It should be noted that the colours indicated in the table are often combined in pairs e.g. 14GY-C.

The number '14' represents the cable size , the cable comprising of 14 strands of wire! each

strand being 0.010 in. diameter. The 'GY' indicates that the cable is two colour, Green and Yellow

and the 'C' ~ndicates that the cable is cotton covered.

CABLE COLOUR CODE CABLE SIZES CABLE TYPE B = Black S = Slate 14 = 14/.010in. 'C' denotes cotton G = Green U = Blue 28 = 28/.012in. covered cable N = Brown W =White 4 4 = 44/.012in. 'P' denotes plastic P = Purple Y = Yellow 65 = 65/.012in. covered cable

R = Red 120 = 120/.012in.
