"J&M Electrical did an outstanding job of installing a home backup generator. When the gentleman came out to do the onsite inspection and provide me with the results and options, it was a no pressure sales approach. He walked me through the entire process that was used to determine what size generator I would require in the event of a power failure. When he had left the house that evening it was not with an ultimatum of “You must let us know right away, or in the next 72 hours” type approach. In this case it was more along the lines of “Think it over and we are glad to have been able to present our product” Once we decided to have the generator installed the communication from the front office in regards to what was required from me and what the contractor would provide was excellent. Scheduling was easy and all that was discussed was provided on time and with no exceptions. The work crew was on time and cleaned up upon completion of the installation. Overall an outstanding experience and I would recommend them to anybody looking to have a backup home generator installed."

"After a lightning surge caused electrical issues in our house, Your Electric Solutions scheduled us much faster than other companies. Bill was fantastic! He troubleshot the issues, installed a surge protector, inspected our outlets, and replaced damaged ones. His work was neat, his prices were very reasonable compared to competitors, and he patiently answered every single question without making me feel silly. Highly professional. I’ll definitely hire them again!"

"Tolliver Electrical did a commercial job for me at Fleetpride. (a heavy duty truck parts store) The company did an excellent job in completing the electrical work before the staff reported back to work the following morning. Tolliver Electrical is the only electrical company that I call on for all my electrical needs"

Electrical questions, answered by experts

Switching the hot and neutral wires in an outlet or receptacle, a condition known as reverse polarity, is dangerous. While the outlet will still function and provide power, it creates a significant electrical shock hazard because anything plugged into it will remain electrified even when switched off. If you touch a conductive part of the appliance, such as the metal components of a toaster, you could receive an electric shock.

The National Electrical Codebook indicates that there should be at least 6 inches of wiring in the breaker box for connecting purposes. When in doubt, err on the side more, because you can always cut some wire off but you can never add it back on, and if you don’t have enough you may struggle to finish wiring your breaker box properly.

Single switch installs are quick DIY projects, but you should consider enlisting the help of a pro for more complicated replacements—like a smart switch or if you live in an older home with outdated wiring. Professional electricians are trained in the latest code regulations. They are also insured, licensed, and bonded.

While you might not need to put lights and outlets on separate circuits, some local codes may require that you use separate circuits. Installing a separate circuit helps prevent total darkness in your home when your receptacle outlets take on too much power and blow a fuse or trip the breaker. It also costs less and is easier to simply install a new circuit.

They’ll use more electricity than the average upright vacuum, but not remarkably more. Most power units plug into a standard 120-volt outlet and don’t have significant power demands. You shouldn’t notice an increase in electricity bills. If you have any specific questions about energy costs, ask your installer as you examine purchase decisions. Larger power units will need more electricity for their suction levels.
