T& e cpc

[EddieB]

Guys
with the older 2.5 T&E the cpc is smaller than 1.5 (1mm maybe) I know the calc with a 1.5 cpc is approx x 1.67 anybody out there know the calc for a 1mm cpc

Looking at the OSG, resistance per metre in milliohms is:

2.5mm2 = 7.41
1mm2 = 18.1

Therfore, as a multiplying factor it is 18.1/7.41 = 2.44


Cheers
Steve

r2 = r1 + r2 x csa line / csa cpc + csa line
