What does the 2.5 cm actually refer to? The diameter? And from time to time I come across lengths of cable disposed of in skips. I've got a good 6 metre length of cable that is twin and earth and looks as thick as that used on my cooker, and it says 2 x 10 + 4 on the side. It's 16 mm at its widest. What would this be? 3.5 means 3core and neutral is half.4core means all of 4 CORE R SAME SIZE.GENERALY WE CAN GET 4CORE UP 25SQMM CABLE,AFTER 25SQMM 3.5 CORE,NOW A DAYS 1,2,3,4,5,6,7,8.
