The cable used to interconnect enclosures
on the structure of an irrigation machine
shall be an assembly of stranded, insulated conductors
with nonhygroscopic and nonwicking filler in a core of moisture-and flame-resistant nonmetallic material overlaid with a metallic covering and jacketed with a moisture-, corrosion-, and sunlight-resistant nonmetallic material.
The conductor insulation shall be of a type listed in Table 310.4(A) for an operating temperature of 75°C (167°F) or higher and for use in wet locations. The core insulating material thickness shall not be less than 0.76 mm (30 mils), and the metallic overlay thickness shall be not less than 0.20 mm (8 mils). The jacketing material thickness shall be not less than 1.27 mm (50 mils).
A composite of power, control, and grounding conductors in the cable shall be permitted.
