"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!!!"

"Second time using B-Tec electric and I think now they are my go to electrician. I used them previously to upgrade my panel to 200 Amp and this time to hook up my new electric water heater. Both tasks were completed perfectly and fairly priced. I highly recommend B-Tec electric!"

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."

"Bill and his team were outstanding. They accomplished a large electrical task in short time and even reorganized the circuit breaker and rewired some old 220s and converted to 110s. Highly recommend and would use them again on future projects."

"Chris at ARS Electric was both knowledgeable and friendly. He and his coworker were able to come for my small bathroom exhaust fan installation job the day after I inquired on Home Advisor. Accessibility to contractors these days is never that fast. I highly recommend the services if ARS Electric."

Electrical questions, answered by experts

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

Yes, you can put a GFCI outlet in almost any electrical outlet location. As long as the outlet is wired correctly back to a circuit breaker, you can likely replace the existing outlet with a GFCI outlet.

Yes, tamper-resistant outlets are designed to be safe for use in homes with children. They feature a spring-loaded shutter that blocks the electrical slots when not in use, which helps protect children from electric shock if they try to insert an object. While they are the safest option available and highly effective, it's important to note that few things are truly 'childproof.' Children may still try to imitate adults by inserting a plug. For this reason, it's best to use tamper-resistant outlets over less effective solutions like plastic covers, which can be removed or pose a choking hazard. Always supervise young children around any electrical outlets or devices.

How far you can run underground electric depends on the wire gauge (generally AWG) and the circuit voltage. Too much voltage drop in an electrical circuit can negatively affect performance, so the smaller the voltage drop, the better. Ideally, it shouldn't exceed 3%. The smaller the wire and the longer the run, the more significant the voltage drop. 

For example, with a 120-volt circuit, you can run 60 feet of 12 AWG cable without losing more than 3% voltage. With a 240-volt circuit, you can run 120 feet of 12 AWG wire while maintaining a voltage drop of 3% or less.

Yes, you must use an extension cord specifically rated for outdoor use to power outdoor lights, such as Christmas lights. Extension cords intended for indoor use lack the protective properties to withstand exposure to outdoor elements. To safely hang and power lights outside your house or in your yard, always connect them to an outdoor power source using an outdoor-rated extension cord.
