Specification
XHHW-2 XLP Insulation, 600 Volts

1. SCOPE
1.1 This specification describes single conductor XHHW-2, a general purpose building wire insulated with
crosslinked polyethylene (XLP) intended for lighting and power circuits at 600 volts or less, in residential,
commercial and industrial buildings. The wire may be operated at 90°C maximum continuous conductor temperature
in wet or dry locations and is listed by Underwriters Laboratories for use in accordance with Article 310
of the National Electrical Code.

2. APPLICABLE STANDARDS
2.1 The following standards form a part of this specification to the extent specified herein:
2.1.1 Underwriters Laboratories Standard 44 for Rubber-Insulated Wires and Cables.
2.1.2 ICEA Pub. No. S-95-658, NEMA Pub. No. WC70 for Nonshielded Power Cables Rated 2000 Volts or Less.
2.1.3 Federal Specification J-C-30B.

3. CONDUCTORS
3.1 Conductors shall be Class B stranded annealed uncoated copper per UL Standard 44.

4. SEPARATOR
4.1 A suitable separator over the conductor may be used at the option of the manufacturer.

5. INSULATION
5.1 Each conductor shall be insulated with XLP, a crosslinked polyethylene complying with the physical and electrical requirements of UL Standard 44 for Type XHHW-2.
5.2 The average thickness of insulation, for a given conductor size, shall be as specified in UL Standard 44 for Type XHHW-2. The minimum thickness at any point shall be not less than 90% of the specified average thickness. The insulation shall be applied tightly to the conductor and shall be free-stripping.

6. IDENTIFICATION
6.1 The wire shall be identified by surface marking indicating manufacturer's identification, conductor size and metal, voltage rating, UL Symbol and type designation.

7. TESTS
7.1 Wire shall be tested in accordance with the requirements of UL Standard 44 for Type XHHW-2.

8. LABELS
8.1 The wire shall bear the Underwriters Laboratories label for Type XHHW-2.
