PART 3 - EXECUTION

3.1 INSTALLATION

A. Wires shall be installed in conduit or in another approved raceway, where shown. Where a wire run is above a suspended ceiling, its conduit or raceway shall be tied up or clamped to independent supports and not left to sit on top of the ceiling panels.

1. Conduit Verification: Verify that conduit has been installed, de-burred and properly joined, routed and terminated prior to pulling of cables.

2. Wire Pulling: Apply a chemically inert conduit lubricant to wire and cable prior to pulling. Do not subject wire and cable to tension greater than recommended by the manufacturer.

3. Wire Routing: Secure wire and cable runs vertically in conduit for continuous distances greater than thirty (30) feet at the vertical run terminations. Non-coaxial cables shall be secured by screw-flange nylon cable ties or similar devices. Symmetrical clamping devices with split, circular or other wire conforming, non-metallic bushings shall be provided for other cables.

4. Verification of Continuity: After installation, and before termination, wiring shall be checked and tested to insure there are no grounds, opens, or shorts on any conductors or shields. In addition, wiring between buildings or underground and coax cables shall have insulation tested with a megohmeter and a reading of greater than 20 megohms shall be required to successfully complete the test.

B. Aerial Cabling

1. Where shown on the plans, new cabling shall use new aerial cable routing system, including but not limited to new supports, messenger systems, grounding systems, and building entry points.

2. Contractor shall be responsible for providing additional support, grounding, and other elements of the aerial cable system as may be required by the codes and standards.

C. Splicing

1. Run wires continuously from termination to termination without splices.

2. Splices at certain junction box locations may be allowed at the discretion of the Owner and the Engineer. Locations which may require spliced wires should first be established with the Owner and Engineer. Contractor shall obtain written approval before proceeding with splices.

3. If splices are required and approved, the wire shall be joined with solder, then enclosed in heat-shrink tubing and protected in an approved manner so as to provide mechanical and electrical integrity. Wire nuts and/or electrical tape connections shall not be acceptable. Final connections shall be made at terminal boards with full tagging, labeling and documentation.

D. Water Protection: Water-resistant protection shall be continuous throughout the cable in surface conduit, poles, in-slab pull-boxes, in-slab conduit, and underground conduit and pull-boxes, and in any areas subject to moisture and/or water infiltration.

1. Splices/Junctions: Provide water-proof protection of splices and junctions in exposed areas, in surface conduit and boxes, in-slab conduit and pull-boxes, underground conduit, and underground pull-boxes, to prevent the entry of moisture or water into cables, splices or connections.

2. Cable Entries: Provide water-blocking sealants at conduit entries into pull-boxes, junction boxes, back-boxes, cabinets, etc., to prevent the entry of moisture or water into the conduit and cable system.

E. After installation, and before termination, wiring shall be checked and tested to insure there are no grounds, opens, or shorts on any conductors or shields. In addition, wiring between buildings or underground and coax cables shall have insulation tested with a megohmeter and a reading of greater than 20 megohms shall be required to successfully complete the test.

F. Boxes: Provide a box loop for wire and cable routed through pull boxes or distribution panels.

Cable loops and bends shall not be at a radius less than that recommended by the manufacturer.

Coordinate pull box size as necessary to accommodate this requirement.

G. Wire Labeling: Identify wire and cable clearly with permanent labels wrapped around the full circumference within one-inch of each connection. Locate the label so that it is visible, and so that wire does not need to be undressed or disassembled for clarity. Correlate the label with the number designated on the associated Shop or Field Drawings. Assign wire or cable designations consistently throughout a given system. Each wire or cable shall carry the same labeled designation over its entire run, regardless of intermediate terminations.

H. Wire Lacing and Dressing: Dress, lace, tie or harness wire and cable vertically, horizontally and at right angles to the enclosure surfaces to prevent mechanical stress on electrical connections as required herein and in accordance with accepted professional practice. No wire or cable shall be supported by a connection point. Use the specified cable management guides within enclosures and cabinets to ensure a neat wiring scheme.

I. Non-Coaxial Terminations: Make non-coaxial connections and splices to screw-connection terminal blocks with insulated crimp-type spade lugs or under terminal block pressure plates. Size terminal blocks and lugs properly to assure high electrical integrity. Connect only one (1) wire per spade lug and not more than two (2) lugs per screw terminal.

J. Shielded Cables: Shielded cables shall be insulated. Do not permit shields to contact conduit, raceway, boxes, terminal cabinets or equipment enclosures. Tin terminated shield drain wires and insulate with heat shrinkable tubing.

K. Cable and Wire Pulling

1. Contractor shall submit the following information for each segment of cable to be installed:

a. Cable pulling layout including distances, bends, and tension calculations for each section of the installation. The calculation submittals shall bear the printed name, date, and signature of the person who is responsible for the calculations.

b. Pulling equipment and tension monitoring devices. Calibration records for all monitoring equipment shall be submitted.

c. Chronological plan for installing cable, including estimated time for each pull and plan for protecting cable on reel, in slack loops during installation, and after the pull has been completed.

2. For pulling calculations, consideration shall be given to the following parameters - fill, coefficient of friction, clearance, configuration, jam ratio of the cables and conduit, weight correction factor, bend radii, maximum allowable tension, sidewall load, the method of attaching the conductors to the pulling equipment, and weight of the cables. These factors shall be calculated for each pull. The Contractor shall not exceed the manufacturer recommended values of sidewall pressure, pulling strain on conductors or sheath, limits of pulling device, and pulling tension.

3. The Contractor shall not exceed the following guidelines:

a. The maximum pulling strain on the cable with a pulling eye attached to the conductors is a function of the conductor area as follows: TM = 0.008 x n x CM., where TM = Maximum tension (lbs), n = number of conductors, CM = area of each conductor (circular mils).

b. When a basket-weave grip is used in lieu of a pulling eye, the maximum tension shall not exceed the value calculated for the…
