Electrical Panel Upgrade Experts Since 1972
Tron Electrical & Automation is an ESA Licensed electrical contractor upgrading electrical panels and services across Toronto and the GTA. We replace 100A services with 200A services, replace and relocate breaker panels, convert fuse boxes to breaker panels, replace meter bases and service equipment, perform electrical load calculations, and handle Hydro coordination and ESA inspections from permit to certificate.
Homeowners come to us when the existing service can no longer carry what the house needs — EV charging, hot tubs, pools, heat pumps, renovations, additions and general high electrical demand. We size the service to what you actually plan to run, not just to what is there today.
100A to 200A Electrical Service Upgrades
A 100A to 200A service upgrade replaces the incoming service conductors, meter base, main breaker and panel so your home has the capacity for modern loads. It is the upgrade most Toronto and GTA homes need before adding an EV charger, a heat pump, a hot tub or pool equipment, or before a major renovation or addition. The physical installation is typically completed in one day, with Hydro scheduling and the ESA inspection booked around it.
Electrical Panel Replacement
Panel replacement addresses the distribution equipment itself: panels that are full with no breaker space, damaged or corroded panels, obsolete panels that no longer accept available breakers, and panels being relocated during a renovation. Where the incoming service is already adequate, a panel replacement can solve the problem without a full service upgrade — and we will tell you which one your home actually needs. Federal Pioneer Stab-Lok panels are unsafe and insurers refuse them — we replace them in one day.
Fuse Box to Breaker Panel Conversion
Older Toronto homes still running on fuses can be converted to a modern breaker panel. Conversions frequently come up during insurance reviews, home purchases and renovations, and are usually paired with a service upgrade because the existing service is also undersized.
Electrical Load Calculations
Every upgrade begins with a load calculation: existing heating and cooling, range, dryer, water heating and general lighting and receptacle load, plus whatever you plan to add. The calculation determines the service size you need and whether a panel change alone is sufficient — it is also what the ESA inspection is measured against.
Hydro & ESA Coordination
Service upgrades require utility involvement and an ESA permit. We file the permit, coordinate the disconnect and reconnect with the local utility, complete the work to code, and see the ESA inspection through to the certificate you need for insurance and resale. We maintain a 99% ESA first-pass rate.
