Do You Need an Electrical Panel Upgrade? Signs to Watch For
Learn the warning signs that your home electrical panel is outdated or overloaded and when an upgrade to 200 amps makes sense.
Your electrical panel is the distribution center for all electricity in your home. When it can not keep up with modern demands, problems follow -- from nuisance breaker trips to genuine safety hazards.
Signs You Need an Upgrade
Your panel is 100 amps or less and you are adding major loads like an EV charger, hot tub, or new HVAC system. Breakers trip frequently, especially when running multiple appliances. You have a fuse box rather than a circuit breaker panel. Your home has aluminum branch wiring. The panel uses Federal Pacific or Zinsco breakers, both known for reliability issues. You want to add circuits but have no empty slots. Lights dim when large appliances start.
What Size Do You Need?
Most modern homes need at least 200 amps. If you are planning multiple high-draw additions like an EV charger, heat pump, and electric range, 400-amp service may be warranted. We calculate your actual and projected load to recommend the right panel size.
What the Upgrade Involves
A panel upgrade typically takes one day and involves replacing the main breaker panel and potentially the meter base, updating the main breaker to the new amperage, transferring existing circuits to the new panel, adding arc-fault and ground-fault protection where required by current code, updating the grounding system, and coordinating a utility disconnect and reconnect if service entrance work is needed.
Cost Factors
A standard 200-amp panel upgrade runs $2,500 to $4,500 in the East Bay. The price varies based on whether the meter base needs replacing, the condition of existing wiring, accessibility of the panel location, and any additional code requirements.
