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

Ant and Mark did an excellent job servicing my home today. They came out to give an estimate on my issue with no power to my water heater. They found that the water heater breaker was tripping and not resetting. I provided the breaker and they replaced that for me but they noticed in the laundry room was missing a bushing and the grounding wasn’t up to par along with a loose box. They did a great job of letting me know the issues and provided options for me. I will be recommending to family and friends the great work they completed for me. I now have hot water ; and now a happy customer!

Thank you Luciano for scheduling my mounting quote appointment promptly and efficiently. Kevin showed up and did an amazing job with the inspection he provided for our new home. Kevin was very knowledgeable and really seemed passionate about his work. I appreciate the great service!

- Vanessa Vazquez

Buck was extremely helpful. Replaced a GFCI and diagnosed a larger problem in our house. Explained everything really thoroughly and was really friendly. Enjoyed talking to him and having him in the house. Would absolutely come back to Misty Sparky again based on this experience.

Frank arrived, assessed the situation, and gave me options for what I want completed. He explained all options and once I made the decision, he went to work like a Boss! He was pleasant to talk with and answered all questions completely. What I liked most, he enjoyed doing what he knows how to do. He deserves a bonus! Thank you Frank and staff for getting here as quick as you did to complete an urgent matter. You’re tops in my book. Mr. Sparky will be my first and only call when service is required. OUTSTANDING!

New update 11/7/25- I had Mister Sparky out again for new electrical tasks since my first review. Again very pleased and will continue to call them for my needs. This time I had Matthew and team and it was a big job and they were extremely professional and respectful (and did a great job) Original review: Very pleased- Art was my electrician and he was so kind and professional. He did a great job hanging a very big light fixture on a very tall ceiling.
