Fuse Box to Breaker Panel Conversion Cost in Ontario

If your insurer flagged a fuse panel or a Federal Pioneer Stab-Lok panel, a conversion is usually the fastest way to clear the file. Here is the real cost.

For the service itself, see Fuse Box to Breaker Conversions in Toronto & the GTA.

Typical Tron pricing

• **Fuse box to breaker panel conversion — $2,500 to $3,500**
• 100 amp panel replacement — $2,000 to $3,500
• 100 amp to 200 amp service upgrade — $3,500 to $5,000+

Pricing includes the ESA permit and inspection coordination plus the Hydro disconnect and reconnect. Overhead services can cost more when the mast, weatherhead, conductors, meter base or attachment point need replacing.

Why insurers ask for it

Most Ontario insurers now surcharge or refuse to renew coverage on fuse panels, 60 amp service, and recalled Stab-Lok panels. Fuses protect wire, not people, and Stab-Lok breakers have a documented history of failing to trip. A modern Eaton, Siemens or Square D panel with an ESA certificate typically clears the requirement immediately.

How long the power is off

A typical conversion is a single-day job. Power is off only for the cutover window, usually four to six hours, because we book the Hydro disconnect and the ESA inspection in advance.

Signs you should not wait

• Screw-in fuses or 60 amp service
• Warm or discoloured panel cover
• Repeated blown fuses
• Insurance non-renewal or surcharge
• No safe way to add an EV charger, heat pump or induction range
