Installation
Level 2 charger installation at home
Most electric vehicle owners in Canada charge at home, and a Level 2 setup is the usual way to do it. Level 2 refers to charging on a 240-volt circuit, the same class of supply used by an electric range or clothes dryer. Compared with plugging into a standard 120-volt outlet, the higher voltage lets the vehicle replenish range over a few hours rather than across a full day.
How Level 2 differs from a wall outlet
A 120-volt outlet, sometimes called Level 1, works with the cordset that ships with many vehicles and needs no new wiring. It is slow, and it is generally treated as a fallback rather than a primary method. Level 2 equipment connects to a dedicated 240-volt branch circuit and a unit rated for a specific current, commonly in the range of 16 to 48 amps for residential models.
The practical charging speed depends on two limits: the circuit and charger on the wall, and the vehicle's onboard charger. Whichever is lower sets the rate. A high-amperage wall unit will not charge faster than the vehicle's internal hardware allows.
Always check the vehicle's onboard charger rating before buying wall equipment. Paying for a 48-amp unit gives no benefit if the car accepts a lower maximum.
Plug-in versus hardwired
Residential Level 2 chargers come in two mounting styles. Both are common, and the right choice often depends on the install location and local rules.
Plug-in units
These connect to a 240-volt receptacle, frequently a NEMA 14-50, using a plug. The receptacle still needs a proper circuit and breaker, but the charger itself can be unplugged and moved. Some jurisdictions limit the rated current of plug-connected equipment.
Hardwired units
These are wired directly into the branch circuit with no plug. Hardwiring is typical for higher-amperage installations and for outdoor or exposed locations where a sealed connection is preferred.
| Aspect | Plug-in | Hardwired |
|---|---|---|
| Connection | 240-volt receptacle | Direct to circuit |
| Portability | Can be unplugged | Fixed in place |
| Typical use | Lower to mid amperage | Higher amperage, outdoor |
What a permitted install usually includes
A straightforward residential job tends to follow a recognizable sequence. The exact steps vary by home and by the rules in your province or municipality.
- A review of the existing panel and available capacity by a licensed electrician.
- An electrical permit obtained before any permanent wiring begins.
- Installation of a dedicated breaker and conductors sized to the charger's rating.
- Mounting and connection of the charger, indoors or outdoors as rated.
- An inspection by the authority that issued the permit.
Where the garage location matters
The distance between the panel and the parking spot affects conductor length and routing. A long run, a finished wall, or an outdoor section can each add complexity. It is worth confirming where the vehicle's charge port sits, since the charger and cable need to reach it comfortably without strain.
