"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."

Customers say: True professional

"Ivan and Edgar were amazing! I originally brought them on board for an EV charging outlet to be installed in my detached garage. After a quick assessment, we learned I would need to have a new electrical panel installed and a new line run under the home to the garage. The work was done quickly and flawlessly. Their price was also very competitive to many of the quotes I was provided from other teams. On top of that, Ivan and Edgar were extremely professional and friendly. I plan to also hire them for a recessed lighting project in my living room, which I learned is their specialty. Thank you IC Electric for an amazing instal!"

Electrical questions, answered by experts

Yes, placing an electrical panel in a bedroom is perfectly acceptable, so long as it meets other space requirements as indicated by OSHA and related agencies. When installed in a bedroom, electricians typically place it in the area directly behind the door swing. This method allows for easy access when conducting electrical panel repairs.

A piggyback circuit breaker, also known as a tandem or double-stuff breaker, combines two separate circuits into a single slot in a breaker panel. This design allows adding more circuits without a larger panel, making it a space-saving solution. Each breaker in the piggyback unit operates independently, protecting two circuits in one standard breaker slot. This is especially useful in older panels with limited space for additional breakers.

If you’re outlet isn’t working but the breaker isn’t tripped , that could mean a number of things. First, check if it’s a GFCI outlet, which has added protection so your breakers don’t malfunction. If that’s the case, simply hit the outlet's reset button and see if it works. If it doesn’t, or you don’t have a GFCI outlet, you might have a loose outlet or loose wiring, a damaged breaker, or an overloaded circuit, which would require a dedicated breaker. It’s best to consult with an electrician to diagnose the problem accurately.

When converting a standard 120-volt outlet to a 240-volt outlet, the only components you can typically reuse are the existing electrical box and the hole in the wall. Everything else—including the wiring, breaker, and receptacle—should be replaced to ensure both safety and efficiency. Appliances designed for 240 volts have different plug configurations that won’t fit into a standard 120-volt outlet, making it necessary to install a compatible 240-volt receptacle. This design helps prevent overloading or underloading the power available to any one outlet or circuit.

If your home already has wires for a ceiling fan (and optional light kit), then it’s quite safe to wire and install it yourself. Always be very careful to shut off the power before you begin, and confirm that the power is safely off with a non-contact voltage tester before touching anything. It’s also highly recommended to use eye protection, rubberized gloves, and tools with rubber handles to keep yourself safe from electric shock.
