Electrical Subpanel Services

What Is an Electrical Subpanel?

An electrical subpanel is an extension of the electrical services from the main electrical panel. These are useful when you need a large amount of energy—especially in the basement, garage, or other workshops. Many families install an electrical subpanel when they are adding in a new appliance, such as yard equipment, a hot tub, or other large devices. If you need to add a new circuit to an existing electrical panel, but you don’t have any more space, you may need to add an electrical subpanel.

At Mister Sparky®, we are dedicated to providing reliable electrical services to homeowners and families across the nation. Electrical issues aren’t only a nuisance to your family; they are also a hazard. If you need your electrical subpanel to be repaired, replaced, or you need one installed, our team is here to help you. Our electricians are highly trained, licensed, and skilled to handle any electrical project, no matter how big or small.

Reliable Electrical Subpanel Installation Services

Adding an electrical subpanel is a good alternative to getting a larger electrical panel. An electrical sub panel device doesn’t add more electrical power to your home. However, it does give you more efficient and easy-to-manage electrical services running from the main panel to other areas of your home. If you think that you might need an electrical subpanel, but you aren’t sure, our team can inspect your situation and can help you find the best solution for you.

We care about you, your home, and your safety. For your peace of mind, our technicians are background-checked and drug-tested. We also provide you with 100% satisfaction guaranteed—so you can rest assured that we will get the job done right the first time.

Types of Electrical Subpanels

Electrical subpanels, also known as distribution panels or load centers, are secondary panels that receive power from the main electrical service panel and distribute it to various circuits within a building. They play a crucial role in organizing and managing the electrical wiring in residential, commercial, and industrial settings.

Here are some common types of electrical subpanels:

Main Lug Only (MLO) Subpanel
Main Breaker Subpanel
Load Center
Flush Mount Subpanel
Surface Mount Subpanel
Indoor and Outdoor Subpanels
Three-Phase Subpanel
Specialty Subpanels

My experience with The Mister Sparky team was great. I had an urgent issue with my outdoor panel following an home inspection and Timothy was on scene a couple of hours later. He took diagnostics and made sure all my questions were answered. The second day Keith and Matthew arrived and worked together to resolve issues in both our house panels. They were both professional and responsive and took their time afterwards to review their work with me.

We had an emergency situation or subpanel was going out causing the outside breaker to get up to 150 They answered my phone call and they sent Roberto out here who helped us get the stuff we need and the pricing just right and then the journeyman came and installed it all. which they also did an amazing job. Everyone quit this company was amazing and we thank you very much from the bottom of our heart

Excellent service and installation of a severely worn out sub panel and checking our oven that caught fire recently. Timothy, Matthew and his helper (sorry forgot your name) were respectful and professional. Very clean work. Also added a surge protector to the main panel. Thank you, well worth the investment.

- Ron Heredia

I called Mister Sparky to install two pendant lights in my kitchen. Richard Cummings Jr. was my electrician and he did an amazing job. He was efficient, courteous, and extremely knowledgeable. Within minutes, I could tell that I had called the right company. I am very satisfied with my experience, and I would recommend Mr. Cummings and Mister Sparky to anyone. I will definitely be a repeat customer.

- Julie Healy

I recently had Mister Sparky San Antonio replace my outside breaker panel and the sub panel located in my garage, and I couldn’t be more impressed or pleased. Matt and Keith worked together seamlessly and exceeded all my expectations. They were not only highly knowledgeable and professional, but also incredibly friendly—I felt like I had known them for years by the end of the day. What stood out most was how they handled unexpected issues in real time, taking the time to explain everything clearly so I understood exactly what was happening. They even went above and beyond their original scope of work—replacing a ceiling fan with a burned-out motor and fixing an improperly installed outdoor light from a previous contractor. It was a truly great experience from start to finish. I wouldn’t hesitate to call on them again for future electrical needs. Highly recommended!
