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.

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.

The total cost to install a 120V outlet will depend on the type of outlet you choose, labor costs, and any customizations. Standard 120 volt outlets usually cost $3 to $5 each. But say, for example, you customize your 120V outlets with USB ports, you’ll end up paying a bit more at $13 to $22 per outlet. When it’s all said and done, you can expect to pay around $175 for each new 120V outlet and $125 each for replacement.
