"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."

"Single Line Electric came to my house to view my need. 2 other companies I called wanted me to send a video of my home showing them my yard from the electrical box to my pool. They obviously didn't want the job. Nery came out and did a thorough assessment of my needs. His quote was reasonable and the project began soon after. I am very pleased with with Single Line Electric"

Customers say: Quality work

"Stephen was knowledgeable about the Code requirements for Oakland (not all of the electricians who quoted on the job were) and flexible in working through the equipment needs (a panel and a subpanel). He and his crew (Jeff and Tom) were quick, clean and efficient in the installation and the price for the work was fair. I definitely would hire them again if I need more electrical work."

Electrical questions, answered by experts

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.

An outlet can start a fire if it has blown a fuse, or is sparking, overheating, or smells burnt. Prevent electrical fires by unplugging the device connected to the outlet and hiring an electrician to determine and fix the outlet’s issue. If the outlet stays hot or isn't working, you should fix it.

A home electrical inspection usually takes one to two hours. Full home inspections fall on the longer side, while code compliance inspections that focus on a single repair or installation may only take a few minutes. Optional add-ons like infrared inspections can add time, but these aren’t usually included in your standard inspection.

If only half of your outlet works, there are usually two possible causes: faulty wiring or a half-hot outlet. The first thing you'll want to do is check the circuit breaker panel to ensure that it's not tripped. If your circuit breaker isn't tripped, turn off the electricity and inspect the wiring to see if anything has come loose or corroded. 

If you have a half-hot outlet, it means half of the outlet is controlled by a switch somewhere on the same circuit, which should be nearby. This is an intentional electrical design commonly found in rooms without overhead lights.

The number of outlets and lights you can safely run on a single circuit depends on the circuit's amperage and local electrical codes. A general rule is to allow one outlet or light fixture per 1.5 amps, keeping the total load under 80% of the circuit breaker's capacity. For example, a 15-amp circuit can typically support up to eight outlets or lights, while a 20-amp circuit can accommodate up to ten. Always consider the combined power usage of all connected devices and fixtures to prevent overloading. For specific guidelines and to ensure safety, it is best to consult local electrical codes or a licensed electrician.
