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

Highly recommend Chris Bevans of Mr. Sparky in Myrtle Beach. Have used him twice now for pendant lights in kitchen and an EV charging station. He is extremely knowledgeable, works fast and clean, and comes when scheduled.

I want to thank Spencer and Jonathan and Mr. Sparky for their outstanding job with installing electrical to my shed. They were neat and clean. I recommend them for all your electrical projects needs. Btw we remembered your commercial👍

- Joe Butler

Great company, happy to work with! Saved me on big project and stayed reliable through all follow ups and inspections. Lane, Jonathan and Nathan are my favorite technicians! And manager is great too!

Jason Reynolds was friendly, prompt, professional, courteous and above all, knowledgeable! He carefully explained my options as I had quite a laundry list that had been building for 3+ years. I was truly impressed with Jason and would give him a 10!!! UPDATE: On July 2, 2025, Jason Reynolds and Jamison Ruppe were able to get started an hour earlier than scheduled. As I said above, my to-do list grew from original estimate to a few items more. Was glad to see he had an extra hand on board to help. My condo was built in 1987...this presenting a few challenges along the way. Even as I added something new or had a change of heart, Jason exceeded my expectations. After all was done, I am thrilled with the projects that needed attention. Jason never once said anything negative. Whenever I might have challenged him, he remained the same professional as he was with the initial visit. I would recommend Jason to any and every person that needs electrical work services. Jamison was a huge help in assisting Jason and doing things on his own. Again, this was an entire afternoon of no drama and no negativity!!! Outstanding service!!! Thanks Jason and Jamison for all of your hard work!!!

I had a great experience with the technician from Mister Sparky who came out to give us an estimate. He was punctual, professional, and took the time to thoroughly explain everything in a clear and honest way. I appreciated how respectful and knowledgeable he was, answering all my questions without rushing. It’s rare to meet someone who combines technical expertise with such great customer service. Highly recommended!
