"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

GFCI outlets should be clearly labeled with LINE and LOAD labels, with arrows leading to the proper terminals. The line terminals are typically at the top, and the load terminals are typically at the bottom.

The color of your cable will help you to identify its function. In the U.S., the National Electrical Code (NEC) designates the color code for electrical cables. “Hot” cables are black, red, and blue. In cases of higher voltage lines, orange might also be used to indicate a hot cable. White or gray indicates a neutral, and green or green with a yellow stripe indicates a ground.

You can identify Federal Pacific Stab-Lok® breakers by the label on the front of the panel that says “Federal Pacific” or “FPE” and the breaker itself should say “Stab-Lok®” either on the face of the panel or a label inside the panel door. The Stab-Lok® breakers are also usually red on the breaker switch.

The cost of fixing faulty wiring depends on the type of repair required. Replacing an electrical service line, for example, can cost up to $500. Rewiring an entire house will cost at least several thousand dollars. Replacing old wiring like knob and tube wiring will be even more expensive, but fortunately that kind of outdated wiring is fairly rare. Always get an estimate from a reliable electrician to learn the cost details. 

It’s a great idea to replace and update outlets, especially if an outlet stops working. New outlets work well with modern appliances and devices. Over time, outlets become old and worn—they can even become damaged, cracked, and burnt if the wiring is old and outdated. Old outlets and wiring can cause smoke, sparks, flickering lights, and an electrical fire.
