GENERAL

This category covers thermoset-insulated wire and cable (tabulated below) which is flame retardant and rated 600 V, except for Types RHH, RHW and RHW-2 which may be rated 2000 V. The voltage rating is marked on the outer surface of the wire or cable.

PRODUCT MARKINGS

RHW — Indicates a single conductor having a thermoset insulation, with or without a nonmetallic covering, rated 75°C dry, 75°C wet.

RHW-2 — Indicates a single conductor with the same description as Type RHW, except that it is rated 90°C dry, 90°C wet.

RHH — Indicates a single conductor with the same description as Type RHW, except that it is rated 90°C dry only.

XHH — Indicates a single conductor having a cross-linked synthetic polymer insulation with no overall covering provided, rated 90°C dry.

XHHW — Indicates a single conductor with the same description as Type XHH, except that it is rated 90°C dry, 75°C wet.

XHHW-2 — Indicates a single conductor with the same description as Type XHH, except that it is rated 90°C dry, 90°C wet.

SA — Indicates a single conductor having thermosetting silicone rubber insulation and a nonmetallic covering rated 90°C dry, general use, 200°C dry, special applications.

SIS — Indicates a single conductor having thermosetting insulation with no overall covering provided rated 90°C dry, for switchboard wiring only.

D — Used as a suffix indicating a twin wire having two insulated conductors laid parallel under an outer nonmetallic covering.

M — Used as a suffix indicating a cable having two or more insulated single conductors twisted together under an outer nonmetallic covering.

This wire, in sizes mentioned below, may employ copper, aluminum, or copper-clad aluminum conductors. Wire with copper-clad aluminum conductors is surface printed "Cu-Clad Al" or "AL (CU-CLAD)." Wire with aluminum conductors is surface printed "AL."

In addition to the required AWG or kcmil size, the metric equivalent may be marked on the wire, e.g. "6 AWG (13.3 MM2)" or "13.3 MM2 (6 AWG)."

Types RHH, RHW, RHW-2, XHH, XHHW, XHHW-2 and SA are certified in sizes 14 AWG through 2000 kcmil copper, and 12 AWG through 2000 kcmil aluminum or copper-clad aluminum. Type SIS is certified in sizes 14 through 4/0 AWG copper, and 12 through 4/0 AWG aluminum or copper-clad aluminum.

Wire and cable employing compact-stranded copper conductors is so identified directly following the conductor size wherever it appears (surface, tag, carton or reel) by "compact copper." The abbreviations "CMPCT" and "CU" may be used for compact and copper, respectively.

Tags, reels and cartons for products employing compact-stranded copper conductors have the marking: "Terminate with connectors identified for use with compact-stranded copper conductors."

Wire bearing multiple type designations is suitable for the temperature associated with each use. For example, a wire marked "RHH or RHW" is suitable for 90°C in dry locations, and 75°C in wet locations.

Wire marked "GR I" or "GR II" has been tested at 23°C when immersed in gasoline and in oil at 60°C and 75°C, respectively. Wire marked "PR I" or "PR II" has been tested for immersion in oil at 60°C and 75°C, respectively.

Wire and cable marked "CT" complies with a Vertical-Tray Flame Test. Wire and cable marked "SR" complies with an artificial weathering test. The "CT" marking, with or without the "SR" marking, pertains to single conductor sizes 4 through 1 AWG for grounding conductors only, single conductor sizes 1/0 AWG and larger, and all sizes of multiconductor Types RHH, RHW, RHW-2, XHH, XHHW and XHHW-2.

Wire marked "VW-1" complies with a Vertical Flame Test; all others comply with a Horizontal Flame Test.

Wire that complies with the Limited Smoke Test requirements specified in ANSI/UL 1685, "Vertical-Tray Fire-Propagation and Smoke-Release Test for Electrical and Optical-Fiber Cables," is surface marked "ST1."

Wire and cable marked "-40 C" complies with a cold impact test conducted at that temperature. This does not necessarily mean that the cable can be easily installed at that temperature. Different installation conditions and configurations require that care be taken when installing cable at low temperatures.

Wire and cable may be surface marked with the suffix "-HF" when it has been determined that all of the combustible materials used in the construction (e.g., insulation, fillers, jackets) are halogen-free in accordance with UL 2885, "Outline of Investigation for Acid Gas, Acidity and Conductivity of Combusted Materials and Assessment of Halogens."

Wire and cable that meets the requirements for "HF" indicated above and that also complies with the requirements for low smoke when tested in accordance with IEC 61034-2, "Measurement of Smoke Density of Cables Burning Under Defined Conditions - Part 2: Test Procedure and Requirements," may be surface marked with the suffix "-LSHF."

Submersible Water Pump Cable — Indicates multiconductor cable in which two, three or four Type RHW, RHW-2, XHHW or XHHW-2 conductors are provided in a flat or twisted assembly. The cable is certified in sizes from 14 AWG through 500 kcmil copper, and from 12 AWG through 500 kcmil aluminum or copper-clad aluminum. The cable is tag marked, "For use within the well casing for wiring deep-well water pumps where the cable is not subject to repetitive handling caused by frequent servicing of the pump units." The surface of the wire may also be marked "Pump Cable." The cable has not been investigated for direct burial in the earth unless the single conductors carry an additional "Type USE" or "Type USE-2" marking.

REQUIREMENTS

The basic standard used to investigate products in this category is ANSI/UL 44, "Thermoset-Insulated Wires and Cables."

UL MARK

The Certification Mark of UL on the attached tag, reel, or on the smallest unit container in which the product is packaged, with or without the UL symbol on the product, is the only method provided by UL to identify products manufactured under its Certification and Follow-Up Service. The Certification Mark for these products includes the UL symbol, the words "CERTIFIED" and "SAFETY," the geographic identifier(s), and a file number.

Alternate UL Mark

The Listing Mark of UL on the attached tag, the reel, or the smallest unit container in which the product is packaged, with or without the UL symbol on the product, is the only method provided by UL to identify products manufactured under its Listing and Follow-Up Service. The Listing Mark for these products includes the UL symbol (as illustrated in the Introduction of this Directory) together with the word "LISTED," a control number, and the product name as appropriate: Thermoset-insulated wire that contains copper or copper-clad aluminum conductors has the product name "Insulated Wire"; thermoset-insulated wire that contains aluminum conductors has the product name "Insulated Aluminum Wire."
