Many older Guelph homes still run on 100-amp panels — or worse, Federal Pacific or Zinsco panels that are known fire hazards. Upgrading to 200-amp service is one of the most important electrical investments you can make.
Signs You Need an Upgrade
- Breakers trip frequently under normal loads
- You're adding an EV charger or hot tub
- Your insurer won't cover the current panel
- You have Federal Pacific (Stab-Lok) or Zinsco breakers
Cost in Guelph
A 200-amp panel upgrade typically costs $2,500–$4,500 including ESA permit, labour, and materials.
