What does Article 314 say about the installation of boxes in finished walls?

Article 314 of the National Electrical Code addresses the requirements for electrical boxes, including their installation in finished walls. The provision that requires boxes to be flush with the surface of the finished wall ensures that the box does not protrude or is recessed excessively. This is critical for several reasons, including safety and accessibility. When boxes are flush, it helps avoid potential hazards, such as accidental contact with the box's edges and ensures that covers can be properly fitted.

Maintaining a flush installation also supports the aesthetics of the finished wall, providing a clean and uniform appearance. Keeping boxes flush is an accepted standard that takes into consideration not just the functionality of the electrical installation but also how it integrates with the surrounding construction.
