Your electrical panel is the heart of your home's power. Many homes built before 2000 still run on a 100-amp panel that was never designed for today's appliances — let alone an EV charger. Here's how to tell when it's time for a 200-amp upgrade.
The warning signs
- Breakers trip often when you run the microwave, AC, and dryer together.
- Lights flicker or dim when large appliances kick on.
- You still have a 100-amp panel (check the main breaker's number).
- You rely on power strips because outlets are scarce.
- Fuses, not breakers — a sign of very old service.
- Warm panel or burning smell — call an electrician promptly.
- You're adding a big load like an EV charger, hot tub, or addition.
What a panel upgrade includes
A 200-amp upgrade replaces your main panel and breakers, and coordinates with the utility for the service change. Installs typically start around $2,000 depending on your home's wiring and panel location.
Why it's worth it
Beyond safety, a 200-amp panel future-proofs your home for EVs, heat pumps, and modern appliances — and it's a strong selling point. If two or more signs above sound familiar, it's worth a professional look. Request a free quote and we'll assess your service.
