When a single-gang nonmetallic outlet box does not have a clamp or connector, what is the maximum distance permitted between the box and the first strap in a NM cable installation?

In electrical installations, especially when dealing with nonmetallic (NM) cable, there are specific guidelines indicating how far the cable can be run without support. When a single-gang nonmetallic outlet box lacks a clamp or connector, the maximum permissible distance to the first strap is typically defined to ensure both safety and compliance with the National Electrical Code (NEC).

The requirement is set at a maximum distance of 8 inches from the outlet box to the first securing strap. This rule provides adequate support for the cable and prevents any undue stress or potential damage to the wiring, maintaining both safety standards and the integrity of the electrical system. It is essential to follow this guideline to help ensure that the installation remains compliant with electrical codes and minimizes the risk of issues such as cable strain or potential hazards.

This regulation applies to nonmetallic cable installations and is important for electrical professionals to understand to ensure proper installation practices.
