I am filling out test sheets and have a merlin gerin D32 C60 HD double.pole mcb. The rating on the mcb says 415V feeding 2 feeds to a canalis busbar.
BS7671 States max zs for D32 0.4 secs is 0.34. Is this just for single pole MCB?
I have also check my max zs value
from manufacture stating 0.51.
The reading I got at the furtheast light fitting at the tap off of Busbar was 0.47.
So question been do i go with bs7671 or manufacturing result??
