"I am updating my rating for CA Electrical (Unfortunately Angi will not allow me to edit, so I am posting this as a new review). After posting my original review I was contacted by CA Electrical. The supervisor assured me that my experience was not their normal practice and that they normally made sure to call if there was a change of plans. I felt that they were earnest in trying to make things right, so I agreed to give them another chance. I ultimately decided to select them for my project to replace sub panel and install outlets. The crew was excellent and professional. They showed up on time, were professional and friendly, took extra care to ensure work spaces were left clean. Their workmanship was excellent and they did a great job of cleaning up some messy electrical wiring that had been there before. As an electrical engineer, I also appreciated the crews knowledge of code and ability to explain the technical side of the installation. I would use them again."

"I honestly wish that all service providers were like Raja from R&C electric, he was very respectful of my time as a customer as he came right on time, he was very professional and skilled as he gave me a very reasonable quote and in simple words explained what exactly is he going to do which made me feel comfortable with the work since electrical is not my expertise, then he finished the job in 2 hour which was honestly impressive given that all of the work was neat and high quality, then he cleaned up everything behind him and I was able to use my charger in no time. Perfect service and I was absolutely delighted with my experience with Raja, and Iâ m for sure calling him back for future projects. Thank you again Raja."

Electrical questions, answered by experts

The hot wire is typically black, but it's essential to use a non-contact voltage tester to confirm the electrical wire color code before working on it. Neutral wires are typically white. It’s vital to determine which wire is carrying electrical current before proceeding with any electrical work.

Yes, splicing wires can cause a fire if the splicing is done incorrectly. This is why splicing wires is a task best handled by electricians. One of the most common mistakes made when splicing wires is not using a wire connector. Without a wire connector, electricity flows unsheathed and can result in a home electrical fire.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

Modern homes have a lot of devices and appliances running at once. That means there are many different wires and cables throughout the house. Service entrance conductors (also known as service entrance cables or service feed wires) connect the external weatherhead for the utility pole to the circuit breaker box. This is your home’s connection to your local power grid.

The American Wire Gauge system calculates wire size diameters using the complicated formula D(AWG)=.005·92((36-AWG)/39) inch. A simpler rule of thumb is that every six-gauge decrease doubles the wire diameter, and every three-gauge decrease doubles the wire’s cross-sectional area. On the other hand, wavenumbers are typically measured in reciprocal meters (1/m or m−1) or reciprocal centimeters (1/cm or cm−1).
