"Neil showed up on time. Give me an estimate. Performance to work flawlessly. I was very happy with his professionalism. He took the time to instruct me on how to work my generator with the new transfer switch. Very highly recommended. He also installed an outlet on the outside of our house."

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

Yes, it is possible to hang a chandelier without wiring, but it depends on the design of both the chandelier and your ceiling. Many homeowners use plug-in pendant lights, adhesive hook and cord pendants, or nonelectrical light sources to hang a chandelier without wiring.

With AC wiring, which is the kind most likely you’ll find at home, the black wire is “hot,” and the white is “neutral.” The bare or green wire is considered the safety ground wire. If you encounter DC wiring, it’s relatively easy to tell positive or negative wires apart. red wires are used to indicate positive voltage and black wires indicate negative voltage.

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

Just like apples in a bunch, one bad outlet can cause other outlets to stop working. This is especially true if the outlets are connected in a series on the same circuit. When one outlet develops a fault, it can spread to every outlet downstream of the original.

To check if doorbell wires are live, use a non-contact voltage tester. Hold the tester near the wires; if it lights up or beeps, the wires are live. Always ensure the power is off at the breaker box before handling any wiring. If you don't have a voltage tester, consider getting one or consulting a professional to ensure safety.
