As homes add EV chargers, heat pumps, and more electronics, the old 100-amp panel is often no longer enough. Here’s how to know if a 200-amp upgrade is right for you.
What amperage do you have now?
Check the main breaker in your panel — the number on it (100, 150, 200) is your service size. Many older Fremont homes have 100-amp service, which can struggle with modern demand.
Signs you need more capacity
- Breakers trip when multiple appliances run
- You’re adding an EV charger, hot tub, or AC
- You’re remodeling or adding a room
- Your panel is full — no space for new circuits
- You still have a fuse box
Why 200 amps?
A 200-amp panel gives you room to grow: EVs, electric ranges, heat pumps, and future upgrades without nuisance tripping. It’s the modern standard for most single-family homes.
Is it worth it?
For most homeowners planning to stay — or add major electrical loads — yes. Beyond convenience, a modern panel is safer and can add value at resale.
