"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."

"Mr Scott Wooding came to my house, diagnosed the problem with my aging fan, pulled the worn out belt, advised he would order the part and return. Return he did, within 30 minutes. Fixed the fan, looked at some other electrical issues I had and resolved them. Delightful gentleman. Will keep his name in my list of reliable businesses in the area. Thank you Scott"

Electrical questions, answered by experts

Yes, electric fences need power to operate. They are powered by either a battery or an electrical outlet. In heavy snow or extreme rain, or if the power goes out, your electric fence might stop working. Knowing how to test an electric fence is important for figuring out if the fence is still functioning properly.

While washers and dryers do not require a GFCI (ground fault circuit interrupter) outlet to function properly, electrical codes often mandate their use for safety. The National Electrical Code (NEC) requires GFCI protection for all outlets within six feet of a water source. This means a washer and dryer must be plugged into a GFCI outlet if they are installed in locations like a laundry room, utility room, garage, or basement. In other areas without a nearby water source, there is no specific requirement, but using a GFCI outlet is still recommended for extra peace of mind. It is always best to consult your local codes and regulations to ensure compliance and safety.

Yes, you can use a 3/0 AWG wire for a 200 amp service, but only if it is made of copper, as 3/0 copper wire has an allowable ampacity of 225 amps. If you are using aluminum or aluminum copper-clad wire, you need to use at least 4/0 AWG.

Buying a house with aluminum wiring requires careful consideration due to potential fire risks. Ensure a thorough inspection by a licensed electrician to assess the condition and identify necessary safety upgrades—factor in these additional costs when deciding. While it may not be a total deal-breaker, understanding the risks and required maintenance is necessary. Also, you should consult your insurer about coverage for homes with aluminum wiring to know whether the house is insurable.

Overall, heating your home with an oil furnace tends to be less expensive than heating your home with an electric heating system. Oil heating systems stay warm for longer periods of time without drawing a constant electrical current to maintain a temperature. Plus, heating oil systems typically have a longer lifespan and lower price tag than their electrical counterparts, resulting in short- and long-term savings.
