"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!"

(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"

"Called and was scheduled for the appointment 2 days later. They called before coming over and actually arrived faster than expected. He was able to determine what was wrong with the door bells and fixed them quickly. He said he would have to trouble shoot the light fixture but suggested changing all 3 of the light bulbs. Well, that was all that was needed. Color me embarrassed. He asked if there was anything else he should look at, which was very nice. We will call them for any future electrical needs."

Electrical questions, answered by experts

Smart light switches are designed to be compatible with most lights and traditional home wiring, but there are several key factors to check. First, verify your home's wiring, as some smart switches require a neutral wire to operate, which may not be present in older houses (often built before 1985). Always check the wiring requirements for the specific model you choose. Second, consider your light bulbs; while smart switches work with almost any light, using a dimming feature requires dimmable bulbs, such as dimmable LEDs. Finally, ensure you have the necessary network connection. Most smart switches need a Wi-Fi connection for remote control, but some older models might use other standards like ZigBee, which would require a compatible hub.

If a 3-way switch is wired incorrectly, this can cause several issues. The most common problem is that the switches will not function properly: Either both switches won’t work, or only one will. Another issue is that one switch will trigger a short circuit, tripping the circuit breaker.

Single-pole switches are simple circuits designed for lower voltages. As such, they don’t require the complex wiring of switches that need to supply power to larger devices and appliances. This is why single-pole switches commonly go in bathrooms, closets, and other small rooms that power a low-watt light fixture. One wire creates the circuit from the power supply, the other goes to the fixture, and the final wire provides safety mechanisms through grounding.

Before hiring an electrician, check out the contractor’s official website, read reviews, and look them up on your local Department of Labor’s website. If you’re hiring for a complex job, pay special attention to their level of expertise. Also, call up pros directly to ask about their insurance status, specifically liability insurance, and request customer references.

A bigger breaker alone probably won’t fix your problem of frequent tripping. But if you upgrade an electrical circuit to a higher amp rating, or upgrade your breaker box to handle more amps, it could solve your tripping problems. Consult a qualified electrician about the best course of action.
