Ex: 9/96/93 is for Component Color Code - (Required for cable constructions only)
Replace XX by number(s) indicating base color followed by stripe(s) as required. Slashes are used to separate individual component wire colors. Example above: 9/96/93 = Components are coded white, white with a blue stripe, and white with an orange stripe, with an overall white, crosslinked ETFE jacket.

Ex: 9 is for Base color of primary wire or cable jacket
Replace X by number indicating base color for primary wire or cable jacket (0 = Black, 1 = Brown, 2 = Red, 3 = Orange, 4 = Yellow, 5 = Green, 6 = Blue, 7 = Violet, 8 = Grey and 9 = White) Additional number(s) after base color indicates stripe(s) color(s); for example: 95= white wire with a green stripe; 952= white wire with a green stripe followed by a red stripe (see example below)
