TT Max ZS loop reading for circuits over 32A

Iam purposely avoiding looking at the BGB (although I have it), because Iam still trying to get on a 2391-10 course in around September, and don't want to end up mixing the regs between the BRB, unless anyone can advise differently.

How I wish I did this when I was younger, instead of contracting for short term gain.:33:

I haven't got the BGB in front of me but I'm pretty sure I eye-balled the 25v a.c. touch voltage in section 710 (medical locations) in groups 1 & 2
 
HI all anyone know the above, i put 1667 ohms in the box normally for all TT circuits but noticed the other day it is only for circuits upto 32A

Anyone enlighten me, i need it for a 50A and 40A circuit??

thanks
In the BGB, the words 'for final circuits not exceeding 32A' have been removed from the heading of Table 41.5.
They've also removed the other voltages from the table, leaving just 230V.
