"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

In most cases, line wires are located at the bottom of a panel or device, while load wires are located at the top. Line wires are generally black, while load wires are typically red or black. To tell for sure, you can use a multimeter or volt pen to test the wire. A live or line wire will always carry a charge, while a load wire will only carry a charge when it’s in use.

Yes, standard dimmer switches should never be used to control a ceiling fan motor. They’re designed for lighting, not motors, and they can cause humming, overheating, or permanent damage. You should only use switches that are specifically labeled for fan speed control.

Single-pole light switches are the most common light switches on the market. Their simple features make them easy to install and use. For more powerful applications that require 30 or 40 amps, you may need to use a double-pole switch. Some homeowners may want multi-way switches like three-way or four-way switches to control a light fixture from opposing ends of the room.

Electric water heaters use a high amount of electricity, so they’re best for homeowners who subsidize their electric bill with solar or who live in an area with inexpensive electricity. For others, gas water heaters versus electric water heaters may be the more cost-effective solution, with the added bonus of heating water quickly and efficiently. No matter which you choose, you can lower your water temperature as low as possible to keep costs down.

Yes, an electrical fire can start even if nothing is plugged into an outlet. While a correctly functioning outlet poses no risk, a fire can be caused by faulty wiring, damaged outlet components, an overloaded circuit, or other electrical problems hidden behind the walls. If you suspect a fault, immediately turn off the circuit breaker and contact a professional electrician to diagnose and repair the issue.
