Ib = 10000/230 = 43.5A In = 45a Type C BS60898 Circuit Breaker It = In/rating factors = 45/1.03 = 43.7A 6mm @ 47A Mv/A/m x Ib x metres / 1000 7.3 x 43.5 x 15 / 1000 = 4.76v This is what i got... Stu

Hi mate, only problem with your answer is finding the volt drop. mV/A/m x Ib x Metres 1000 so... 7.3 x 26 x 20 = 3.91v 1000 Hope this helps Stu
