"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."

"There was a buzzing sound coming from an electrical wall panel in my house. I was extremely nervous about the unknown problem and appreciate Hamilton’s electrical prompt response. The issue was resolved. I appreciated their willingness to come out as the office was closing at the end of the day. Kudos to them for the professionalism and concern that they had for the customer. I highly recommend them and will contact them for my upcoming electrical projects!"

"I am an Electrical Engineer by education and trade, working for several high-tech firms in Silicon Valley over a 45-year career, so I've never felt the need to call an electrician. But I know my limits and repairing an electrical open circuit routed in underground conduit is one of them. After trouble shooting the issue, I knew there was a break in the line so I called Mike at M3 electrical. He put me on his schedule, showed up on that date (even a little early) and in less than two hours had the issue fixed. Not only that, but he advised the type of 2-wire Romex that had failed was not the proper wire for an underground application. He pulled about 75 feet of the proper wire through the conduit and even installed a junction box at my street light for a clean installation. Costly you think? Not in my opinion! If I ever need electrical work done in the future, Mike is the guy I will call. I suggest you do as well. Mark S. A very happy customer"

Electrical questions, answered by experts

If the electrical wires you’re working with are too short, one of the easiest ways to elongate it is to extend them with a push-in connector. These user-friendly tools help you splice two wires together with little fuss or the need for extra tools, like a crimping tool, which is an older way of extending wires. As long as you can stripe the ends of a wire, using a push-in connector shouldn’t be an issue.

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.

Choosing between 12- or 14-gauge wire for your house depends on the electrical requirements of the circuit. A 12-gauge wire is thicker and can handle more power, making it better suited for devices such as kitchen appliances, air conditioning units, or electric heaters.

A 14-gauge wire is thinner and can handle less electrical current than a 12-gauge wire. It's ideal for circuits with lower power requirements, such as lighting or general-purpose outlets in bedrooms or living rooms.

In many cases, yes, upgrading your electrical panel can lower your electric bill. Upgrading an outdated electrical panel can make your home more energy-efficient, so you consume less electricity and spend less on utility bills. However, to see these savings, you’ll need to invest quite a bit. On average, installing a new electrical panel costs $1,200 to $2,000, with most people paying around $1,600.

Upgrading a two-prong outlet to a three-prong outlet typically costs between $20 and $50 per outlet if the electrical box is already grounded. However, the cost can increase significantly if the system is not grounded, as this may require grounding the box or upgrading your electrical panel. Electricians generally charge between $50 and $100 per hour for labor, and the total cost for a more complex installation could range from $130 to $300.
