"Marcus did a great job, figured out my electrical problems, put up 2 ceiling fans, added an electrical outlet in my garage. Also cleaned up everything and moved back everything he touched. He was a very pleasant person and explained everything he was doing. Wouldn't hesitate to hire him and Photon electric again. Thank you Beverly"

"We got a list of electricians from Home Depot, and Singh was the first to call us. He came right away on Saturday, gave us a link to buy the fan, and came again next Saturday to install. He has done everything quickly and very professionally. It was a pleasure to communicate with him, as he replied very quickly. He will be our preferred electrician from now on."

"Despite a -12 windchill, Kevin and Jose sent a notice 30 minutes before their arrival and got to work immediately. They were both extremely courteous, professional, knowledgeable, and industrious. The project was extensive but they managed to keep power interruptions to an absolute minimum. Considering that the generator project required work involving gas, electric, and internet, their presence in our small house went almost unnoticed. I would absolutely recommend them. Great work!"

"Jim for Donhohues Lightning Rods installed the lightning rod system in my home. When the work was done I was very happy as their installer came as per promised time, and perform the work. Before giving them the work Jim completely sold me their work ethics, quality, and service. There was a minor issue and his team took complete ownership of this issue and talked to me in detail. They provide a very good explanation to satisfy me. I am a happy customer."

"William , the owner contacted me soon after I left a message on his phone. He was very prompt in getting me a quote for lightning rods that same day and happened to be in the area locally. We scheduled for him to install two days later. We were very happy with their work, meticulous and detailed. We canâ t notice any rods from the front of the house and they do their best to hide the cable so you canâ t see it. Our house got hit by lightning a year ago and it is not something I want to go thru again with the rebuilding of our house. We have a peace of mind that our house has protection now. William was very reasonable as far as cost compared to the other quotes that we got from other companies. We are so happy we found a great company that is honest and does good work. His company comes back every five years to check that the rods and cables are in good working order!"

Electrical FAQs, answered by experts

The cost of fixing faulty wiring depends on the type of repair required. Replacing an electrical service line, for example, can cost up to $500. Rewiring an entire house will cost at least several thousand dollars. Replacing old wiring like knob and tube wiring will be even more expensive, but fortunately that kind of outdated wiring is fairly rare. Always get an estimate from a reliable electrician to learn the cost details. 

Many wire nuts can accommodate three wires of various gauges; you should check the packaging of the nut to confirm you are buying the correct size. In addition, there are screw terminals that accommodate various numbers of wires; these might also be called “terminal blocks,” and exist to connect multiple wires. 

The safest option is to let a technician conduct the inspection. However, if you are certain that the capacitor failed and you take all precautions to avoid electric shock, you can take a look yourself. Usually, you can open the front panel of the unit and use a flashlight to find the small capacitor cylinder. It should have a sticker on it that provides its product number, capacity, and similar information that you can note when talking to a contractor.

You can twist the wires before using a wire nut, but it’s not necessary. Electricians often twist wires before using a wire nut, which can help secure the connection and enhance electrical contact between wires. You can decide whether or not to twist the wires beforehand, or consult a local electrician if you need  professional opinion.

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.
