"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

No. Do not use a 14-gauge wire on a 20-amp outlet. A certified licensed electrician would know that the National Electrical Code (as per Section 240.4(D) subsection 3) requires 14-gauge wires to be used with a maximum amplitude of 15. Therefore, you should only use 12-gauge wires on 20-amp outlets.

Common signs of faulty electrical wiring include frequent circuit breaker trips, flickering or dimming lights, burning smells near an outlet, buzzing or humming sounds, electrical shocks or tingles when handling outlets of appliances, and hot or discolored outlet switches. If you notice one or more of these signs, hire a licensed electrician for an average cost of $50 to $100 per hour to diagnose and make necessary repairs.

The life expectancy of a home electrical panel is typically around 25 to 40 years. However, this can vary based on usage, maintenance, and technological advancements. Regular inspections by a qualified electrician can help determine the condition and potential need for replacement as your panel ages. Factors like overloading, outdated components, or wear and tear might prompt earlier replacements for safety and efficiency reasons.

You can bury underground electrical wire six inches deep—but only if you use a rigid metal electrical conduit. For rigid, non-metallic conduits, bury the wire at least 12 inches deep. If using an underground feeder cable rated for direct burial, you'll need to place it at least 18 inches deep, as it has no conduit for extra protection.

If you have a garage heater that is 1,500 watts or more, it will need its own breaker. As a good rule of thumb, no appliance should exceed 1,500 watts per outlet for best outcomes. Consult a local garage heating service to determine the power needs for your outdoor or indoor space.
