A subpanel — also called a secondary breaker panel or load center — is a smaller electrical panel connected to your main panel. It acts as a distribution point for a specific area of your property, such as a detached garage, ADU, workshop, or pool equipment.

Instead of running individual circuits all the way back to your main panel from a distant structure, a subpanel receives a single large feed from your main panel and then distributes that power locally — making the electrical system cleaner, safer, and more expandable.

You likely need a subpanel if: your main panel is full, you are adding a new structure, or you need significant power in an area far from your main panel.

🔌 Expands Your Electrical Capacity
A subpanel gives your new structure its own dedicated circuits — without filling up your main panel or requiring expensive long runs for every individual circuit.

🛡 Safer Than Long Individual Runs
Running dozens of individual circuits from a distant main panel creates voltage drop and installation complexity. A subpanel with a single large feed is cleaner, safer, and more code-compliant.

📈 Easily Expandable in the Future
A properly sized subpanel leaves room for future circuits — meaning you can add more lighting, outlets, an EV charger, or workshop equipment later without major electrical work.
