In today’s blog, our expert electricians will go over how electric vehicle charging affects your panel, signs an upgrade is needed, and our panel upgrade and charger installation processes.

While Alberta still has some catching up to do in regards to EV ownership, we’re starting to see quite a few pop up in Calgary and the surrounding areas. And as a result, EV charger installation is becoming more popular than ever, as home and business owners are looking for the most powerful and efficient charging options to keep their EVs on the road.
In order for your charger to work its magic, there is also the chance that your electrical panel will need to be updated in order for your system to handle the increased load.
Enter 4-Star Electric! In today’s blog, our expert electricians will go over how electric vehicle charging affects your panel, signs an upgrade is needed, and our panel upgrade and charger installation processes.
Our team has been leading the way in electric installation, repair, maintenance and innovation for over 35 years. Let’s begin!
How EV Chargers Work & How They Effect Your Electrical Panel
EV chargers come in three distinct types:

Level 1 - Standard Outlet
A Level 1 charger is just a fancy way of referring to the standard outlet power supply you already have in your home or business. These chargers will charge your vehicle, however it will take significantly longer because of its limited capacity. Most EV drivers will have to leave their vehicles charging for long periods of time, like overnight, to get a decent mileage out of their vehicle.
Level 2 - 240V
Level 2 chargers are the most widely recommended option for homeowners in Calgary and beyond. They’re more powerful and can typically charge a medium-sized electric vehicle within 3-8 hours.
Level 3 - DC Commercial Grade Charger
DC chargers are the big charging stations you see in your grocery store parking lots or along rest stops on the highway. They involve multiple system upgrades and special permits, so you won’t usually see these in residential applications.
How Chargers Effect Your Panel
Most standard electrical panels installed in Calgary are 100 amps. Amps represent the measurement of electrical current. Our electricians typically use a ampmeter to gauge these levels, allowing them to determine the amount of electricity moving through a wire at a specific time. The amperage rating of an electrical panel indicates its maximum capacity for managing electrical current.
If you decide on a Level 1 charger, your current electrical panel should be able to handle the load just fine. But if you’re going Level 2 or higher, the required amperage is more than likely enough to max it out.
Having a panel with an insufficient power supply could result in tripped circuit breakers, overheating and damage to not only the panel itself, but any of your connected appliances and devices. Including that charger you just installed.
To prevent these risks we always begin our service with a comprehensive evaluation, more on that below!
Signs Your Panel Needs An Upgrade
Like we mentioned above, if your current panel is only rated for 100 amps, or if it’s over 25 years old, an upgrade might be needed in order to install your new EV charger or we might be able to install a load management device
If you don’t upgrade your panel first, signs of problems will start to pop up pretty quickly, including:
- Flickering lights
- Power outages
- Sparking or smoking
- A panel that’s warm to the touch
All of these issues increase your risk for electrical fires, so it’s best to always consult with one of our electricians when considering an at-home EV charger.
4-Star Electric is also the home of Calgary’s most trusted electrical inspection. Our inspections protect safety and liability and are one of the best ways to protect your EV charger, electrical panel and electrical system as a whole.
We’ll also pull any required permits and sign off on any major electrical renovation (like charger installation) so your project can get going sooner.
Benefits Of Upgrading Your Panel Before EV Charger Installation
The major benefits of panel upgrades are the ability to future proof your home, improve electrical safety and potentially lower your energy costs.
By upgrading your panel before EV charger installation, or any major electrical undertaking, ensures reliable power for years to come.
What To Expect When You Choose 4-Star Electric
EV charger installation, and electrical panel upgrades, are both things that only a licensed, experienced electrician should take on. And is key to ensuring safety and compliance.
Here’s what you can expect when you call in the experts at 4-Star Electric.
Evaluation
Each installation or upgrade starts with an assessment. A licensed electrician will carefully evaluate your home's electrical system and identify suitable spots for installing the charger.
They will conduct a load analysis to determine whether your electrical panel can handle the added demand of an EV charger. This process includes examining your household's overall energy usage and the specific requirements of the charging equipment.
Lastly, your electrician will review local codes and permitting regulations to ensure the installation complies with all safety and legal standards.
Recommendation
Your electrician will suggest appropriate options, like a Level 1 or Level 2 charger, tailored to your specific requirements.
Should your current electrical panel lack the capacity for the charger, we’ll suggest an upgrade, adding a sub-panel, or installing a load management system to handle the increased demand.
You’ll also receive a comprehensive estimate outlining costs and timelines, helping you plan for the installation process.
Installation
The installation process begins with preparing the designated area by selecting the optimal equipment location, ensuring proper access for electrical connections, and organizing the necessary tools and materials.
Your electrician will then install the charger or your new panel in the chosen spot, adhering to all manufacturer specifications and guidelines.
Once the installation is complete, they will conduct a thorough test to confirm the equipment is functioning correctly. They may also recommend scheduling routine inspections to maintain optimal performance and ensure long-term safety.
Finally, the workspace will be cleaned, and any debris or old materials will be removed. With our expert team, you can trust that only reliable, high-quality equipment is installed, backed by industry-leading repair and replacement warranties and a 100% satisfaction guarantee.
In conclusion, if you’re an EV driver, you need a powerful and efficient way to get around town! And installing a new EV specific charger and ensuring you have the panel to match are the perfect first steps.
