"James came out to price install of a box to plug in my portable generator. After we started talking and me asking questions James was able to give me an outstanding price on a whole house Generac generator with panel upgrade and included a whole house surge protector. They ran into additional costs with running the gas line but James kept to his word and honored the original price! The crew were professional and proficient in their work! Marcie was outstanding with communication and explaining any questions I had! I would definitely recommend this company and would use J&M for any future electrical needs!"

"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

The copper wire used in knob and tube wiring systems can last up to 100 years. However, it’s considered a dangerous and outdated wiring method because the cloth, fabric, or rubber insulation sheathing can become brittle and fall apart. Knob and tube wiring systems should be inspected if you’re considering buying a home with this type of wiring, or if you have problems with frequently tripping breakers, a sign that you may need to replace them.

Yes, blue wires can be hot wires in the U.S. However, they are less common in residential properties than red and black hot wires. Blue wires are typically used as traveler wires in three-way and four-way switches, as well as ceiling fans. They allow fixtures to be controlled by multiple switches, like when there are switches at the top and bottom of a staircase for the same light.

Technically, an outdoor outlet can be on the same circuit as an indoor outlet, but it's generally not recommended. Outdoor outlets should ideally be on a dedicated circuit that doesn't share power with other indoor or outdoor outlets. This helps ensure that the outdoor outlets are able to handle the additional electrical load without overloading the circuit. Additionally, outdoor outlets are often exposed to the elements, which can increase the risk of electrical shock and other hazards. If you must have an outdoor outlet on the same circuit as an indoor outlet, be sure that the circuit has the capacity to handle the additional load.

If your outlet needs to be reset multiple times, you likely have a problem with the outlet, the reset button, the wiring, or its connected circuit breaker. If the reset button doesn’t work and the circuit breaker isn’t the issue, it’s likely a problem with the outlet or the reset button it’s attached to.

To install an outlet from existing wiring, you’ll need to choose a location where you can already access existing wiring. The easiest way to do this is to install an outlet on the other side of the wall of an existing outlet. 

Since the wiring is already in place, all you have to do is connect a new cable to the existing wiring and then connect the correct wires through the wall—to the new electrical outlet. Place your new outlet into the opening in the wall and then connect the correct wires to the appropriate terminal screws.
