OSP-001 PRACTISE TEST QUESTIONS AND ANSWERS ALL CORRECT 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). - ANS True placing all of the conduits during the initial conduit system installation is desirable, if not mandatory. *Tr...
