"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."

"Just got a hot tub delivered and needed the electrical run to it. Mark and crew came out and installed a 50-amp GFCI breaker and ran conduit along the side of the house to a disconnect near the tub. Looked way cleaner than I expected. Passed inspection and we were soaking that weekend."

"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"

Electrical questions, answered by experts

Yes, but our analogy with the water hose doesn’t really work here. You see, electrical flow isn’t constant: It ebbs and flows like waves, coming in pulses of power. Hertz measures the rate of change in the flow of electricity, or how often it ebbs and flows. For example, 60Hz means that the electrons pulse through wiring 60 times per second. When they are pulsing, they’re in a brief retreat. Almost all United States equipment is rated for 60Hz.

Most electric water heaters have a built-in shut-off switch, so you can simply turn that to the OFF position. Some water heaters have the switch inside a panel, so you might need to unscrew the panel, remove it, move aside the insulation, and then shut the water heater off. To make sure it’s off, you can also locate the switch for your water heater in your electrical panel and shut the power off there. Most electrical panels have dedicated switches for the water heater, so you can shut off the power without affecting the rest of your home.

Yes, the National Electrical Code (NEC) requires that outdoor Christmas lights be plugged into a ground-fault circuit interrupter (GFCI) outlet to prevent hazardous electrical shocks or an electrical fire. It’s a code violation to plug outdoor Christmas lights into a non-GFCI outlet, so be sure to follow these guidelines for a safe and successful installation.

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.

Rewiring projects cost anywhere between $1,500 and $10,000 on average, depending on the complexity and the size of the rewiring. You can anticipate spending between $2 and $4 per square foot of wire, including labor and materials. Wire material ranges from $0.25 to $1.60 per linear foot.
