Re: Calculate the min size of cpc giving consideration to disconnection times and the
Couldn't you just find your maximum demand and look in the bgb for what size cable can carry this safely and then do your volt drop calc to check volt drop if it doesn't comply then go to next size cable and do the calc again and so on, as for the 50kA fault current a type b BS EN 60898 only has a breaking capacity of 6kA or 10kA so you would have to change this for your fault current size why not use a BS 88-2 fuse as these have a breaking capacity of 80kA then do the adiabatic to find your min cpc
