One question I have is that for calculating full load current will the current be divided by k factor value or will it be multiplied by k factor value beacuse k factor is correction factor means it is derating the cable current depending on certain parameters so full load current should reduce and for that we should multiply the current by k factor. This is my assumption, please correct if I am wrong.

Some industry is maintaining a power factor of 0.95 and if we are to choose wire size then we take solar load into consideration. e.g. if we have a 50 kw solar project then Solar load will be at a max not more than 50kw and power factor will be maintained. So can we chose the wire size on that basis or we will have to consider PF as 0.8 for all cases. Plz clear.
