"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."

"We had an excellent experience with this electrician at our 120,000 sq ft office building. He came out to perform repairs and upgrades on our electrical systems and delivered truly professional, high‑quality workmanship from start to finish. His knowledge, attention to detail, and clear communication made the entire process smooth and efficient. It’s not easy finding someone who can handle large‑scale commercial electrical work with this level of skill and reliability. He showed up on time, worked safely, and made sure everything was done correctly the first time. I highly recommend him for any commercial or residential electrical needs. Outstanding service and professionalism"

Electrical questions, answered by experts

If all of the outlets in one room suddenly stop working, it’s likely the result of a tripped circuit breaker. This easy-to-resolve malfunction is caused by overloading the circuit with too many working appliances at the same time. Locate the tripped breaker in your electrical panel and reset it to restore power.

You can check if an electrician is licensed in California by using the online check a license tool offered by the Department of Consumer Affairs Contractors State License Board. You have the option of searching by the license number, the electrical contractor’s name, or the name of the business to determine the electrician’s status.

GFCI stands for ground fault circuit interrupter, which means it has the ability to detect a ground fault and shut the circuit down before it creates hazards. General breakers may also do that because ground faults can cause overloads, but they’re more focused on amp overloads from any cause. GFCIs are often installed in specific outlets, but breakers can come with GFCI capabilities built in for broader ground fault protection.

If there isn’t a C-wire on your thermostat, you can repurpose the G-wire. The G-wire controls the fan independently of the other controls on your thermostat, so the fan-only function won’t work if you decide to go this route.

While most electrical items can be plugged into a GFCI outlet, some appliances with internal or stationary motors, such as refrigerators, vent fans, and fluorescent lighting, can cause nuisance tripping. This happens because they experience a small, normal amount of current leakage, which can cause the GFCI to trip even when the appliance is working correctly. Although this is not a safety hazard, it can be inconvenient and may cause the GFCI outlet to wear out faster. For this reason, it is often better to plug these types of appliances into a standard outlet. Additionally, electrical circuits over 100 feet long can sometimes cause tripping. Some appliances, like hair dryers, have their own built-in GFCI protection, so connecting them to a standard outlet is fine.
