"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

No. Do not use a 14-gauge wire on a 20-amp outlet. A certified licensed electrician would know that the National Electrical Code (as per Section 240.4(D) subsection 3) requires 14-gauge wires to be used with a maximum amplitude of 15. Therefore, you should only use 12-gauge wires on 20-amp outlets.

Different fences use different amounts of electricity, but their operating costs are very low overall. Electric fences pull between 4 and 25 watts from the system if you have an average-sized yard. Barring any complicated math, you can expect an average electric fence to cost less than $5 a month to run. Aboveground electric fences, which are not typical for residential use or small animals, can cost more, but you shouldn't notice a significant change in your electric bill. 

Light switches can last for decades when installed and maintained correctly. Improper wiring, heavy wear and tear, or too much wattage draw can cause light switch failure long before the expected end of a light switch’s life. Light switches that are hot to the touch, making a buzzing noise, or failing to work consistently should be inspected to find and repair the underlying cause.

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, the majority of appliances that run at 240v will work with a 220v outlet, but will often run slower and may have a slight delay in turning on. This could also cause long term damage to the appliance being used, so it’s recommended to always use the correct voltage for your appliance and upgrade to a 240v outlet if needed.
