To clarify, this installation guide is for residential wall mounted EV Chargers. Also it should be noted that this guide is not a substitute for a professional electrical contractor and it is highly recommended to hire the services of a professional because you are working with electricity

Time To Do the Installation:
Drill, drill bits, screw drivers, drwyall saw, plyers, wire strippers, wire cutters, level, voltage /electrical meter, electrical tape, ladder, wood wholesaw
EV Charger, Cable or conduit with wires, connectors, conduit couplers, electrical panel breaker, penetrox/cable compound, cable or conduit straps, screws, wall anchors
Electrical permit through Technical Safety BC or your city, also BC Hydro rebate application from electrical contractor if one used and proper load calculation based on the latest electrical code.
STEP 1 - Load Calculation
Firstly, before you start the actual installation process, you will need to calculate the existing load on your electrical service. Calculating tools and tables can be found on our other blog called “Selecting and sizing the best EV Charger for your vehicle”. Please follow the link above because this step is definitely important. This step will determine the available load and the size of the EV charger.
STEP 2 - Selecting an EV Charger
Secondly, based on the load calculation above you will need to determine the EV charger that falls within the available load. Additionally, you will also want to look at all the extra features you want and find essential; such as, notifications and remote access. Different types of EV chargers have different charging speeds, different power outputs, and different charging connectors and additional features; therefore, it is important to identify what you want your EV charger to do. More about features on the next step
As an Example , a Level 1 EV charger for a Tesla Model 3 to charge it from 20% to 80% will take 22.5 hours. A Level 2 7.5kW charger for the same vehicle and charging levels will take 7.5 hours.
STEP 3 - Selecting the EV Charger's Features
Furthermore, having additional features available to monitor and control your vehicle charger is an important factor for many homeowners. Because it is part of the home automation initiative and it can give you more control over charging times, you should think of the extra features that are important to you . Each EV charger can offer different features like time delay charging, charging level monitor, hour of day charging & proffered hours to charge, cell phone and smart device interface, connectivity with other smart devices and IFTTT, power quality, etc.
STEP 4 - Finally, Applying for BC Hydro Rebates
Because you want to ensure that you don’t overspend on your installation, you should find out and apply for all available rebates such as BC Hydro and federal rebates. For a limited time BC Hydro offers great rebates for home and networking EV charger. Up to $700 for home installations which covers the EV charger and installation cost. Make sure you follow the instructions on the BC Hydro page or call BC Hydro directly to obtain all forms and paperwork to be summited in order to avoid delays.
STEP 5 - Finally, Purchasing the Charger and Connectors
Well, everything else is set, and so, its time to buy your EV charger. There are many places where you can buy your EV charger but if you don’t feel comfortable with online purchase it is always recommended that you go to a local distributor or contact BaTCO Tech, your local contact point for British Columbia. For instance, BatCO Tech offers a Tesla Gen3 Wall Charger for $680 backed up by a one year warranty.
STEP 6 - Installation Time
Lastly and as important is the installation procedure. We recommend having an electrical contractor do the installation and provide a certificate of completion with attached warranty. This will help when you apply for house insurance and also Hydro rebates. However, if you feel comfortable doing the job, grab your tools and your tool pouch and let get started. This does require a level of skill.
First, you will need to turn power off to the panel. Make sure you test and lock all sources of power before proceeding. Run the cable or conduit from the electrical panel to the location of the EV charger. How you run it will depend on the location , accessibility and distance. Install the cable or conduit directly to the EV charger or to an electrical box, depending on the manufacturers instruction for your particular model. Install the proper size breaker in the panel; assuming that you have already calculated the proper size cable and breaker size you need to use. Please note that properly sizing the cable and breaker is very important. If in doubt do not hesitate to call us. If you are using aluminum wiring you will need to use wiring compound; however you should read the manufacturers requirements as some EV chargers only accept copper. Tighten your wires to the panel bus par and breaker ensuring you make proper bonding and connection.
DISCLAIMER: Because of the many accidents, death and loss of property , I can not stress enough how important it is to hire a professional that not only knows but also is certified to work on your electrical system. Working with electricity if highly dangerous; as a result it has been concluded that 80% of house fires in BC are related to faulty wiring and incorrect electrical installations. Not following electrical regulations and local installation codes will void your house insurance and also put you and your family at risk.
