Further to the above, we will include the option to consider the magnetic effect of the SWA when a separate CPC is involved based on the PD CLC/TR 50480:2011 UK NA.
Also, we will include the other checks about the separate cpc withstand and also the SWA cpc withstand, based on the portion of the Ief in each case as mentioned in the UK NA.
I hope that helps and many thanks again for the feedback.
