Except as otherwise specified, install underground electrical work as specified in Section 33 71 02.00 20 UNDERGROUND ELECTRICAL DISTRIBUTION and as shown.

a. Where direct burial cable will pass under sidewalks, roads, or other paved areas, the cable shall be placed in minimum 1 inch rigid galvanized steel conduit. Conduit may be installed by jacking or trenching, as approved. When direct burial cable is to be placed in heavy use areas other than paved areas and where the cable may be subject to damage from heavy equipment, the cable shall be placed in minimum 1 inch rigid PVC conduit schedule 80, buried a minimum of 42 inches below the surface.

b. Direct burial cable shall be placed below a minimum 3 inch wide plastic warning tape buried in the same trench or slot. The tape shall be 12 inches above the cable. The warning tape shall be continuously imprinted with the words "WARNING--COMMUNICATION CABLE BELOW" at not more than 4 foot intervals.

c. Transitions from underground cable to aerial cable shall be as specified for CONNECTIONS BETWEEN AERIAL AND UNDERGROUND SYSTEMS in Section 33 71 02.00 20 UNDERGROUND ELECTRICAL DISTRIBUTION.

d. Splices shall be installed in cable boxes. Sufficient cable shall be provided in each splicing location to properly rack and splice the cables, and to provide extra cable for additional splices. Proper strain relief shall be provided. Cable ends shall be protected at all times with end caps except during actual splicing. During the splicing operations, means shall be provided to protect the unspliced portions of the cable from the intrusion of moisture and other foreign matter.

e. For cable installed in ducts and conduit, a cable feeder guide shall be used between the cable reel and the face of the duct and

SECTION 27 33 31.00 10 Page 7 conduit to protect the cable and guide it into the duct and conduit as it is played off the reel. As the cable is played off the reel, it shall be inspected for jacket defects. Cable shall not be kinked or crushed during installation. A pulling eye shall be attached to the cable and used to pull the cable through the duct and conduit system.

Cable shall be hand fed and guided through each manhole. As the cable is played off the reel into the cable feeder guide, it shall be sufficiently lubricated with a type of lubricant recommended by the cable manufacturer. Where the cable is pulled through a manhole, additional lubricant shall be applied at intermediate manholes.

Dynamometers or load-cell instruments shall be used to ensure that the pulling line tension does not exceed the installation tension value specified by the cable manufacturer. The mechanical stress placed upon a cable during installation shall not be such that the cable is twisted or stretched.
