Intermediate Metal Conduit shall be securely fastened within how many feet of each conduit termination?

• A. 4
• B. 6
• C. 3
• D. 10

Answer: (C)

Conduit must be supported close to where it terminates to prevent strain on the connection and keep the box or fitting secure. The NEC requires intermediate metal conduit to be securely fastened within three feet of every conduit termination (such as a box, cabinet, or fitting). After that near-term support, additional supports are placed along the run at intervals up to about 10 feet. So the best answer is three feet, reflecting the requirement to secure EM T right near the termination.
