Nonmetallic sheathed cable is not required to be secured to a single-gang, nonmetallic outlet box if the cable is fastened within __________ of the box.

The correct answer is based on the National Electrical Code (NEC) guidelines, which state that nonmetallic sheathed cable does not need to be secured to a single-gang, nonmetallic outlet box if it is fastened within a specific distance from the box. In this case, the requirement specifies that the cable must be secured within 8 inches of the box.

This allows for a bit of flexibility during installation, which helps electricians manage the run and installation of cables without compromising safety or the integrity of the system. If the cable is adequately fastened within that distance, it ensures that there is no strain on the connection point, and it maintains the neatness and organization of the electrical system.

When nonmetallic sheathed cable is installed properly according to these standards, it minimizes the risk of damage to the cable and allows for compliant, efficient wiring practices.
