Service Spotlight: Adding a Subpanel – What You Need to Know

Hi, I’m Paul, owner of Blanusa Electric here in Huntington Beach.

If you’re running out of space in your electrical panel—or planning to add something major like a new EV charger, workshop, or an ADU—you might need a subpanel. Installing a subpanel is one of the smartest ways to safely expand your home's electrical system without replacing the entire main panel.

What Is a Subpanel?

A subpanel is basically a smaller service panel that’s connected to your main electrical panel. It gives you a dedicated space to add new circuits without overloading your existing setup. Think of it as a "branch" that helps organize and manage power to new areas of your home or property.

Common reasons to install a subpanel include:

• Adding an EV charger

• Building a home addition or ADU

• Setting up a garage workshop with heavy-duty equipment

• Expanding outdoor living spaces (pools, spas, patio kitchens)

  
  

Why Add a Subpanel?

Here’s why installing a subpanel makes sense:

• Expand safely without overwhelming your main panel

• Organize power for a specific area (like a workshop or guest house)

• Avoid costly full panel replacements when only expansion is needed

• Prepare for future upgrades like solar, battery storage, or EV charging

  
  

Subpanels also make troubleshooting and maintenance easier since everything in that area is neatly separated.
