"I couldn't have asked for a better experience. They were hired to replace the main electrical panel/breakers at my elderly mother's home. Roni, the electrician, was a wonderful communicator, and was very knowledgeable and thorough in completing the job and in putting her at ease. The price was very reasonable. I will be using Nasr Electric in my own home, as well as recommending them to all my friends and family in the DMV area."

"not just professional efficient! Unbelievably fair priced literally less than half of what a major competitor on this site quoted using my own parts and my own wire! Just because there are any energy list doesn’t mean some people won’t try and rip you off and fools will pay it. Mr. NAGY is a professional and very ethical. I’d recommend hiring him again and again!"

"Very responsive, extremely knowledgeable, excellent problem solvers. They kind of really solved the mystery of why the generator didn't work that had to do with the electric."

"I have been hiring Cody Malone since we purchased our house in July 2012. They have switched out outlets, installed indoor ceiling fans, installed outdoor ceiling fans, ran electrical to my outdoor water feature and switched out my light fixtures. I plan to hire them again when I add electric to my detached garage. They always do a great job and arrive when they say they will. I have never had a single issue and they have been to my house for no less than six different projects!"

"Fox Trail Electric is a pleasure to work with. I’ve used this company for small jobs such as replacing outlets to bigger jobs of installing a new electrical box and running electric outlets outside. They consistently complete jobs in a timely manner and always clean the area when finished."

"They electricians were very professional. We communicated before the appointment so they would know exactly what make and models of fans and TV I wanted installed, and they came prepared. Everything worked exactly like they told me it should, and they ended up installing everything in less time than we planned. They did an outstanding job and I plan on calling them back to install another TV in the near future. I suspect I will use SciFiHomes for all my electrical needs in the future. I really was that impressed. The work was performed in Fredericksburg, VA - Not Woodbridge."

Electrical questions, answered by experts

Homeowners should avoid replacing a circuit breaker without turning it off. While you technically can replace a circuit breaker without turning off the main breaker—and professionals can and do—it’s only safe for electricians to use this process. Working with a live panel is extremely dangerous if you don’t have experience working with electricity. Always follow safety measures to avoid electrical shock.

If you’re wondering if you can use your electric vehicle as a backup battery, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.

They can vary—a lot. For example, while the EU continues to move toward broader standardization, many different types of outlets still exist from country to country. Some local standards cared about polarization, and some didn’t. It’s similar to other countries around the world.

Generally, you’re less likely to find polarized outlets outside North America. However, alternative plugs and outlets often incorporate precautions so that accidentally touching live prongs on a plug is hard or impossible. You may also find interesting regulations overseas that limit the use of outlets in bathrooms or near sinks to decrease the chance of shock.

Choosing a unit with higher BTUs can use more electricity if the BTUs are more than what’s necessary for your room size. However, choosing an AC with BTUs that match the size of your room or house, your unit will cool your space efficiently. On the flip side, choosing a system with not enough BTUs can cause the system to work harder to try to cool the space, leading to more electricity consumption and higher energy bills.
