"I had a car charger installed and was really happy with the work. He was responsive, showed up when he said he would, and the install came out clean and professional. Everything was explained clearly, the work area was left neat, and the charger works exactly as it should. Definitely someone I?d recommend if you need electrical work done."

"The problem turned out to be a burned out small electric door switch. I believe the price was way too expensive for the service performed and the price of the door switch. What more can I say? It got done."

Electrical questions, answered by experts

Switching the hot and neutral wires in an outlet or receptacle, a condition known as reverse polarity, is dangerous. While the outlet will still function and provide power, it creates a significant electrical shock hazard because anything plugged into it will remain electrified even when switched off. If you touch a conductive part of the appliance, such as the metal components of a toaster, you could receive an electric shock.

While not always necessary, wiring your circuit breaker in a certain way can ease both the installation process and use afterward. For starters, you’ll need to install the electrical panel so that the main service knockout aligns with the cable conduit. If they aren’t aligned, you may not have sufficient working space to finish running the wires. Using cable trays, on the other hand, gives you a bit more freedom to and flexibility in where and which direction you install the wires. At the end of the day, the power flow will be the same whether the cords run up or down.

Wiring can last anywhere from 50 to 70 years, but all kinds of mishaps can occur that reduce the lifespan of your electrical wiring, including severe weather conditions, pests, and even faulty wiring. Keeping a preventative maintenance scheduling and hiring an electrician for an annual electrical inspection will keep your wiring system around for as long as possible.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

There are a few reasons your lights may be on, but the rest of your electrical outlets and appliances are not working. The first is that while one circuit blew out, the lights may be on another circuit than your other electrical fixtures. Alternatively, your powerless appliances may be plugged into a GFCI outlet that was tripped and needs to be reset. If these issues aren’t responsible for the problem, you may have dead outlets or a wiring issue. Either way, you should contact an electrician to identify and fix the issue.
