We guarantee that all materials used will be as specified and up to the code in your area. And, we guarantee to protect the condition of your home.

What Is a Main Electrical Panel?

As you add electrical appliances and circuits, you increase the demand on your power panel. Depending on when your home was built and how much electricity you use, your power panel may need to be replaced or a sub-panel added to keep up with demand.

All of the power for your home comes through this panel from the utility company, to the exit wires that split off and service different parts of the house. These exit wires are called branch circuits or branch wire circuits. Service wire lugs connect the power from the utility through the electric meter to the electrical panel, and are highly dangerous points that should never be touched. The main electrical panel is the central distribution point for all branch circuits of the house.

Branch circuits are connected to the service panel via circuit breakers. The circuit breakers have no purpose other than safety, since they immediately cut off electricity to branch circuits in the event of overload. You can access these circuit breakers and turn them on and off to restrict power to a particular circuit in your home.

The service wire lugs connect the power from the utility to your home and contain intense, concentrated power. It is impossible to turn off the power to the service wire lugs. Main service is continually on, except in the event of an overall power failure, or if you make a special request with the utility company to shut off power from the street.

Unlike branch wire circuits, which are just a portion of the entire electrical service to the house, the service wire lugs represent every single amount of electricity coming into the house. If your home has a screw-in fuse panel, an obsolete panel, or even worse, has lost its UL listing due to a faulty main breaker or circuit breaker—you may have to consider a new electrical panel for your home. Installing a new electrical panel in your home will increase your safety and peace of mind knowing that the heart of your electrical system is working properly for you and your home.

Components of main electrical panels include; the housing unit, panel door, circuit breakers, hot bus bars, neutral bar, ground wire and a ground bar. Changing out or upgrading your electrical service is a job for an experienced electrician.

I had an emergency issue that required me to call an electrician rather than someone I knew. So I decided to find an electric company online that I thought would come by after hours (about 6:30PM) and let me just say, thank you Lord for having me call Mr. Sparky first. From the moment I got Autumn on the phone to having Stephen Uresti come out to the chaos I was dealing with, my experience was nothing short of amazing. I lost half the power going to my house not realizing the extent of how bad the situation was and Stephen made me feel at ease with getting everything fixed. I had to replace my main panel box outside as well as my inside panel box which was all an absolute disaster. Stephen was very communicative with me and helped me navigate my way through such a terrifying time and needless to say a huge financial decision. (Which was 100000% worth it) Not only did I receive excellent customer service from him but the meticulous work him and the guys did was 5 star. Stephen made sure my house was safe in the end and I can’t forget Robert Stewart and Tommy who did such an amazing job getting my panel boxes in and the beautiful workmanship they performed. Mr. Sparky, Stephen and crew, has not only saved my family and home, but restored my faith in humanity that there really are companies that care about people not just their pocket books. I’m proud to say I had work done by Mr. Sparky and will always call them first and recommend to anyone needing electrical work done in and on their home. What a fantastic crew I received who took care of me in such stressful traumatic time. 10/10 would recommend.

We were having issues with the breaker in our home. I called Mister Sparky and they sent someone out right away. Benjamin Buck did a great job with the installation and explaining what the issues were. He also took time to explain what my options were as a consumer. The installation itself was quick, hassle-free, and clear of any post-installation mess. I'm satisfied with the job Benjamin did, and I highly recommend Mister Sparky.

We definitely recommend Frank and 'Mister Sparky' and will continue to use their electrical services in the future.

Roberto R could not have done a better job first, he explained every step and made sure we understood why we were having problems and second, all the options available and what each option included. He never pressured us for any particular option and answered our questions about each option and our safety. He was extremely professional and approachable. Our trust factor was at high levels and knew everything would be done the absolute correct way. We highly recommend Mr Sparky for any electrical questions and repair work you may have.
