Figure in Blue = Approx Total Internal Area of Trunking
Figure in Red = Approx Section Cable Area
Figure in Purple = Approx number of each size of TW/E cable for
the selected size of Pvc Trunking
Based of IEE regs " the number of cables installed should
be such that the resulting space factor does not exceed 45% "
