bs7671 , guidance notes 3 amendmant 3 tables wrong?

[Mike Blair]

looking at zs readings for type b bs60898 circuit breakers in bs7671 "page58" and looking at page 121 in the guidance notes 3 and seeing different readings??

This is a well known error.
The revised tables, for both GN3 and the OSG are available as a one page download from the IET site.
The Table in BS7671 is correct.

Yes Mike they have really made a big c00ck up on the Zs table. There is a download from various web sites. They even handed out an A4 print out when you bought a new copy for the OSG/GN3 from the IET.... Whoops, a bit more proof reading would be good lol.


Edit:- Alan beat me to it.

So I'll be better off keeping my counterfeit amendment 1 GN3 as it has less serious errors in it ?

Seriously, if they are going to force us to fritter away our hard earned every couple of years or so, they could at least make the mugging feel like it had at least some value to it.
In other words they could at least sprinkle a bit of sugar on the turds they are serving up for dinner.

I'll download the errata and make do with that.

hahaha!!! sprinkle a bit of sugar on the turds best saying i have heard in awhile

There are a fair few errors in the other guidance notes as well, probably not as bad or comparatively risky as GN3, but still indicating pretty much no proof reading.
I am sure the outlay is worthwhile! might as well buy a comic, more fun, less errors.
