"Excellent service. I needed to upgrade my electric panel, Ben did an excellent job very professional. Installing switches, circuit breaker panels, relays, and other electrical control and distribution equipment was the right call. I look at several electricians with reasonable prices and CA Electrical Group was definitely the right call. I will highly recommend CA Electrical Group to all my friends. What was important to me was his daily commitment to start and finish the job the dates we agreed on."

"Michael and his technician were very prompt, very helpful, and very accommodating. It was late in the day, and I made an attempt to get my electrical issues resolved the same day (because problems could potentially worsen) - Michael, without hesitation, coordinated to have his technician meet with me asap! Technician did a great job analyzing and fixing the problem. Excellent customer service! Will definitely hire for future needs."

"I needed to have a charging station installed in my garage after purchasing an EV Bolt. I didn't know of any electricians and so I tired Home Advisor. I filled out a request on Sunday and Monday morning Tony Munguia called to say he could come at 1 PM to give me an estimate. He was promptly at my front door at 1 PM and he was very thorough in his estimate. He used a calculator on his phone to see if the correct wire size would fit in my existing conduit that went from our house to the detached garage. He was very personable and I connected with him while he explained his estimate. I accepted it and he and crew came promptly at 8 AM and excellently install the craving station in my garage. They cleaned up after themselves and completed the jon by 4:30 PM. I now k now of an excellent electrical contractor in Marin should I need one in the future. I would highly recommend their services."

Electrical questions, answered by experts

It’s possible to distinguish a positive black wire from a negative black wire if you know what type of circuit the wires are in. If it’s an alternating current (AC), then black wires are positive. If it’s a direct current (DC), then black wires are negative. 

Sometimes, a circuit has two black wires. In that case, the positive black wire will be solid black while the negative black wire will have a white stripe on it. If you’re still unsure, you can use a multimeter to check.

No, outdoor outlets are not required to be on a separate circuit. However, you should always defer to local electrical codes when making decisions about how to install your new outlet. An experienced local electrician will be able to inform you of all codes and requirements in place at your home.

Wiring or installing a light the wrong way can lead to potentially dangerous scenarios, including shock and even electrical fires. If you’re the least bit uncertain whether you’ve wired something correctly, the best and safest approach is to call in a professional electrician to handle the installation for you.

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.

A C-wire connects your thermostat to your household heating and cooling system to provide continuous 24V power. The furnace's transformer converts household electrical current into this low-voltage power to operate the HVAC system's circuitry. In most configurations, the C-wire connects to the terminals labeled "C" on both the furnace's low-voltage terminal block and the thermostat. In some cases, if a dedicated C terminal is unavailable, the C-wire can be connected to the "G" (fan) terminal at the furnace.
