They were prompt, courteous, and efficiently resolved both issues. The doorbell chime works perfectly now, and the lighting is brighter than ever. I highly recommend them for their excellent workmanship and professionalism. Thank you for your excellent work!"

Customers say: True professional

"If you're looking for an honest and knowledgeable electrician, R.A.P. Electric Company is the real deal. When my master bathroom outlets suddenly lost power, I spent hours checking breakers, outlets, and GFCIs without finding the problem. After contacting R.A.P. through Angi, I expected a service call and a bill. Instead, the electrician took the time to ask a few questions and patiently guided me through troubleshooting over the phone. He helped me locate a forgotten GFCI outlet in my basement that had tripped and was causing the problem. Once I reset it, everything worked perfectly. Many electricians could have charged me for a house call to perform a 30-second fix. Instead, R.A.P. chose honesty and customer service over making a quick dollar. That level of integrity is rare these days. I will definitely use R.A.P. Electric Company for any future electrical work and highly recommend them."

Electrical questions, answered by experts

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

The process of hiring a reliable electrician begins by searching for local professionals and verifying that they hold a master electrician certification and the proper licensing for your area. After that, you should read through reviews from past customers to see the kind of service you can expect from the contractor, as well as look at the Better Business Bureau’s (BBB) website to check for a history of company complaints. You can also ask for customer references to make sure you’re choosing a reputable professional.

The life expectancy of a circuit breaker is 30 to 40 years. However, how long your circuit breaker lasts depends on the condition of your electrical equipment, the amperage, your electrical consumption, and more. A breaker box that frequently trips from overload will last much shorter than a breaker box with the proper amperage for the number of devices and appliances in use. If your circuit breaker trips frequently, and you have also increased your electrical consumption, it may be worth upgrading your electrical panel to extend your electrical system’s lifespan—and save you the hassle of frequent power trips.

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.

Well pumps need power to run, so they can’t function without electricity. If your power shuts off, there can sometimes be enough pressure in the water tank to allow for a lucky flush or a bit of tap water—but this won’t last long. It’s a good idea to have a backup generator or an alternative power source like solar if you’re worried about losing power.
