Panel upgrades for older homes and growing electrical loads
Fuse boxes, small services and crowded breaker panels struggle with modern loads. Amp Pro replaces and upgrades panels and service entrances, including 100 to 200 amp upgrades, so your home can safely handle what you plug in today and what you add later.
What we do:
- Fuse panel to breaker panel replacement
- 100A to 200A (and larger) service upgrades
- Meter base and service mast work, coordinated with your utility
- Sub-panels for additions, garages and workshops
- Capacity planning for EV chargers, hot tubs, heat pumps and suites
- ESA permit and inspection
When this makes sense
- Fuses that blow, or breakers that trip often
- Lights that dim when large appliances start
- A panel with no spare spaces, or one that runs warm or buzzes
- Adding an EV charger, hot tub, heat pump or suite
- An insurer or home inspector flagged your panel
How it works
- Tell us about the job. Use the quote form or call. Photos of the area or your panel help.
- We review and quote. We look at what you sent and, when needed, visit to see the site.
- Permit and scheduling. We arrange the ESA electrical permit and book a date that works for you.
- Install and inspection. We do the work to the Ontario Electrical Safety Code and the ESA inspection follows.
Common questions
- Do I need a permit for a panel upgrade?
Yes. Panel and service upgrades in Ontario need an ESA electrical permit and inspection. We take care of that as part of the job.
- How do I know if I need 200 amps?
It depends on what your home runs now and what you plan to add, such as an EV charger, hot tub, heat pump or basement suite. We size it properly when we quote.
- Will the power be off during the upgrade?
Yes, for part of the job. We plan the shutdown with you ahead of time so you know what to expect.
