Yes, blue wires can be hot wires in the U.S. However, they are less common in residential properties than red and black hot wires. Blue wires are typically used as traveler wires in three-way and four-way switches, as well as ceiling fans. They allow fixtures to be controlled by multiple switches, like when there are switches at the top and bottom of a staircase for the same light.

A weatherhead, the meter base, the breaker box, and a meter panel are all vital components of a working meter riser. If one part of the system is faulty, it could damage other parts, so consider having an electrician inspect the entire unit. The cost to replace the meter panel alone may cost $500 to $1,000, so consider this in your budget for replacing the meter riser.

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.

Simple moves on the same base or within a few feet will not take long, roughly three to four hours. Larger moves onto a new wall or transitioning a box from inside to outside will take 8 to 12 hours to complete. Ask your electrician for a time estimate prior to installation.
