Standard Operating Procedure
Number 5.3.1.4.6

General

• All cabling paths must be run at least 24" away from electrical cabling or flourescent light fixtures
• EIS Cabling Paths must be exclusive use. No other cabling may share these channels
• All Cabling Paths must meet Local, State, and Federal Fire and Building Codes
• Cabling Paths should not be more than 40% full upon initial installation unless otherwise specified
• Logical Bundles of cables should be secured together using velcro wire-ties as necessary and prudent (e.g. junctions, turns)
• Conduits
  • All conduits or innerduct must be installed with a nylon pulling cord
  • Insulated Bushings must be installed with a nylon pull cord
  • Nylon Pull cord must be installed in all sections of conduit
  • Conduit must be installed independent of other service structures (e.g. other pipes, air-ducts)
• Trays
  • Trays used in all tray applications must be bonded together
  • Trays should be located to allow a minimum of 12" headroom and unobstructed access on all sides of the tray. If an obstruction can not be avoided, the obstruction may not be for more than 36 inches along the tray and must have prior approval by EIS
  • Trays must be installed independent of other service structures (e.g. pipes, air-ducts); they must be mounted directly to the building structure
  • EIS has selected CabloFil brand cable tray products for their ease of use. Any deviation from that selection must be approved by EIS. (see VU Approved Parts list for acceptable part numbers)

Ceiling

• All Ceilings
  • Cabling must be routed in Trays (see FlexTray Brand)
  • Trays should be either wall or ceiling mounted (see FlexTray C bracket); if ceiling hang-mounts are used, the tray must be hung from both sides (mounting fixture should not pentrate the channel)

Floors

• Raised Floor
  • All Cable Paths in Raised Floors must use Trays
  • Trays must be raised a minimum of 1" off the floor
  • Trays should be mounted to floor support system
• Solid (Cement) Floor
  • minimum of 2" PVC or comparable conduit
  • no more than 25% fill upon initial installation
  • pull-string must be installed in all conduits
  • cabling paths may not change directions inside a box
  • 100ft maximum length of continuous piece of conduit (box must be installed after that distance with separate pull-strings for each section)
  • 90 degree maximum turn within a section of conduit
  • Z-turns may not be performed within a continuous piece of conduit
  • the minimum bend radius for conduit must be at least 6 times the inner diameter of the conduit; for conduits greater than 2" diameter, the minimum bend radius must be at least 10 times the inner diameter

Walls

• Cabling must be run exclusively in conduits
• Conduits must stub to the collecting cable path (wire tray, larger conduit)
• Conduits may not be more than 25% full upon initial installation
• Fiber Optic Cabling must be run in separate conduit or in innerduct
• For conduits over 2" in size occupied by fiber-optic cabling, innerducts must be used within conduit
