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

We recently had a safety inspection of our home by Ethan with Mr. Sparky and I cannot say enough good things about the experience. Ethan was thorough in his work and explained things clearly. Once the project was complete, everything was cleaned up nicely. I would highly recommend Ethan with Mr. Sparky for anyone needing electrical work done with professionalism and respect for their home.

Muhammad of Mr. Sparky is top notch and very well educated and trained not only in his field of electrical work but also in customer service. He was able to pin point the problem I was having with my outlets and also found some additional issues that were related and he took the time to not only educate me on them but also encouraging me that they weren't emergencies but they could be fixed now but replaced and or updated later down the road for longevity. I was very appreciative for his time and great work I now have the information I was needing in order to move forward with some electrical work and I'm proud to say Mr. Sparky will definitely be doing the work for me and my family. Great business Great owner's Great workers Great customer service A true 5 star experience Thank you again Muhammad and Mr. Sparky

We had a Generac generator installed with a new transfer switch. The project looks great and passed inspection with no problems. The guys worked great together and with me. Highly recommended them!

Jose and Caleb from Mr Sparky came to give us an estimate for a whole house generator. They answered all our questions and informed us about their service. We ordered our generator yesterday. They will install next week. I called my sister about the generator and she bought one as well. It will also be installed next week. Thanks Mr Sparky for providing us with such trustworthy service. 10/28/25 Michael and his team did a great job installing our new generator. He is a hard worker and explained all the details of what we need to know about the generator. 12/16/25 We had to wait to get our Propane tank installed and filled. Once done, notified Mr. Sparky and the next day DJ Bailey came out to make sure our generator is ready for whatever this winter brings us.
