"ELI was wonderful! He arrived on time, was friendly, thorough and quick. What really impressed me was ELI'S attention to the little details--he made sure no water, garbage got loose under the counter, used a mat to protect my floor/inside counter, cleaned up everything--even my sink--when he was done and, finally, put everything back under the counter where it was before he came! Above and beyond customer service! I will recommend AAA who anyone who needs drains unplugged! Also I like the company and especially the SERVICE so much, I'm meeting with a tech for another job--electrical this time. THANK YOU, ELI for your time, service and patience with my speech! much appreciated!"

"My husband with Alzheimer’s can usually change a light switch but while doing the one in the bathroom couldn’t get it. I put an urgent message on Angie’s list and Terry from Zap electric gave me a call in a few minutes. He came and fixed the switch in 20 minutes. He was knowledgeable and so nice. He gave us a senior discount. A bathroom light is a must and he saved me that day. Please call him of you need any electrical!"

"I had an excellent experience with Austin — he called me within 10 minutes of submitting my request on Angi’s List. He arrived at my home within half an hour and got straight to work converting an old cable outlet into a new electrical outlet in my living room. The job was done quickly, cleanly, and exactly as requested. I also asked him to rewire my current outlet so it wouldn’t be controlled by a wall switch, and he handled that with no problem. He was prompt, professional, friendly, and genuinely happy to help — highly recommend!"

Electrical questions, answered by experts

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.

No, you don’t need to hire an electrician to install your garage door opener. Garage door professionals have the skills and expertise to install the wiring necessary to connect the opener to your home’s wiring system. When hiring a local garage door professional to install your system, make sure the opener task is included in the list of provided services.

Yes, you can plug an extension cord or an outlet extender into a GFCI outlet. The GFCI outlet will still be able to protect your system in the same way.

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.

Yes, the National Electric Code (NEC) requires at least one GFCI outlet in each sectioned-off portion of an unfinished basement, partly to ensure a power source is available for a sump pump in case of flooding. If you install multiple outlets in your unfinished basement, all of them must be GFCI-protected. For finished basements, standard outlets are generally permitted, but at least one GFCI outlet is still required per circuit. Keep in mind that local municipalities may have additional codes, so it's best to consult a licensed electrician to ensure your home is fully compliant.
