4. Construction
4.1 Conductors
Conductors shall be Class B or C concentric stranded, soft or annealed tinned copper in accordance with ASTM B-8 and B-33. Type XHHW-2 conductors are typical of the approved type.
4.2 Insulation
Each conductor shall be insulated with FR-EPR or EPR meeting the flame test requirements of ICEA S-95-658. The average thickness shall be 25 mils for No. 16 AWG, 30 mils for Nos. 14 - 10 AWG, and 45 mils for Nos. 8 - 2 AWG. The minimum thickness at any point shall not be less than 90 percent of the specified average thickness.
4.3 Circuit Identification
The insulation for conductors No. 10 AWG and smaller shall be color coded in accordance with ICEA S-73-532 Appendix E, E.3.1 Method 1, Table E-2 (see excerpt below, shown as Table 1). The insulation for conductors No. 8 AWG and larger shall be color coded in accordance with ICEA S-73-532 Appendix E., E3.3 Method 3, Table E-2, black insulation with white printing.
5. Testing
Individual conductors and completed cables shall be tested in accordance with all applicable requirements of ICEA S-73-532 and ICEA S-95-658. Cables shall be capable of passing the vertical tray flame test requirements of IEEE Standard 383.
6. Shipment and Reels
6.1 Packaging and Sealing
6.1.1 Cable shall be supplied in one continuous length for each reel. Cable length per reel shall be as specified in Table 2, shown below.
6.1.2 Each end of the cable shall be firmly and properly secured to the reel. Care shall be taken to prevent looseness of reeled cable. The cable end attached through the interior of the reel shall be fastened in such a manner that it remains attached as the cable is dispensed from the reel and does not interfere with other reels or waste cable.
6.1.3 Watertight seals shall be applied to all cable ends to prevent entry of moisture during transit and outside storage. All reels shall have Level 2 protection over the outer layer of the cable in accordance with NEMA WC 26-2000, Section 4.1.
6.2 Reels
Unless otherwise stated on the Special Provision Sheet all reels shall:
- Be standard non-returnable wood conforming to NEMA WC 26.
- Be free of damaging protrusions such as nails, staples, etc.
- Have minimum drum diameters as specified in NEMA WC26.
- Have dimensions as shown below in Table 2.
