Correction for operating temperature

Is the correction factor for thermal insulation deliberately omitted? Page 429 BS7671

    Actually, having stuck it on a spread sheet, I think it is because Ci is generally punitive (low values). With low values of correction factors there would be no advantage in using the value of Ct derived from the formula to re-assess voltage drop. The real advantage is when there are no correction factors and there is a significant difference between Ib and It.
