Provide insulated copper equipment grounding conductor, sized as required
by the rating of the overcurrent device supplying the phase conductors.
3.1.9.4
Cables in [Manholes,] [and] [Handholes,] [and] [Vaults]
**************************************************************************
NOTE: On contracts where existing cables are
recircuited special attention should be given to
changing existing cable identification tags in each
manhole to reflect new circuit numbers.
**************************************************************************
Do not install cables utilizing the shortest route, but route along those
walls providing the longest route and the maximum spare cable lengths. Form
cables to closely parallel walls, not to interfere with duct entrances, and
support on brackets and cable insulators at a maximum of [1220 mm] [450 mm]
[4 feet] [18 inches]. Support cable splices in underground structures by
racks on each side of the splice. Locate splices to prevent cyclic bending
in the spliced sheath. Install cables at middle and bottom of cable racks,
leaving top space open for future cables, except as otherwise indicated for
existing installations. Provide one spare three-insulator rack arm for
each cable rack in each underground structure. In existing manholes,
handholes and vaults where new ducts are to be terminated or where new
cables are to be installed, modify the existing installation of cables,
cable supports and grounding as required for a uniform installation with
cables carefully arranged and supported in the same manner as specified for
new cable. [Provide [_____] cable racks in each underground structure
through which cable is run.]
3.1.9.5
Cable Tags in [Manholes] [and] [Handholes] [and] [Vaults]
Provide cable markers (or tags) as specified in Section 16050N BASIC
ELECTRICAL MATERIALS AND METHODS.
[3.1.9.6
Conductors Installed in Parallel
Conductors shall be grouped such that each conduit of a parallel run
contains 1 Phase A conductor, 1 Phase B conductor, 1 Phase C conductor, and
1 neutral conductor.
