I know I've got everything just don't want to walk in with everything then find out I don't need it or can't take it in if you know what I mean

From memory, BS7671, OSG, and GN3.

Good luck with it.

Yep,

There’s no time to read them, but you can take them in.

So you had to remember every max Zs for every type and rating of every protective device?

I never remember having to do that, we were always allowed to look those values up (the current values being in BS7671 OSG & GN3)

I think (memory is a bit hazy, was a long time ago!)....... when I sat 2391-10 if the question needed knowledge of a specific value then it was quoted in the question, as in something like "A radial circuit of yy cross section and zz length, is connected to an MCB with a maximum Zs of xx is it likely to meet disconnection times?"

That’s a fair one mate. But he was asking about taking them into the practical as you need to reference them when filling out schedule of test results.

Also times move on, they give you less information on the question and expect you to be able to find the answers in the book.

At the end of the day, we can’t be expected to know everything, but we should be expected to know where to find the information we need.
