"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

If you connect the wrong electrical wires together, it can lead to a very dangerous electrical shock. All wires should be matched with wires of the same color. It’s very important to consult an electrician if you’re unsure about how to wire your fixture.

To avoid drilling into wire, you will need to trace your home's wiring using a stud finder, wire detector, circuit tracer, or voltage finder. Since locating wires in your home can be difficult for some homeowners, hire a professional electrician with the experience and knowledge needed to safely handle electrical systems before drilling into any walls in your home.

Yes, an AFCI (arc fault circuit interrupter) outlet also has line and load terminals, although it uses different technology than a GFCI and offers a different kind of protection. AFCIs monitor for internal arc faults, a type of wiring problem that can start an electrical fire.

How far you can run underground electric depends on the wire gauge (generally AWG) and the circuit voltage. Too much voltage drop in an electrical circuit can negatively affect performance, so the smaller the voltage drop, the better. Ideally, it shouldn't exceed 3%. The smaller the wire and the longer the run, the more significant the voltage drop. 

For example, with a 120-volt circuit, you can run 60 feet of 12 AWG cable without losing more than 3% voltage. With a 240-volt circuit, you can run 120 feet of 12 AWG wire while maintaining a voltage drop of 3% or less.

To determine if an electrical outlet is blown, look for visible signs of damage such as a burning or smoky smell, burn marks, or a melted or discolored plastic cover. If you notice a burning smell, contact an electrician immediately. Other signs include a plug that keeps falling out or the outlet not working when you test it with different devices. For further troubleshooting, you can use a voltage tester or multimeter to check for power; a reading of zero indicates a problem. Also, check your circuit breaker or fuse box to see if the circuit was tripped and reset it if necessary. If these steps don't resolve the issue, the outlet may need to be replaced.
