As EVs become an increasingly popular choice for Calgary’s eco-conscious drivers, the convenience of charging at home is becoming less of a convenience, and more of a necessity.
But before you plug in let our experienced electricians go over how EV chargers could affect your home electrical systems. From your panel to your infrastructure, we’ve got you covered. This guide will ensure a seamless transition into the world of at home EV charging.
The 4-Star Electric team is well-versed in everything EV, and we’re Calgary’s preferred choice for installation and system upgrades. We work within your schedule to offer services to both our residential and commercial clients.
We’re about to shed some light on EV charging, read on!
The Basics Of EV Charging
Unlike regular engines, EVs don’t burn fuel, they run by utilizing stored energy in rechargeable batteries. Most EVs have two batteries, one that powers the motor and the other that powers accessories such as lighting.
And in order to keep these batteries fully charged, drivers must take advantage of either public charging stations or at-home chargers.
The Different Types Of EV Chargers
Level 1 – Standard 120V Outlet
A level 1 EV charger is just a standard outlet, located in either your garage or on the outside of your home. These outlets will charge your vehicle, but due to their limited capacity it usually takes longer. We typically recommend leaving your vehicle to charge overnight, or only using these types of outlets for smaller EVs.
Level 2 – 240V Charging Station
Level 2 EV chargers are the most popular choice for Calgary homeowners. This type of charger is more powerful, which is beneficial if your EV is your primary vehicle and you’re driving it daily. It has significantly faster charging, getting you road ready in a number of hours.
DC Fast Charging
DC fast chargers aren’t typically found in residential applications, they are what power the commercial charging stations you’ll find in parking lots or in rest stops by the highway.
While you can technically install it at home, it requires a significant amount of power, multiple system upgrades, permits and approvals, so we don’t usually recommend this to our residential customers.

The Impact of EV Chargers on Your Electrical System
When considering EV charger installation it’s important you’re familiar with your home’s current electrical system capacity.
Most residential homes in the Calgary area have a capacity of 100-200 amps in their electrical panel, which is the volume of electricity flowing through the wires.
If you just plan to utilize a level 1 charger, your current system will be able to handle the load and no panel upgrades should be required. However, if you choose to install a level 2 or above, our team will recommend an interlocking device, panel upgrade or home rewiring to ensure electrical reliability and safety.
Another important consideration is that installing an EV charger will have an impact on your monthly utility bills due to increased usage. If you’re worried about usage costs, opt to stay with a level 1 outlet, and only charge your vehicle when absolutely necessary. Or if choosing a level 2, connect it to smart technology that can monitor usage and alert you when you’ve reached a certain level.
Finally, it’s always a good idea to schedule an electrical assessment from one of our dedicated electricians before any installation, and we’re proud to offer certified electrical inspections in and around the Calgary area.
A certified home inspection is one of the most effective ways to protect your home and family from the risks of electrical fires. Inspections are also often required for insurance purposes when making major upgrades to your home, including EV charger installation. So call us today!

What To Expect
Evaluation
Every EV charger installation service begins with an evaluation. Your personal, licensed electrician will conduct a thorough onsite assessment and inspect your home’s electrical system, as well as potential locations for your charger install.
Your electrician will perform a load analysis to determine if your current electrical panel can support the additional load of an EV charger. This includes evaluating the total household electrical demand and the specifications of your potential equipment.
Finally, your electrician will review local electrical codes and permit requirements to ensure installation will meet all necessary safety and regulatory standards.
Recommendation
Your electrician will then present suitable charger recommendations, such as a Level 1 or Level 2 charger, or a level 3 if you are a commercial client, based on your unique needs.
If your existing electrical panel cannot support the new charger, your electrician may recommend an upgrade, the installation of a sub-panel or a load management device to accommodate the additional load.
Finally a detailed cost and timeline estimate will be provided so you can prepare accordingly for installation.
EV Charger Installation
The installation area is prepared by identifying the specific locations for your charger, ensuring access for electrical connections, and setting up tools and materials. Your electrician will efficiently install the charger in the recommended location, following manufacturer guidelines.
After installation, your electrician will thoroughly test your EV charger to ensure it’s functioning properly.
