PART 3 - EXECUTION

3.1 EXAMINATION

A. Examine raceways, ductbanks, manholes, cable vaults and cable trays to receive medium-voltage cables for compliance with requirements for installation tolerances and other conditions affecting performance of cables. Do not proceed with installation until unsatisfactory conditions have been corrected.

02/16/17 2:38 PM 260513 - 7

3.2 INSTALLATION

A. General:

1. Determine and procure correct length of cable from field measurements. Do not determine the length of cable from dimensional Drawings.

2. Do not install cables below manufacturer’s minimum recommended installation temperatures.

When installing cables in low temperatures, pre-warm cables per manufacturer’s installation recommendations.

3. Install cabling in raceway systems, as indicated and as specified except where exposed cabling is indicated or specified. Install cabling only in completed raceway systems and when systems are protected from the weather. Install conductors continuous, without splices, between equipment, where possible unless otherwise noted.

4. All cable ends shall be sealed to prevent the entrance of moisture into the insulation during installation.

5. Continuously lubricate all non-armored cables of the larger sizes at the pull-in point of conduit systems with a lubricating compound compatible with conductor insulation or jacket.

6. Install conductors in such a manner that the bending radius of any cable is not less than the minimum recommended by ICEA, AEIC, or the manufacturer. In pulling cables, do not exceed the manufacturer’s recommended values for maximum pulling tension using woven wire grips or pulling eyes. When cables are pulled by means of a powered winch, be particularly careful not to exceed cable tension limits.

7. Provide sufficient slack for expansion and contraction of the cables. Provide maple cable clamps and “Unistrut” to support cable on walls. Support cables at not more than 4 ft (1.2 m) intervals.

8. Where cables are exposed in manholes, cable vaults and as noted on the Drawings, fireproof cables as specified for exposed cables.

9. Connect all cabling to equipment such that phasing is A-B-C left to right, top to bottom and front to back, where possible, and permanently identify phasing on the structure or housing adjacent to the bus. Phase identification A-B-C is equivalent to transformer phase identification

X1-X2-X3 and H1-H2-H3. Identify individual conductors as to phase connection A, B, C by means of wire labels, at each splice and termination. Proper phasing shall be verified before final termination and energizing.

B. In Underground Duct Systems:

1. Brush and swab the duct line before pulling cables. Use flexible cable Feeders of an appropriate size to lead the cable from the reel into the duct mouth. In manholes and handholes, install cables on cable rack insulators. In passing cables through manholes and handholes, take care to void crossovers so that each cable is accessible when placed on racks; and where feasible, install each cable in the duct in the same relative position throughout the underground system, unless otherwise required or indicated. Install cable so that spare ducts are accessible for use in the future.

2. All cables shall be pulled from manhole to manhole (not through the manhole). All cables shall be wrapped a minimum of 360 degrees around the interior of each manhole.

3. Fireproof each cable at exposed locations in manholes and cable vaults as follows:

260513 - 8 02/16/17 2:38 PM

a. Install not less than 4 layers of arc-proofing tape, two layers half-lapped, in one direction.

Terminate fireproofing approximately 1/2 inch (12.7 mm) from the duct face to permit inspection of the cable at the duct entrance and to prevent the fireproofing from interfering with the expansion and contraction of the cable.

b. In applying tape, snug the tape by twisting the tape with the hand. Where steep inclines are caused by changes in cable diameters, such as at splices, apply tape in a stair-step manner by increasing the lapping of the tape as required to maintain a minimum thickness of 4 layers. Increase lapping around cable bends to avoid decreasing the thickness below minimum on the outside of the cable bend.

c. Band the arc-proofing tape with 1/2 inch (12.7 mm) wide pressure-sensitive fiber glass cloth banding tape, at intervals not exceeding 12 inch (305 mm) on centers. Construct bands of not less than six turns of banding tape so applied that not more than three turns are in contact with the elastomer backing of the arc-proofing tape.

