    Understanding Your Home Electrical Capacity: Do You Need a Service Upgrade?

    Your home electrical capacity determines how much power your system can handle. Here is how to understand it and when an upgrade makes sense.

    Common Service Sizes in Florida Homes

    • 100-amp: Common in older homes. May be insufficient for modern loads.
    • 150-amp: A middle ground. Workable but may be limiting.
    • 200-amp: The current standard. Handles most modern homes.
    • 400-amp: For larger homes with significant demands.

    When to Consider a Service Upgrade

    • You are adding an EV charger, generator, or HVAC system
    • Your breakers trip frequently under normal use
    • Your home has 100-amp service or less
    • You are planning a remodel with new circuits
