1 Scope

1.1 These requirements cover multi-conductor, nonintegrally jacketed, distributed generation (DG) cable. The cable is intended for use with specific distributed generation equipment/devices such as photovoltaic modules, inverters, solar trackers, etc. DG Cable is suitable for use between cable trays and utilization.These cables are constructed with or without:

a)    One bare or one or more insulated grounding conductor(s), and/or

b)    One or more twisted pairs used for signal or communication,

1.2 The conductors for these cables are described in NEC types, Section 9.2 and Other insulated conductors, 9.3. Cables are surface marked with the insulated conductor type letters and/or with the temperature and "wet", "dry", or "wet or dry" ratings applicable to the insulation. Cables for direct burial are so marked on the surface. Cables may be surface marked "sun res" or "sunlight resistant". Cables that are surface marked "oil resistant II" have a jacket that is for exposure to oil at temperatures not in excess of 75°C (167°F). Cables that are surface marked "oil resistant I" have a jacket that is for exposure to oil at temperatures not in excess of 60°C (140°F). Each insulated conductor that is oil resistant II, oil resistant I, VW-1, gasoline-resistant, or has another individual conductor use is individually so marked.

1.3 These cables may contain one or more metal shields but do not have a metal sheath or armor. Electrical cables with a metal sheath or armor are covered as Type MC in the Standard for Metal-Clad Cables, UL 1569.
