Electric vehicles have moved from niche to mainstream across Greeley, Fort Collins, Windsor, and the broader Denver metro area. Every month, more homeowners take delivery of a new EV and quickly realize that the standard wall outlet in their garage is not going to cut it. Charging speeds matter. Panel capacity matters. Safety matters. The team at Wirezall Electric has installed EV chargers across Northern Colorado for years, and this article shares the essentials every homeowner should understand before scheduling the install.


If you are bringing home a new electric vehicle or planning to in the next few months, read this before you call any electrician. The right preparation saves time, money, and frustration.


Can Your Current Panel Handle an EV Charger?


This is the single most important question, and it is the one most homeowner’s skip. A modern Level 2 EV charger can draw forty to fifty amps continuously while charging. If your panel is already near capacity with the loads it serves today, adding an EV charger without an upgrade can overload the panel and trip breakers constantly, or worse, create a real safety hazard.


A licensed electrician can run a proper load calculation that compares your panel's rated capacity against your actual demand. The calculation considers your service amperage, your existing major appliances, your HVAC system, and the charger you plan to install. The answer tells you whether your panel can support the EV charger as is, whether load management can solve the problem, or whether you need a panel upgrade first.

Level 1 vs Level 2 Charging Explained


Not every EV owner needs the same charger. Understanding the difference between Level 1 and Level 2 charging helps you choose the right option for your driving needs and your home.


Level 1 Charging

Level 1 charging uses a standard 120-volt outlet, the same kind you have in every room of your house. The charging speed is slow, typically adding three to five miles of range per hour. For drivers who use their EV mostly for short local trips and can leave it plugged in overnight every night, Level 1 might be enough. For most Northern Colorado families, it is not.


Level 2 Charging

Level 2 charging uses a 240-volt circuit, the same kind that powers your electric dryer or oven. The charging speed is roughly five to ten times faster than Level 1, typically adding twenty to forty miles of range per hour. A full overnight charge becomes easy. Quick top-offs during the day become practical. For most EV owners, Level 2 is the right choice, and it is the install Wirezall Electric handles most often.


Permit and Code Requirements in Colorado


EV charger installations require a permit in every jurisdiction across Northern Colorado. The permit process ensures the work meets current National Electrical Code requirements, including dedicated circuit installation, proper grounding, GFCI protection in certain locations, and appropriate breaker sizing for continuous loads.


A licensed electrician handles the permit process from start to finish. The permit is pulled before work begins. The installation follows current code. The final inspection is scheduled and passed before the charger goes into regular use. This documentation protects the homeowner if a question ever arises about insurance, home sale, or warranty service on the EV itself.


The Wirezall Electric EV Charger Installation Process


Every Wirezall EV charger install follows a consistent process designed for safety, performance, and homeowner satisfaction.


  • Initial consultation to understand your EV model, charging needs, and garage layout.

  • On-site assessment of your panel capacity and proposed charger location.

  • Load calculation to confirm the panel can handle the new circuit, or to identify upgrades needed.

  • Written estimate that lays out the full scope, materials, labor, and permit fees.

  • Permit pulled with the local jurisdiction.

  • Installation of the dedicated circuit, including conduit, wiring, breaker, and outlet or hardwired connection.

  • Final inspection passed, charger commissioned, and homeowner walkthrough completed.



Watch: Why You Should Not Hire a Bad Electrician



Why a Licensed Electrician Matters: Do Not DIY This


There are many electrical projects where homeowner DIY can work. EV charger installation is not one of them. The reasons are practical and they are serious.


First, EV chargers run continuous high-current loads. Any small wiring mistake, loose connection, or incorrect breaker sizing creates real fire risk. Second, EV charger installations require permits in every Northern Colorado jurisdiction, and most homeowner DIY installs are not legally permitted, which creates insurance and resale problems. Third, EV manufacturers often require professional installation as a condition of vehicle warranty coverage on charging-related issues. Fourth, the cost savings of DIY are usually small once you factor in the materials, the permit fees, the time, and the potential for rework if the install does not pass inspection.


A licensed electrician handles all of this professionally. The work is done right. The permit is pulled. The inspection is passed. The documentation is delivered. The homeowner gets a charger that works safely for the life of the car.
