Installing a new outlet involves permanently modifying a home’s electrical system, so a permit is required in most cases. Additionally, the installation must comply with wiring and placement standards established by the National Electric Code. For example, GFCI outlets are needed in all damp locations, and outlets on dedicated circuits require heavier wiring. The installation process may also involve removing a section of drywall to accommodate a new electrical box or drilling through an exterior wall to install a new outdoor power receptacle. Due to the complexity of each installation, it’s wise for homeowners to consult a licensed professional.
