"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!"

"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"

"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

A multimeter does not measure frequency, charge, inductance, and other electrical quantities. Instead, it measures voltage (AC and DC), current, and resistance.

Most ceiling light fixtures only have a black, white, and green wire, but in some cases, you’ll also find a red wire in the box. This is a second hot wire, like the black wire, and is included for ceiling light kits that have a fan.

The color of your cable will help you to identify its function. In the U.S., the National Electrical Code (NEC) designates the color code for electrical cables. “Hot” cables are black, red, and blue. In cases of higher voltage lines, orange might also be used to indicate a hot cable. White or gray indicates a neutral, and green or green with a yellow stripe indicates a ground.

Replacing the panel itself takes four to eight hours of work by a professional. However, if associated wiring and related components also require replacement, the labor time increases to 20 to 30 hours. Your electrician can speed up the process by bringing in a team of pros to handle ancillary tasks.

If your home already has wires for a ceiling fan (and optional light kit), then it’s quite safe to wire and install it yourself. Always be very careful to shut off the power before you begin, and confirm that the power is safely off with a non-contact voltage tester before touching anything. It’s also highly recommended to use eye protection, rubberized gloves, and tools with rubber handles to keep yourself safe from electric shock.
