2024 OSP-001 PRACTISE TEST
EXAM WITH 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-ANSWERSTrue

cable onto the dock and terminate in a suitable cabinet or enclosure. Run
service drop to each boat slip.

environment using: - CORRECT-ANSWERS• Conduit.
• Cable trays.
• Weatherproof enclosures.
• Other structures suited for harsh, outdoor conditions.
______ cable on docks should be used. - CORRECT-ANSWERSWater-blocked
in marinas the type and size of conduit can be selected following these
guidelines: - CORRECT-ANSWERS• Use rigid nonmetallic conduit wherever
possible.
• Join the sections of rigid conduit with flexible duct where movement of a
dock is probable.
• Use minimum 21 mm (3/4 trade size) conduits for service cables to each
slip.
a common telecommunications conduit within a prefabricated dock section
might be the only available cabling medium: - CORRECT-ANSWERS• In areas
where direct local exchange service and public telephone service are
provided by
,different companies.
• Where CATV is requested.
When an individual boat slip is owned and subleased as a regular
condominium, only the two bordering boat slip owners can legally use a
finger slip, a limited common element.
