Wiring schematic question

[bread]

Can someone clue me in on the nomenclature contained in the wiring schematic in the owners manual of my B2150. What is the meaning of the captions next to the individual wires, for example, 0.85RW, 1.25RL, 2RW, and3R. I understand the letters define the color of the wire, but what do the numbers represent?
Thanks fr thee help.

0.85, is wire size in mm
RW Is Red with White stripe
RL is Red with Yellow stripe
3 is 3mm
