Size: 14 AWG Through 750 KCMIL – Single Conductor
Conductors: Class B concentric stranded, bare copper conforming to ASTM B-8 and Underwriters’ Laboratories requirements. An opaque mylar tape shall be applied over the conductor to facilitate stripping. Tinned copper is available upon request.
Insulation: Gray EVA Copolymer limited smoke, non-halogen, compound conforming to Underwriters’ Laboratories Standard 44, Subjects 509 and 758, and CSA C22.2 No. 210-2-M90. In addition, the insulation complies with the requirements of TelcordiaTechnologies GR-347-Core. The insulation has a limiting oxygen index (L.O.I.) minimum of 28%. Other colors can be furnished upon request.
Surface Marking: Two sides of the cable shall be printed using an ink of contrasting color and with the following information: “TelcoSafe L1 NON-HAL (SIZE) AWG (OR KCMIL) 600V. RHH OR RHW/ST1 FT4/IEEE1202 (UL) E18321 — A.I.W. CORP. — LL 8825 CSA AWM I A/B 105°C 1000V. W75C, -40°C FT1, FT2 FT4-ST1 (YEAR) (SEQ. FTG. ON 1 SIDE)”
For Sizes 1/0 AWG and larger add, “FOR CT USE” before “(UL)”
For Sizes 8 AWG and larger add, “VW-1″ after “(UL)”
Testing: Physical and electrical tests in accordance with the requirements of UL Standard 44, Subject 509 and 758, and CSA Standard C22.2 No. 210.2-M90 as AWM.
Labels: UL and CSA tags and labels shall be applied to all packages.
Lengths: All put-ups one length only unless agreed to otherwise. Maximum lengths per size will be advised.
Packaging: The ends of the cable shall be capped or taped to prevent the entrance of moisture during shipment or storage.
