"I highly recommend First Class Electric. I called this morning and by 10 am Joey the technician was calling me confirming he was on his way. The operator who made the appointment was very friendly and helpful. The technician Joey was very knowledgeable and friendly. He is an asset to your company! He understood what needed to be done and explained his plan. He made sure I was satisfied and answered every question. I will definitely use this company again but I want Joey to be the technician. Thank You!!!"

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

If you have a lamp that flickers or doesn’t stay on, it’s a sign that it’s time to rewire it. Additionally, it’s important to rewire antique lamps so they’re safe to continue using without the risk of an electrical fire. If the plug on your lamp is more than 15 years old or you notice poor performance like flickering, you should hire a lamp repair service to rewire it. If you’re upgrading the bulbs in an antique lamp from incandescent to LED or CFL bulbs, rewire it so it’s compatible with the modern bulbs.

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.

In most cases, line wires are located at the bottom of a panel or device, while load wires are located at the top. Line wires are generally black, while load wires are typically red or black. To tell for sure, you can use a multimeter or volt pen to test the wire. A live or line wire will always carry a charge, while a load wire will only carry a charge when it’s in use.

Ultimately, the best device depends on what you’re measuring. A voltmeter only measures volts, while a multimeter measures volts, current, resistance, humidity, and possibly much more, depending on the model. If you think you’ll need to measure more than volts, consider investing in a multimeter so you have a tool that can help you with various household projects.

If you’re interested in exploring other avenues to completely upgrade your electrical panel, it’s also possible to add a sub-panel, which is a smaller panel that connects to what you currently have in place. This way, you can add additional circuits without having to swap out your main panel.
