Yes, electricians must be licensed, certified, and in most cases, insured. Licensing requirements vary by state and local municipality, but most U.S. municipalities require electricians to hold an electrical contractor’s license. It's always a good practice to confirm requirements with your local municipality. Even if licensing is not required in your area, hiring a licensed and experienced electrician often leads to a better end result.

A license is a legal requirement to operate a business and is necessary for pulling project permits. Certifications, on the other hand, are typically voluntary and demonstrate a certain level of expertise. In some cases, a certified electrician may send an apprentice or journeyman to perform the work, but they must operate under a primary electrician who holds the proper license.

Before hiring, you should verify the electrician's license, insurance coverage, and any third-party certifications. You can use Angi’s contractor licensing search to confirm a pro's license status. Additionally, businesses with the “Angi Approved” badge on our platform meet strict criteria, including having the required state and local licenses, passing a background check, and maintaining a high average rating.

To ensure batteries stop charging when they’re full, you’ll need to install a charge controller that determines when the battery is full. Once the battery is fully charged, the charge controller will stop the energy flow or divert the energy to the grid or other appliances. Without a charge controller, the battery may continue to charge, which can lead to less productivity and potential damage.

Yes, tamper-resistant outlets are a safe and effective way to protect children from electrical hazards. They feature a spring-loaded shutter that blocks the outlet slots when not in use, preventing a child from inserting foreign objects. While they are the safest option available, it's important to note that few things can be considered truly 'childproof.' Children may still try to imitate adults by inserting a plug, so constant supervision around any electrical device is recommended. Tamper-resistant outlets are a much safer solution than childproofing covers, which can be removed by children and may pose a choking hazard.

Timers work by using an internal switch to turn power on or off to the cord plugged into it. Just the same way that a light switch turns lights on and off, the timer throws the switch at the programmed times.
