"Apollo responded quickly to a quote request. I described the job, provided some photos, and they were able to quote without a visit to the house, which was much appreciated. We scheduled the work for the next week. The communication during this period was very fast and smooth. The electricians arrived on time, we're very polite and professional, we reviewed the job once more, they completed the work, confirming with me the final location of new receptical before cutting started, and before I knew it the work was done. They cleaned up, we did final review of completed job, explanation of what to do in case there are questions or issues, invoice, out the door. Quite painless from end to end and I couldn't be more satisfied. Will hire again, absolutely."

"Ahmed is great. Did a great job to upgrade my electrical main panel with very reasonable price. He actually corrected the error made by the AC installer without I asked him to do so. Every professional! Highly recommended"

"Responded immediately to our inquiry. Sent their guy, Israel, for inspection. Since the job was not complicated, we had him complete the job. He was very respectful, told us the problem, proceeded to complete the job. I would highly recommend CA Electrical Group."

"The main complaint I have with Wooding Electric is that the repair was done at a rental property and when I spoke to the gal in the office I told her I wanted an estimate before the work was done. I never got a call to let me know how much the repair would be, and never got a call that the work was done. I had to call my tenant to see if the electrician had been there. I didn't find out how much the repair was going to be until I got the bill in the mail."

Electrical questions, answered by experts

For a 200-amp underground service, you need a minimum of #2/0 American Wire Gauge (AWG) copper or #4/0 AWG aluminum or copper-clad wire. Don’t forget that, at minimum, you’ll need to use a 1 1/2-inch schedule 40 or 80 PVC conduit to successfully run a 200-amp underground service.

The doorbell installation cost depends on which and how many parts you need to replace. A new transformer is the least expensive replacement and falls between $20 and $35, plus the cost of hiring an electrician to install it, which can be between $150 and $250. Replacing your entire doorbell system can cost $250 to $400.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

Yes, one wire is always hot on the 3-way switch, meaning it carries the electricity from the power source to the switch. If you have a 3-wire cable in your home, you have two hot wires, or line wires, coming from the power source. Typically, you’d connect the hot black wire from the power source to the traveler wire and the hot red wire from the power source to the first 3-way switch. For the second 3-way switch, you’d then connect the hot black traveler wire to the switch.

At a minimum, you need an electrician to inspect the house wiring after a fire. The electrician will need to replace damaged or melted wires. If the electrical wiring is old, about 25 years or more, you should rewire the house after a fire. Old wiring can increase the risk of another fire, so replacing the wires is the safest option.
