"I had a great experience with All Phase Electric on the work done for an electrical panel and plug upgrade. The team was professional, punctual, and clearly skilled at what they do. They explained everything thoroughly, and completed the work efficiently, and left the area clean. I’m very satisfied with the quality of the work and would definitely recommend them for any electrical needs!"

"We had Peyton change out some fixtures, add new can lights in the bedrooms and run electricity to our chicken coop. He did a great job, very little clean up and most of all, he was professional and very affordable! We highly recommend him for anything electrical!"

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.

You should never unplug or touch a buzzing outlet. If there are appliances plugged in that are causing the buzzing, wait until the appliance is turned off (or turn it off yourself) and then unplug it from the outlet. Test the outlet by plugging in something that won’t use much power—a small lamp works well. If the outlet still buzzes, have a pro investigate why.

Yes, you must use an extension cord specifically rated for outdoor use to power outdoor lights, such as Christmas lights. Extension cords intended for indoor use lack the protective properties to withstand exposure to outdoor elements. To safely hang and power lights outside your house or in your yard, always connect them to an outdoor power source using an outdoor-rated extension cord.

Yes, in a new home, ground wires are mandatory. Some older homes may not be grounded, but if you decide to renovate, you will need to have your electricity grounded at that time. Remember, grounding helps keep everyone in your home safe from sudden electrical surges. It’s best to hire an electrician to inspect and work with your home’s wiring.

Wire color codes vary depending on the region. For instance, the United Kingdom has updated its wiring codes to match Europe's color system. The United States wiring color code is different, as is Australia's. Because the color code system isn’t universal, it’s essential to hire an experienced electrician to perform any electrical work to ensure it is done correctly.
