C. 2.2 1 CORD: Types STOO, SOW-A, and SOOW-A portable cords shall be I suitable for wiring control devices on industrial equipment, such as I limit and pressure switches, solenoid valves, and similar apparatus 1 operated at nominal 115 Vat. The cord is also

9、 specified for 1 extension cords and lamps and related services (see Standard EW2). 2.3 I POWER CABLE: Power cable shall be used for wiring to motors and other apparatus operated at 240 and 480 Vat. The cable shall be available in conductor sizes AWG #14 thru #2. 3. REQUIREMENTS: 3.1 INSULATION AND

10、JACKET MATERIALS: The conductor insulation and the jacket shall consist of thermoplastic or thermoset material having water-, chemical- and oil- resistant properties. The jacket material shall comply with all requirements for Class II material as specified in UL 62. Rubber and rubber compounds are n

11、ot acceptable for insulation or jacket materials. 3.1.2 I Individual conductor insulation shall comply with UL 62 for I Extra Hard Service Cords. The thickness shall not be less than I specified in NEC Table 400-4. 3.2 COLOR: 3.2.1 I I I The insulation on each conductor of portable cord shall be per

12、manently colored per the Control Cable Conductor Color Code, Method 1 - Table K-l, and the color shall extend throughout the length and thickness of the material as follows: Three-Conductor - One each black, white, and green. Five-Conductor - One each black, white, red, orange, and green. I The gree

13、n insulation may include yellow tracer stripe(s).

14、ut the length and thickness of the material as follows: Three-Conductor - One black, one white, and one red. The three grounding wires may be bare or have green insulation. I The green insulation may include yellow tracer stripe(s). 3.3 FILLERS AND BINDERS: 3.3.1 I Non-hygroscopic and non-wicking ma

15、terials shall be provided I where fillers are required. 3.3.2 1 I A non-wicking, full-serve binder shall be applied over the assembled conductors and shall consist of tape, braid, or a wrap of multiple strands of thread or a combination thereof. 3.4 CONDUCTORS: 3.4.1 1 I I Conductors shall be strand

16、ed copper, Class K or M, soft annealed per ASTM B-174. Stranding shall not be less than specified in the following table: Conductor Size AWG No. Number of Strands 18 16 16 26 14 41 12 65 10 105 8 168 6 266 4 420 2 665 Individual strand size for all conductors is AWG #30.
