OSP-001 UPDATED Exam Questions and
CORRECT Answers
in areas where future excavation is anticipated, it may be advisable to place the cable at a
greater depth. For example, if road grading that will remove 610 mm (24 in) of dirt is planned
in a particular area, it would be wiser to initially place the cable at 1.2 m (4 ft) versus the
standard
610 mm (24 in). - Correct Answer- True
placing all of the conduits during the initial conduit system installation is desirable,
if not mandatory.
*True
*False - Correct Answer- True
It is not always necessary to build new pathways for cable placement
