December 1st 2391 exam

[brav]

Anyone here sitting this exam?
Im sitting it at Dudley college, bricking it but had to get to it sooner or later.
I was reading a city and guilds report on a past paper and it sounded as tho the pass mark depends on passing the top 40-50% nationally ? So i could get 90% of the answers correct but if nationally Im not in the top 40-50% i could still fail?
Also are u marked down for spelling errors, iv only done online exams so far and been sucessful, all distinctions for L2 2330, high 80's percentage for 2382 2392, 100% for PAT, but non were written. Are u allowed calculators or are u not allowed to take anything in with u?

Why is there 6 tests for ze on 3 phase?? I thought you test between L1-earth, then L2-earth, then L3-earth, and write down the highest reading?? Am i wrong, if so i cocked that one up as well.

I agree with you fredrico, thats how I constructed my answer too mate!! The most important part... of course being "reconnection of the earthing conductor" which has been beaten into everyone by now I think lol. I know several mft can record pfc simultaneously with ze at this stage?!! which would amount to 6 tests and possibly cause confusion.....but we were not asked to do this?!!

Yes sorry there are three tests.
Wot about the Supply Transformer to MET for tt, tns, tncs question? Did u start at Transformer i.e. transformer, supplies Line conductor.. etc, or start at MET i.e. MET, installations Earthing Conductor...?

I just said, TN-C-S, earth goes backe down the supply cable neutral, TN-S, earth goes down either the supply cable armour, or a seperate earth conductor, and TT the earth goes down the consumer earth spike and through the ground mass of the earth. It was not worth many marks so did not go into much detail.
