"I hired Ken Johnson (Johnson Electric) to correct a number of electrical problems which were identified in a pre-sale home inspection. Among these was a replacement of an unsafe old circuit panel, all new power outlets, conduits and receptacles. Ken provided a quote which was very reasonable. Actual work was performed by two technicians. They arrived on time, completed the job the same day, and left the site in pristine conditioner. We were very satisfied with their work and based on my experience I am happy to recommend Johnson Electric for quality electrical projects in your residence."

"Electric Zone is a company that I would highly recommend. Haik is a consummate professional. He and his team are punctual, efficient, polite and very patient when answering questions. Previously, I had work done on my house and the contractor just left the project without completing it. The part that was not completed was causing a lot of problems and stress for my family. The circuit breaker kept tripping and one of the junction boxes melted an electric oven that we used to use. Electric Zone took care of the entire problem and left their entire working area perfectly clean. They left no debris anywhere. My family and I are extremely happy with Haik and the entire team from Electric Zone."

I am grateful that he knew exactly what to do as well as explained the process so I could understand. He worked quickly & efficiently. If I have any type of electrical issues in the future I will definitely ask for Tony. I've already recommended him to 2 of my friends."

Electrical questions, answered by experts

It might seem tempting to use 14-gauge wires for your outlets, as they can run a little cheaper. But, when it comes to electrical work, it’s best not to cut costs less you overload your circuit. A 12-gauge wire will ensure that you’re protecting the outlet (and your circuit breaker) from any potential overloads that might incur, as it can handle a little more amplitude than a 14-gauge wire.

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.

Wiring a light switch wrong can cause a fire if the incorrect wiring causes arcing, meaning the current jumps uncontrolled from one conductor to another. Loose wires or worn wires that are not repaired or replaced can cause arcing. If you’re not 100% sure you can do the job safely, don’t attempt to wire a light switch on your own.

Compared to amps, volts, and watts, ohms are a different kind of measurement, though also very common. Ohms show the resistance of materials like wiring: How much they impede the flow of electrons. The reason household wiring is usually copper or aluminum is that these materials are affordable and also have lower ohms, which means low resistance/high conductivity.

There are several indicators that a single-pole switch is bad: the switch is warm or hot to the touch, sparks are sometimes present when turning the switch on or off, you hear a buzzing sound or other weird noise coming from the switch, the connected light flickers when you turn on the switch, and the light doesn't turn on at all with the switch. If you notice any of these, replace the switch or call a pro straight away.
