If your home’s electrical service panel (breaker box) is full and you need more room to add new circuits, installing a subpanel might be the way to go. Subpanels certainly can add convenience and plenty of room for installing new circuits, but your current system must have enough capacity to support a subpanel.

When should you install a subpanel?

Subpanels are usually used to extend the wiring for multiple branch circuits to a specific area of a home or to a building at some distance away from the main panel. A garage, outbuilding, or a room addition might be a place to put a subpanel.

Why have a sub panel installed?

An electrician might add a sub panel to take the load off of the main circuit breaker panel. This can prevent overloading the electrical system and tripping circuit breakers or melting fuses. Sub panels are also used to separate the electrical needs of specific areas.

Is a sub panel necessary?

Sub panels are often installed for safety reasons. If the main panel is so full that wires are a crowded maze, it’s a hazard. But sometimes, they’re installed for convenience. You might find one alongside the main panel, but they can also be installed in a different room or a separate building.
