Fuse Boxes Replaced With Modern Breaker Panels

We remove outdated fuse boxes and install modern breaker panels with proper grounding, bonding and labelled circuits — clearing insurance issues and making your home safe for today's electrical loads. ESA permit and inspection included.

The Three Questions Fuse Box Owners Ask Us

“My fuses still work — why replace them?”

Fuses protect wire, not people, and a 60A fuse panel can't carry a modern kitchen, A/C and EV load. Most insurers now surcharge or refuse coverage on fuse panels — the conversion removes both the fire risk and the insurance problem.

“Will my power be off all day?”

A typical fuse box to breaker conversion is a single-day job. Power is off only for the cutover window — usually 4 to 6 hours — and we book the Hydro disconnect and ESA inspection so nothing drags into a second day.

“Do I need the permit and inspection, or can we skip it?”

Every panel change in Ontario legally requires an ESA permit and inspection. We pull the permit under our ECRA/ESA licence, meet the inspector on site, and hand you the certificate your insurer and future buyer will ask for.

Modern Breakers for a Safer, Insurable Home

Fuse boxes and Federal Pioneer Stab-Lok panels were never designed for today's electrical loads. They trip unreliably, fail under fault, and are routinely refused by Ontario home insurers.

Tron Electrical has replaced thousands of GTA fuse boxes and unsafe panels since 1972 — ESA permitted, Hydro coordinated, and finished clean.

Complete coordination from quote to ESA inspection. We handle the full process start to finish — permits, Hydro coordination, installation, and final inspection — so homeowners never have to manage utility steps, paperwork, or inspection scheduling themselves.

Old Fuse Box vs. Tron Electrical Conversion

If your panel shows any of these warning signs, it's time to convert — before it becomes an emergency or an insurance problem.

Request Service or Assessment

Warning Signs

  • Screw-in fuses or 60A service
  • Federal Pioneer Stab-Lok or other unsafe panel brands
  • Frequent blown fuses or warm/discoloured panel cover
  • Difficulty sourcing replacement fuses
  • Insurance refusal, non-renewal or surcharge
  • Can't safely add modern appliances or EV chargers

EV Charger and Load-Capacity Assessment

An EV charger panel upgrade is not always necessary. Homeowners can request an hourly electricity-consumption report from their Hydro utility. We review this information with an electrical load calculation to determine whether:

  • the existing 100A electrical service has sufficient capacity;
  • an EV energy-management system can avoid a service upgrade; or
  • a full 100 amp to 200 amp panel upgrade is required.

A subpanel adds breaker space but does not increase the total electrical capacity available to the home.

We also replace outdated fuse panels, Federal Pioneer and Stab-Lok electrical panels, and coordinate Toronto Hydro disconnect and reconnect requirements, ESA permits and inspections.
