"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."

"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

Multiple wire sizes are used for residential electrical purposes. While the most common sizes used in homes are 14 and 12 gauge, some appliances, such as stoves, electric water heaters, central air units, etc., may use larger gauge wire to accommodate their larger amperage. Typically, larger appliances require 10-, 8-, or 6-gauge wires.

A full home inspection can cost nearly $350 on average, but inspecting the breaker box specifically is likely to be lower, between $100 and $200. Don’t confuse this service with a basic breaker trip check, which doesn’t take long and is usually billed at $40 to $50 per hour.

If the electrician discovers a serious problem and needs to replace a breaker, it can cost between $100 and $200 in additional expenses. Although rare, replacing the electrical panel typically costs between $500 and $2,000.

Technically, an outdoor outlet can be on the same circuit as an indoor outlet, but it's generally not recommended. Outdoor outlets should ideally be on a dedicated circuit that doesn't share power with other indoor or outdoor outlets. This helps ensure that the outdoor outlets are able to handle the additional electrical load without overloading the circuit. Additionally, outdoor outlets are often exposed to the elements, which can increase the risk of electrical shock and other hazards. If you must have an outdoor outlet on the same circuit as an indoor outlet, be sure that the circuit has the capacity to handle the additional load.

Yes, placing an electrical panel in a bedroom is perfectly acceptable, so long as it meets other space requirements as indicated by OSHA and related agencies. When installed in a bedroom, electricians typically place it in the area directly behind the door swing. This method allows for easy access when conducting electrical panel repairs.

To power the system down, simply turn it off and cut it off from its electricity. That means removing the transformer from the wall plug and taking out the battery that usually sits within the control panel itself. That will disconnect it from power and essentially reset the entire alarm system.
