It's a good check thoughTakes seconds to look at the Tables.
You’ve forgotten cmin so it’s 1.37ohms for 32 amp type B and not 1.44Zs < V/ 5In for B type. e.g.for a 32A . Zs < 230/(5 x32) i.e. 230/160 = 1.4375. ( then apply correction factors).
Zs < V/10In for C type.
Zs < V/20In for D type.
Thought you meant the 0.8not forgot. stated in post to apply correction factors.
