Which section of the NEC® allows for the installation of nonmetallic outlet and device boxes with nonmetallic sheathed cable?

The installation of nonmetallic outlet and device boxes with nonmetallic sheathed cable is governed by specific requirements in the National Electrical Code (NEC). In this case, the appropriate section would be 314.3. This section outlines the general requirements and conditions under which nonmetallic outlet and device boxes can be used, particularly emphasizing their compatibility with nonmetallic sheathed cable.

Nonmetallic sheathed cable, commonly known as NM or Romex, is favored in residential and light commercial applications due to its ease of installation and cost-effectiveness. Section 314.3 details the permissible applications and includes specific conditions that must be met for the use of these boxes, ensuring compliance with safety and effective functionality. This ensures that installations not only follow code but also maintain the integrity of the electrical system.

The other sections mentioned address various aspects of outlet and device box installations but do not specifically pertain to the use of nonmetallic outlet boxes with nonmetallic sheathed cable, making 314.3 the correct reference for this scenario.
