RCDD-001 Exam - Question 36


Cables are installed in a ceiling in a straight line. The ceiling run is 60 m (200 ft) in length. What is the MINIMUM number of J-hooks required to support the cables?

Show Answer
Correct Answer: C

Standard cable support guidelines often recommend placing J-hooks at intervals of approximately 1.5 meters (around 5 feet). For a 60-meter (200-foot) run, dividing 60 meters by 1.5 meters results in 40. Thus, the minimum number of J-hooks required to support the 60-meter ceiling cable run is 40.
