S = Solid C = Concentric Strand B = Bunched Strand RC = Rope Concentric Strand RB = Rope Bunched Strand

Bunched Strand: A collection of strands twisted together in the same direction without regard to the geometric arrangement.

Concentric Strand: A concentric stranded conductor consists of a central wire or core surrounded by one or more layers of helically laid wires.

RB=

Rope Bunched Strand: Rope strands are assemblies of bunch-stranded members.

RC=

Rope Concentric Strand: Conductors are available only in the specific numbers of wires necessary to make up the construction in concentric layers.These numbers are 7 and 19 conductor groups.

A single solid wire of the stated gauge size.
