In a NM cable installation without a connector, what is the maximum allowed distance between a single-gang nonmetallic outlet box and the first strap?

In a non-metallic (NM) cable installation, the National Electrical Code (NEC) specifies certain requirements for securing and supporting the cable to ensure it is properly installed and safe to use. For NM cables, there should be a specified maximum distance between the outlet box and the first securing strap.

The correct answer indicates that the maximum distance allowed between a single-gang nonmetallic outlet box and the first strap is 8 inches. This requirement ensures that the cable is adequately supported and does not sag, which can lead to potential damage or electrical hazards. Proper securing of the cable helps to maintain the integrity of the installation and prevents issues such as excessive bending or movement that could create stress on the cable or connections over time.

Other distances are not compliant with the NEC requirements, resulting in inadequate support that could jeopardize the safety and functionality of the electrical system. It's essential for electricians to adhere to these standards for both legality and safety in their installations.
