"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."

"I highly recommend Sparks Electric. They recently completed an electrical box expansion, installed two ceiling fans, and replaced two bathroom fans in my home. Blake provided an itemized quote for a fair price before starting the job. His team arrived on time, were polite, and cleaned up after themselves. They also had excellent communication throughout the project. Iâ m very pleased with their work and recommend them to anyone looking for electrical work."

Electrical questions, answered by experts

While you can technically live in a home while it's being rewired, prepare for some debris and dust if your electrical contractor needs to remove parts of walls, floors, and ceilings to access wires. If you stay home during the project, ask your electrician to cut the power supply to all exposed electrical wires to keep your family safe.

To install an outlet from existing wiring, you’ll need to choose a location where you can already access existing wiring. The easiest way to do this is to install an outlet on the other side of the wall of an existing outlet. 

Since the wiring is already in place, all you have to do is connect a new cable to the existing wiring and then connect the correct wires through the wall—to the new electrical outlet. Place your new outlet into the opening in the wall and then connect the correct wires to the appropriate terminal screws.

Yes, a dead outlet can be dangerous and may cause a fire. The lack of power can be due to a hazardous electrical issue that poses a fire risk. If you notice a burning smell, discoloration, or sparks from a non-working outlet, it is a serious issue. It is vital to have a professional electrician investigate and fix the problem as soon as possible.

Most standard residential water heaters, which are typically around 40 gallons and use 240 volts and between 3,500 and 5,500 watts, require a 30-amp, two-pole circuit breaker. For smaller, point-of-use water heaters using 120 volts and between 1,500 and 3,000 watts, a 30-amp breaker is also often adequate. However, some models may have different needs; units that use more watts than average may require a 40-amp breaker, while smaller units might only need a 20-amp breaker. Newer, tankless, or more energy-efficient models can also require a higher amperage. Having the correct breaker size is crucial for safe and efficient operation, so it's best to consult a licensed electrician to determine the specific needs of your water heater.

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.
