| Step | What happens | Watch-out |
|---|---|---|
| 1. On-site load calculation | A professional measures available capacity and panel space | Don’t order the charger before this visit |
| 2. Choosing the charging level | Level 2 charging (240 V) for homes; shared solutions in buildings | Charging power compatible with your vehicle |
| 3. Permit and installation | Municipal permit as applicable, dedicated wiring, grounding | Written quote detailing the cable route |
| 4. Final check | Full charge test with the vehicle | Usage instructions and charger warranty |
Start with the installation, not the charger
Many EV owners start by picking a charger online, only to discover their panel has neither the space nor the capacity for it. The right order is reversed: assess the installation first, choose equipment second.
A level 2 home charger adds sustained demand for hours every night. On an already loaded installation (electric heating, dryer, hot tub), that demand may exceed what the current service allows without adjustment. Only an on-site load calculation demonstrates it.
That visit also maps the cable run: distance from panel to parking spot, routing through walls or foundations, indoor versus outdoor. Run length and complexity shape the quote as much as the charger itself.
House, duplex or condo: three different contexts
In a single-family home, the project is straightforward: load calculation, location choice, dedicated wiring to the parking spot. Most installations resolve without major service upgrades.
In a duplex or rental building, the question becomes which meter serves your parking spot. If the spot is fed from a common panel, the owner’s agreement is required; if each unit has its own panel, the project becomes individual again.
In a divided co-ownership, the golden rule is to start with the declaration of co-ownership and the board. Many buildings gradually adopt shared solutions with individual billing; others require formal approval for any new outlet. Starting work without that agreement risks having to undo everything.
Permits, safety and qualified professionals
Depending on municipalities, installing a charger requires a permit and sometimes an inspection. The connection goes onto a dedicated circuit with compliant protection and grounding: these are not optional details, they are the conditions for years of safe charging.
On who does the work: electrical tasks are reserved for people holding the required qualification for their scope. For the dedicated wiring and charger connection, deal with a competent professional (a verified RBQ-licenced contractor where the scope of work requires it), rather than an improvised setup.
Keep the complete file: load calculation, quote, permit, photos of the cable route. This file eases resale, answers insurer questions and supports any warranty discussion with the charger manufacturer.
Cost and owned uncertainty
What budget? There are two components: equipment and labour. The second varies enormously: a few metres of surface cable or thirty metres crossing a foundation tell very different stories. Any amount stated here would be invented; treat the cost as an indicative range to be confirmed on site.
Expect edge cases that change the math: a service upgrade if the load calculation is tight, outdoor trenching, or shared building solutions whose billing depends on local governance.
The honest process fits in three moves: get it assessed, compare two written quotes, then install to code. That is also what protects the genuine resale value of a home charger.

What these numbers do not cover
This guide does not price the installation; panel capacity, distance to the connection and local service requirements set the cost.
