[NESC 350F, p. 263] (Change) Change paragraph F to read:
The appropriate identification symbol shown in Fig 350-1 shall be indented or embossed in the outermost cable jacket at a spacing of not more than 1m (40 in). The symbol may be separate or sequentially combined with other data, or symbols, or both, printed on the jacket. If the symbol is sequentially combined, it shall be separated as indicated in Fig 350-1. If optional supplemental striping is used, only supply cables or non-metallic duct containing or intended to contain supply cables may have three equally separated longitudinal red stripes.
This rule applies to cable installed on or after January 1, 1996.
Exception 1: Cables with jackets that cannot be effectively marked in accordance with Rules 350F need not be marked.
Exception 2: Unmarked cable from stock existing prior to 1 January 1996 may be used to repair unmarked direct-buried jacketed supply cables and communication cables.
