With the increasing popularity of electric vehicles (EVs), many homeowners are considering the installation of electric car chargers in their homes. While this decision is a step towards sustainability and environmental consciousness, it's essential to conduct thorough assessments before installing an electric car charger. One of the crucial assessments involves checking the electrical load of your property. In this blog post, we'll discuss why it's vital to examine your electrical load before installing an EV charger.

1. Understanding Electrical Load: Electrical load refers to the total amount of electricity a property uses at any given time. It's crucial to comprehend your home's electrical load to ensure that it can accommodate the additional demand an EV charger will introduce. An overloaded electrical system can lead to electrical hazards and potential damage to devices and appliances.

Some questions that need to be asked:

- How large is your service?

- What is the square footage of your house? - Do you have a hot tub installed? - Does your house have more than one electric oven or electric clothes dryer (perhaps for an apartment downstairs) - Does your house have any electric heating? - Do you have an electric water heater?

2. Assessing Your Existing Electrical System: Before installing an EV charger, it's essential to evaluate your home's existing electrical system. This evaluation should include an inspection of your main electrical panel, circuit breakers, and the capacity of your service entrance. Understanding the amperage and voltage of your current electrical system is crucial in determining its capability to support the EV charger's requirements.

3. Consulting a Licensed Electrician: In Ontario, the installation of an EV charger must be completed by a Licensed Electrical Conractor. They can assess your electrical system's capacity and recommend any necessary upgrades or modifications, and an electrician will ensure that your electrical system can handle the additional load an EV charger will impose without causing any hazards or overloads.

4. Determining Charger Specifications: Different EV chargers have varying power requirements, ranging from standard Level 1 chargers (which use a standard 120-volt household outlet) to faster Level 2 chargers (requiring a 240-volt electrical circuit). Understanding the specifications of the charger you plan to install is crucial in assessing whether your electrical system can support it.

5. Upgrading Your Electrical System if Needed: Based on the assessment and recommendations of a licensed electrician, you may need to upgrade your electrical panel or service entrance to accommodate the additional load of an EV charger. This upgrade ensures that your electrical system remains safe, reliable, and efficient even with the increased power demand.

6. Ensuring Safety and Compliance: Adhering to safety standards and local building codes is paramount when installing an EV charger. Proper installation, in compliance with regulations, guarantees not only your safety but also the longevity and performance of your EV charger.

7. Conclusion: Installing an electric car charger can be a great way to save on your daily transportation cost. However, before proceeding with the installation, it's crucial to assess your home's electrical load and ensure that your electrical system can support the additional power demand. Consulting a licensed electrician and understanding the specifications of the EV charger are essential steps to guarantee a safe and successful installation. By prioritizing safety and compliance, you can enjoy the benefits of convenient and efficient EV charging at home while maintaining a secure electrical system.
