When flexibility is not required, AC cable should be stapled or strapped how far from a box?

• A. 1 foot
• B. 2 feet
• C. 3 feet
• D. 4 feet

Answer: (A)

When flexibility is not a requirement for AC cable, the National Electrical Code (NEC) stipulates that the cable must be secured to the structure within 12 inches, or 1 foot, from the outlet box. This distance is intended to ensure that the cable is properly secured and protected from potential damage while also allowing for safe and compliant installation practices.

Stapling or strapping the cable at this distance helps maintain the integrity of the installation, preventing undue stress on the connections and ensuring the cables remain available for their intended use. Proper support is crucial in electrical installations to avoid sagging or other conditions that could lead to safety hazards or damage over time. In areas where flexibility is not necessary, secure support remains essential, and this requirement is efficiently met with the specified distance.
