EV Charger Electrical Requirements (Canada)
Level 2 EV supply equipment is a major load on residential services. Rule 8-200(1)(a)(vi) addresses EV charging equipment in dwelling load calculations. Run a full service check with the residential load calculator.
Load calculation
Include nameplate or circuit rating for the EVSE in the Rule 8-200 itemized load. EV energy management systems (EVEMS) may affect how load counts when qualified equipment limits current—verify current CE Code and utility requirements.
Panel upgrades
Many 100 A services cannot add a 40 A or 48 A EV circuit without exceeding calculated demand. 200 A upgrades are common for electrification retrofits. Size new feeders with the conductor sizing calculator.