C. Splices and Terminations:

1. Do not install splice kits or stress cones below manufacturer’s minimum recommended installation temperatures.

2. Splice and terminate conductors with connectors and lugs as specified for the specific size and type of conductor. Terminate shielded cables with stress cones. Continue shields through splices and ground shields at splices and at terminations. Do not splice cables except where cable lengths are limited by maximum reel capacity or anticipated pulling tension. Do not splice direct burial cable underground. Indent all compression type connectors and lugs with tools as recommended by the connector or lug manufacturer.

3. Do not open cable prior to splicing or terminating unless unavoidable, and do not make splices or terminations if exposed to damp or inclement weather, except when prior approval has been obtained from the Architect and a cable splicer’s tent or other approved means of protection is employed. Pull the cables and overlap sufficiently at cable ends to provide undamaged cable for splicing and/or termination. Pull the cables to be spliced so that the ends overlap at least 5 ft

(1.5 m). Train or rack cables into their final positions as shown on Drawings before cutting any cable. Cut cables to be spliced so that they butt squarely at the centerline of the splice. Once a cable is opened, proceed with the work immediately and continue uninterrupted until the splice or termination is completed, including any sealing or resealing required.

4. Thoroughly clean conductor ends before connectors or lugs are applied. Whenever copper lugs are terminated on aluminum bus, use a Belleville washer and two tin or cadmium plated washers, one on each side, in combination with aluminum joint compound on all contacting surfaces. Tighten bolts until Belleville washer is flat.

5. Insulate splices and terminations with materials in packaged kits as specified. Follow instructions of the cable manufacturer for the work. Install rainshields for outdoor taped terminations. Install potheads, preformed stress relief terminators for outdoor terminations on poles or structures. Install armor terminators for armored cable terminations at equipment.

Where splices are required in armored cables, use approved splicing sleeves and locate sleeves outside of and adjacent to the tray, not in the tray. Provide separate supports for same. Support all splices in non-armored cables in manholes adjacent to the splice, not on the splice.

02/16/17 2:38 PM 260513 - 9

6. Provide a complete installation for pole mounted “Capnut terminations” include all components supports, etc. as required for a complete installation including, the connectors, body, insulators, terminations, entrance fittings, insulating material etc. Provide high strength dielectric strength filler material for use in termination units. Compound shall be suitable for use with the conductor type specified. Installation of the termination unit and associated compounds shall be in accordance with the manufacturer’s installation documentation.

D. Cable Identification:

1. Identify cables at entering and leaving location in manholes, cable vaults, and pullboxes at terminations by means of a plastic laminate tags, 2 inch (50.8 mm) diameter, laminate shall be white surface and black core. Fasten tags around the cable with non-metallic waterproof cord.

2. Designate source and load, or feeder or cable identification on tags.

3.3 TESTING

A. Before cables are energized, cables and accessories shall be tested per Section 267000, “Electrical

Systems Testing”.

PART 3 - EXECUTION

3.1 INSTALLATION

A. General:

1. Install wiring in accordance with NEC or per any other codes that take precedence.

2. Coordinate the specified work with adjacent construction in clearing equipment and inserts by at least 6 inch (152 mm). If the indicated location of any electrical outlet is concealed or covered by adjacent construction, install the outlet to clear the interference and extend conduit and wiring to the location shown on Drawings.

3. Install wiring in raceway systems, as indicated and as specified, except where exposed wiring is indicated or specified. Install wiring only in completed raceway systems and when systems are protected from the weather.

4. Install conductors continuous, without splices, between equipment, where possible.

Where splices are required, make up splices in boxes; do not use fittings for same.

5. Install phase and neutral conductors of each branch or feeder circuit in a single conduit except where paralleling circuits are indicated. Install paralleling circuits of identical make-up and length as the paralleled circuit, and terminate conductors at the same location, mechanically and electrically, at both ends, to ensure equal division of the total current between conductors.

6. Run a separate neutral wire for each single phase load. The neutral wire shall not be shared between phases in 3 phase, 4 wire system, and in the case of 120/240 volt AC system, the neutral shall not be shared between the lines.

