Electrical Panel Upgrade in Mississauga
Check available electrical capacity before adding a charger at your Mississauga home. A full panel or 100-amp service does not automatically mean an upgrade; the contractor compares current limiting, approved load management and service work.
A load calculation is needed before an upgrade is recommended, so the decision reflects the available service capacity. Sometimes there's room and no upgrade is needed. When the numbers say otherwise, your contractor should upgrade the service, usually to 200 amps, so your charger and your home's other loads run safely without tripping breakers.
A panel upgrade is more involved than a standard charger install and coordinates with Alectra Utilities for the service change and reconnection. Your contractor should handle that coordination, pull the permit, and book the ESA inspection, then install your charger on the new panel in the same visit where possible.
The service change itself is less dramatic than it sounds. Alectra Utilities disconnects and later reconnects the service while the panel is changed by the electrical contractor and any meter equipment, and the duration of the interruption must be confirmed with the utility. Your contractor should schedule around your household so the fridge and the home office are back on before the evening.
Opening an older panel also tends to surface small surprises, doubled-up breakers, unlabelled circuits, the occasional relic from a past renovation, and your contractor should tidy what your contractor should find as part of the work. You finish with a 200-amp panel that carries the charger, the AC, and whatever comes next, plus an ESA inspection that documents the whole job for insurance and for resale. If the meter base or mast also needs attention, your contractor should tell you before the quote, not during the job.
A timer or app schedule controls when charging starts. It is different from an approved EV energy management system that monitors household demand. A Licensed Electrical Contractor confirms capacity, any required monitoring equipment and the allowed charging current.
