Per their requirements, electrical boxes must be covered with matching electrical box covers. You can’t cover them with drywall, paneling or other wall coverings. The box also needs to have enough space for the conductors inside. Check with your local building inspector before you start any electrical project and obtain the required permits. When you’re done, always have your work inspected for compliance with local codes. This is to ensure that the electrical boxes have been safely installed.