7. No more than six (6) current carrying conductors shall be installed in a single conduit.

For this project, neutrals are considered current carrying conductors.

8. Run an insulated green ground conductor in all conduits.

9. Continuously lubricate cables at the pull-in point of conduit systems with an approved compound compatible with conductor insulation or jacket.

10. Install conductors in such a manner that the bending radius of any wire or cable is not less than the minimum recommended by ICEA and/or the manufacturer. Do not exceed manufacturer’s recommended values for maximum pulling tension applied to any wire or cable.

260519 - 8 02/16/17 2:39PM

11. Support vertical riser cables over #4 AWG at top and at any intermediate terminations of conduit with cable supports.

12. Connect all power wiring to equipment, such that phasing shall be A-B-C-N left to right, top to bottom and front to back, where possible, and permanently identify phasing on the structure or housing adjacent to bus. Phase identification A-B-C is equivalent to transformer phase identification X1-X2-X3 and H1-H2-H3.

13. Connect phasing wiring to all 3 phase receptacles to insure the same phase rotation in all receptacles with interchangeable plugs.

14. For accessories that require special tools for installation, use such special tools recommended by the respective manufacturer, and in accordance with the established practice and the recommendation of the manufacturer.

15. Use manufacturer approved pulling compound or lubricant where necessary. Compound used must not deteriorate conductor or insulation. Do not exceed manufacturer’s recommended maximum pulling tensions and sidewall pressure values.

B. Type “MC” Cables:

1. Installation of NEC Type “MC” cables shall conform to NEC, local, state and National

Codes. In general, install Type “MC” cables in all locations except underground, exposed locations below 6 ft (1.8 m) AFF, in concrete, mechanical and electrical equipment spaces below 6 ft (1.8 m) AFF or hazardous areas. Support cables at 5 ft

(1.5 m) interval, maximum and within 12 inch (305 mm) of junction or outlet boxes. The bending radius of the cable shall be 8 times the outer diameter of the cable, minimum or in accordance with manufacturer recommendation, whichever is larger. All fittings and connectors shall be approved for Type “MC” cables and shall be in accordance with manufacturer recommendations.

C. Conductor Color Coding:

1. Provide phase specific color coding on three phase feeders and three phase branch circuits as indicated below.

480/277 Volt System 208/120 Volt System 240/120 Volt System

Phase A Brown Black Black

Phase B Orange Red Red

Phase C Yellow Blue Blue

Neutral Gray White White

Ground Green Green Green

Isolated

Ground

Green w/ Yellow Strip or Tape

Green w/ Yellow Strip or Tape

Green w/ Yellow Strip or Tape

2. Single phase feeders and branch circuits shall utilize any of the listed colors for the given voltage class for live or neutral conductors respectively. Single phase line-line feeders and branch circuits shall not utilize the same color.

3. Phase specific color coding shall be either factory applied within the wire insulation or applied with tape to the cables at all accessible locations.

02/16/17 2:39PM 260519 - 9

D. Conductor Labeling:

1. Provide unique labeling of all branch circuit conductors and associated neutral conductors. (The conductor labeling should not be panel circuit number specific to allow balancing of panel loads.) In all terminal cabinets, panelboards, distribution, control and load centers, pull boxes and wherever conduit run is broken. Mark the white marking strip of all control terminal blocks with the same identification as the connecting wire in permanent black ink.

2. All conductors shall be tagged at their point of origin, in all junction and pull boxes and at their point of termination.

E. Feeders:

1. The bending radius of the cable shall be 5 times the cable diameter, minimum, and hickeys shall be used for bending the cable.

2. Where single conductor cables are used, they shall be run close together with sheathing touching throughout the lengths of the run. Parallel runs of single conductor cables shall be phased out in groups and the groups shall be spaced at least two cable diameters apart, minimum.

3. The cable shall be terminated with glands and seals approved for the application and installed per manufacturer’s recommendation. Use the tools designed for the purpose to prepare and install the cable.

