Each core is 35SQMM (Core Red , Yellow , Blue)

To measure the conductor SQMM as per below

From BS 6360 Show that : 7/2.52mm

7/2.52mm is per below ;
Single wire diameter : 2.52mm (Based on BS 6360)
Number of Strand : 7wires (Each wire is 2.52mm)

Calculation

=(2.52mm)(2.52mm) x PI()/4 x Number of Wire (7)

= 34.9131 approximate 35SQMM
