When undertaking a first-time electric vehicle charger installation project, avoiding common mistakes is crucial to save money and time. With this in mind, working with a reputable electrical repair service is crucial to navigate the process seamlessly and safely, while complying with local codes and regulations. At Mr. Electric, we utilize industry knowledge and extensive expertise to address hidden issues that often impede EV charger installations. Although it may seem straightforward for DIY enthusiasts, taking shortcuts instead of following proven practices can lead to disaster. Let’s explore the common mistakes to avoid during an electric vehicle charger installation project.

Choosing the Wrong Site

When picking the right site for a residential or commercial EV charging station, you first need to prioritize convenience. Most DIY enthusiasts or inexperienced handymen not only choose the wrong site but also don’t consider accessibility and proximity to infrastructure. Licensed electricians in Boulder, CO can evaluate potential sites with adequate electrical infrastructure, such as walls, garages, or parking spots. Additionally, professionals can evaluate and review necessary electrical upgrades to provide an accurate estimate.

Picking the Wrong Charger Level

Another common error most property owners make when installing EV chargers is choosing the wrong charger level. If you have a DIY home improvement project scheduled, leave electrical work to a licensed technician. Professionals often recommend level 2 chargers for residential properties, as level 1 chargers usually cannot meet overnight charging demands. In addition, level 2 chargers can be ideal for commercial settings like restaurants, retailers, parks, and other locations.

Ignoring Local Codes and Regulations

DIYers often avoid the tangle of bureaucratic regulations associated with improvement projects. With that said, neglecting local electric codes and safety regulations can lead to costly fines, safety hazards, and legal action. You can avoid such scenarios by hiring a licensed electrical service provider to handle the installation process and ensure everything is done by the book. This saves you a lot of time researching local laws regarding safety concerns, zoning, and electrical equipment.

Miscalculating Load Capacity

Research shows that one of the most common reasons for improper electric vehicle charger installation is incorrect load calculation. Property owners often underestimate the load capacity that these systems require, leading to inefficiencies, safety hazards, and other devastating scenarios. By partnering with highly trained and certified electricians, you can rest assured that they can accurately estimate your station’s load and determine if the grid is up to the task.

Taking Shortcuts to Save Money

Cost is a major factor in electrical projects, and an electric vehicle charger installation is no exception. With that said, DIYers often cut corners to save money in the long run. Unfortunately, this is a counterproductive approach, since using subpar components and avoiding grounding leads to devastating scenarios that are expensive to fix. Not to mention, violating local codes and safety regulations often causes premature replacements and legal fines, adding to the overall cost. No matter how cautious you are during the installation process, taking shortcuts may not be the best approach.

Neglecting Regular Maintenance

After a successful electric vehicle charger installation, most people assume the system will remain functional throughout. However, routine maintenance is crucial to identify and address minor signs of deterioration before they escalate. In the case of severe damage or age, routine checks can ensure that you act quickly to restore safety and performance. Modern systems often have intricate components that require extensive expertise to diagnose, hence the need to work with a certified technician.