4. The cable may be spliced in a junction box. Termination shall be installed on the ends of cable entering the box, and the box shall be accessible. All fire rated glands shall be installed by the manufacturer’s representative.

F. In Underground Duct Systems: Brush and swab the duct line before pulling cable. When installing cables of large sizes, use flexible cable feeders of an appropriate size to lead the cable from the reel into the duct mouth. In manholes, install power cables exposed on cable racks, and control and special system wiring in rigid steel conduit systems. In passing cables through manholes, take care to avoid crossovers so that each cable is accessible when placed on racks, and where feasible, install each cable in the duct in the same relative position throughout the underground system, unless otherwise required or indicated. Install cables so that spare ducts are accessible for use in the future.

G. Fill the remainder of the trench, and carefully tamp, with materials and compaction methods to suit project conditions per applicable Sections of Division 31.

H. Splices and Terminations:

1. Splice and terminate conductors with connectors and lugs as specified for the specific size and type of conductor. Do not splice armored cable except where cable lengths are limited by reel capacity. Do not splice direct burial cable underground, unless specifically specified in the documents. Indent all compression type connectors and lugs with tools as recommended by the connector or lug manufacturer.

2. Thoroughly clean wire ends before connectors or lugs are applied.

260519 - 10 02/16/17 2:39PM

3. Whenever copper lugs are terminated on aluminum bus, use a Belleville washer and two tin or cadmium plated washers, one in each side in combination with aluminum joint compound on all contacting surfaces. Tighten bolts until Belleville washer is flat.

4. Insulate all bare surfaces of conductors with a minimum of four layers (half lap in two directions) of electrical insulating tape. Tape joints in outlet and junction boxes in such manner and thickness that the insulating value of the joint or splice will be at least equal to the insulating value of the conductor to which it is applied. On larger splices and terminals, build up connection with electrical insulating putty before applying tape, to eliminate both sharp edges and voids.

5. Terminate all armored cables at equipment with an approved type of armored cable terminator and terminate cable ground conductors on equipment ground bus. Where splices are required in armored cables, use approved splicing sleeves. Locate splicing sleeve outside of and adjacent to the tray, not in the tray.

6. Twist-on pigtail connectors shall be used in all locations for #10 AWG (5.261 mm ) and smaller not subject to movement and vibration. They shall not be used for connection to rotating equipment. Crimp pigtail connectors shall be used for #10 AWG (5.261 mm and smaller for connections to rotating equipment and where wiring is subject to movement and vibration.

7. Provide junction boxes and reduce conductor sizes to accommodate equipment lugs when wire sizing has been increased to compensate for voltage drop or when using wire taps.

8. Tighten electrical connectors and terminals, including screws and bolts, in accordance with manufacturer’s published torque values, or where manufacturer does not indicate torque requirements, per UL 486A.

I. Splicing for Underground Wires:

1. Splices of underground wires shall only be made in handholes, manholes or junction boxes, unless specifically noted in the documents for a specific location.

2. Splices shall be resin encapsulated 82A Series in line type of splice using a long barrel double trimmed connector rated for the conductor’s ampacity of the wire. Each pair of wires per Phase shall be spliced independently. Multi conductor multi-phase encapsulated splices shall not be permitted.

3. For wye type splices use resin encapsulated 82B Series. Splice with compression tap connectors rated for the ampacity of the conductors. “C” type or “H” type tap may be used.

4. Heat shrinks or taped splices are not permitted for use on underground wires in below grade applications.

J. Cable Identification:

1. Identify cable groups and conduit at entering and leaving locations in manholes and handholes by means of plastic phenolic laminated white surface and black core. Fasten tags around the cable group or conduit with #12 AWG (3.31 mm ) copper wire.

2. Identify cables in cable tray at intervals of 40 ft (12.2 m), at each side of walls, and at terminations and splices by means of strip aluminum with raised letters.

3. Designate source and load, or feeder or cable identification on tags. Submit identification for the approval of the Architect.
