My name is Scott Nelson. My company is called "SCOTT NELSON ELECTRIC" because I want my own name to be on every job we do. I have been in the electrical trade for over 35 years. I went to trade school school through "Associated Builders and Contractors Electrical Apprenticeship Training Program"(A.B.C.)shortly after completing high school. I am noticed by the "National Bureau of Apprenticeship Training"(N.B.A.T.)as a Journeyman Electrician. I worked for 14yrs. with contractors from the north shore, NW suburbs, and northern Illinois. "QUALITY ELECTRICAL REPAIRS & INSTALLATIONS" is the best way to explain our service. We believe that being "neat & tidy" is one of the best ways of showing how much we respect our customers and their homes. Our goal is 100% customer satisfaction.

"Nelson Electric is the best electrical contractor I’ve used in my thirty-eight years of owning and updating my homes. It is difficult to find an excellent contractor who is willing to take on a major remodeling project in old construction, and who handles it efficiently, cost-effectively, and with perfection. This time we were remodeling a 110 year-old bathroom. When we got down to the studs, joists, and rafters, the plans were worthless because of all the surprises. Unphased, the crew was able to trace every hidden wire to destination and source, re-route them as needed, install a new, larger, circuit breaker box, pull wire through neatly, clearly identify and label everything, and finish beautifully the lighting, overhead heating, floor heating, and exhaust fixtures, making for a beautiful bath. Thank you, Scott!"

Electrical questions, answered by experts

Incandescent lights are glass bulbs with metallic filaments inside, while LEDs feature “light emitting diodes” that illuminate when they come in contact with an electrical current. You can buy either for your Christmas lights, but note that LED lights are more energy-efficient and have a longer lifespan.

A light switch can stop working for several reasons. Typical causes include a blown fuse or tripped circuit breaker, both of which shut off power to the switch. Worn-out or faulty internal switch components can also prevent it from functioning properly. Loose or disconnected wiring within the switch or electrical box is another frequent issue. Additionally, switches may fail due to age, excessive use, or physical damage. In some cases, problems with the light fixture or bulb itself might be mistakenly attributed to the switch.

The standard voltage for United States power outlets isn’t shared around the world, and neither is the shape of the power connector. This is why you need travel adapters when spending time abroad. Where the United States typically uses 110/120V outlets, outlets in Europe typically use 220/240V. Power outlets can vary in other ways around the world, too. Not everyone uses the 60Hz frequency, for example, and not everyone even uses AC power in outlets. Always do your research when traveling to see what you need.

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.

On average, it takes from four to eight hours to replace an outside electrical meter box, not including rewiring. It will take a few more hours if the project requires pros to do any rewiring work. Consult your local electrician about a time estimate for your specific project.
