Has anyone noticed any differences between the New ON-SITE GUIDE and the Big Red 17th Edition regs book?.
I have noticed that some max permitted zs values are different.
For example
OSG says BS EN 60898 TYPE B 32A = 1.16 ohms
and
Main 17th Regs book says BS EN 60898 TYPE B 32A = 1.44 ohms

Is it just me reading it wrong?
if im correct, which one are you supposed to be following? as their both current 2008 17th.

Thanks in advance...
