, tree preservation, and architectural standards that may influence the placement and appearance of outdoor charging stations.
Regulations on exterior lighting, construction, electrical installations, and fencing that ensure the safety and aesthetics of the installation area.

Choosing between a NEMA 14-50 outlet and a Tesla Wall Connector for charging your Tesla involves understanding the key differences and considering your charging needs, convenience, and future plans. Here's a breakdown to help you decide:

NEMA 14-50 Outlet
Flexibility: The NEMA 14-50 is a standard electrical outlet for high-power appliances. It offers flexibility because you can use it with the mobile connector that comes with your Tesla, as well as other devices that require a 240-volt power source.
Charging Speed: Provides up to 29 miles of range per hour of charge for most Tesla models. While this is adequate for overnight charging, it's slower than the Tesla Wall Connector.
Installation Cost: Generally, installing a NEMA 14-50 outlet is less expensive than a Tesla Wall Connector because it's a simpler and more universal outlet.
Portability: If you move frequently or want to use the outlet for other purposes, a NEMA 14-50 offers the advantage of versatility and portability.
Tesla Wall Connector
Charging Speed: Offers faster charging speeds, up to 44 miles of range per hour of charge, depending on your Tesla model and the electrical capacity of your home. This is significantly faster than what you'd get from a NEMA 14-50 outlet.
Convenience: Designed specifically for Tesla vehicles, it provides a seamless and integrated charging experience. It's permanently mounted to the wall, offering a dedicated charging solution that's always ready.
Smart Charging Features: The Tesla Wall Connector supports load sharing and can be connected to Wi-Fi for firmware updates, making it a more future-proof choice. This is particularly useful if you plan to add more electric vehicles to your household.
Cost: The initial cost is higher than a NEMA 14-50 installation, both for the unit and the installation. However, the faster charging speeds and dedicated design may justify the expense for many users.
Which One Should You Choose?
Consider Your Charging Needs: If you drive long distances daily and need quicker charging, the Tesla Wall Connector is a better choice. For occasional drivers or those with longer dwell times at home, a NEMA 14-50 may suffice.
Future-Proofing: If you plan to stick with Tesla vehicles or want the fastest home charging solution, investing in a Tesla Wall Connector might be wise.
Budget and Flexibility: If you're looking for a more cost-effective and flexible solution, especially if you rent your home or might move in the near future, a NEMA 14-50 outlet is a great choice.
Ultimately, the decision should be based on your specific charging needs, budget, and plans for the future. Both options provide a reliable home charging solution for Tesla vehicles, so consider what's most important to you in making your choice.

Why is a permit and inspection necessary?

In order for you to modify the electrical panel of a home a permit and inspection from your local building department is required. These requirements are designed to ensure safe and code compliant electrical installations for both yourself and your neighbors. The permit will also make local utilities aware of growing electric vehicle ownership in the area, allowing ample time to plan ahead for any infrastructure upgrades for the community.


When should I install home charging?
We recommend installing home charging shortly after ordering your Tesla vehicle. Some installations, such as detached garages or electrical system upgrades, will require longer lead times. Installing the electrical equipment ahead of time will ensure you are prepared to charge at home when taking delivery of your vehicle.

How much does it cost to install charging equipment?​

Depending on the scope of work.

Some minor drywall removal is required when running new wiring to the side of the panel. Depending on what city you are in there may be added cost for permit and inspection fees.

Cities like McKinney and Frisco require a licensed electrician to be onsite for the electrical inspection. The permit and inspection fees, for cities that require an electrician to be onsite, are set by the city.

It’s important to note that every installation is custom to the home. Depending on your length of wire run and other modifications that cost might add up.

Distance is an important factor; an installation which is 100 feet away from the electrical panel will be more expensive than an installation 10 feet away.

Some homes may need a utility upgrade. Plan ahead if you have a more complicated installation, such as trenching to a detached garage.
