"As a Building & General Contractor myself Newgrange electric is one of my best electrical sub contractors. Eddie the owner is very hard working. Always reliable, extremely professional and maintains an office manager Nicole who knows what's going on, on all their projects so you always have someone to contact during business hours. Eddies crew is based of long time employees that are very knowledgeable in there work. Eddie will always get back to you even after business hours, which is not the norm for many vendors. We need more contractors like this. Joe Algeri, Orchard Builders & Construction & Skyline Plumbing & Heating."

"No Shorts Electric helped me bring my 1950's era family home into the 21st century by updating the electrical panel. They are professional & easy to communicate with, plus they did a great job. Finally, I can have all the outlets I need. I am already working with them on a second project!"

Electrical questions, answered by experts

It’s possible to distinguish a positive black wire from a negative black wire if you know what type of circuit the wires are in. If it’s an alternating current (AC), then black wires are positive. If it’s a direct current (DC), then black wires are negative. 

Sometimes, a circuit has two black wires. In that case, the positive black wire will be solid black while the negative black wire will have a white stripe on it. If you’re still unsure, you can use a multimeter to check.

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.

Your outlet should be a ground-fault circuit interrupter (GFCI). These outlets will cut power off in the case of an electrical fire, keeping your home and family safe. Extension cords can also be GFCIs. A local electrician can replace older outlets with GFCIs, if necessary.

Electric bills tend to be lower in spring and fall because people use less electricity during these seasons. Milder temperatures allow for less use of heating and cooling, unlike during winter and summer, which usually bring more extreme temperatures.

Yes, splicing wires can cause a fire if the splicing is done incorrectly. This is why splicing wires is a task best handled by electricians. One of the most common mistakes made when splicing wires is not using a wire connector. Without a wire connector, electricity flows unsheathed and can result in a home electrical fire.
