Important: The National Electrical Code (NEC) and local building codes regulate the types of electrical boxes that can be used in specific applications, as well as the manner of installation. These codes require that electrical boxes not be covered with drywall, paneling or other wall coverings, but with electrical box covers that can be matched to all boxes. Check with your local building inspector before you start any electrical project and be sure to obtain required permits. When your work is complete, always have it inspected for compliance with local codes to ensure that it has been safely installed.
