Who concocted this crap? It has nothing to do with any inspection and test procedure.

It has no relevance whatsoever to BS7671. The only option for CU's and switchgear, is that meets the required British Standard in the case of MCB's RCD's RCBO's etc it is BS60898, BS61009, BS61008 and so on, cant remember what BS no's apply to CU's there are a few. As long as the kit is compliant, price has no bearing on the issue whatsoever.

Tell whoever set this question, to do something more relevant to the subject, like asking things like "Where an RCD is used for additional protection on a new ring final circuit, it should operate in how many ms at how many times its trip current, and how many mA".

Cheers...........Howard

Are they asking, re-wirable fuses, cartridge fuses, MCBs, RCBOs. Split CUs, high integrity CUs, never understood why they are called high integrity though, with the pros and cons of each?

 

[SirKit Breaker]

They shouldnt be asking random stuff, City and Guilds wont!. Your course, exams, and practical assessments should only contain relevant info from GN3, GS38, OSG and BGB. Anything else is totally irrelevant to the qualification. GN3 contains all the relevant bits from the other books, so you only need to learn one publication, but need to be aware that it is connected to the others. If you know and understand GN3, you will have no problems.

Absolutely!
Best thing I find before an exam is to just chill out, forget about the subject and finally stroll in there like a calm thing on a calm day.


Oh yeah, hope it goes well for you!

meh , pass or fail , i know i've put the hours in so we'll see how it goes on the day , i am fairly pragmatic towards exams.

I smashed the exam main questions where draw a earth fault loop path on a tns system 15 marks, testing ring final conductors 15 marks and list 5 things to check on a socket 10 marks

 

[andyk1969]

just got back from sitting it myself, funny how the simple things just escape you on the night which five things did you list? we have been revising old 2391 papers and i found the questions tonight to be completely different in there wording which does throw you off very tight on time to

Might be in a converted viaduct arch.
I've taken engineering exams in a nightclub.

 

[mwigham85]

Polarity, earth sleeving, live conductors insulated, correct colours, connections mechanically sound but in gn3 it's different so maybe not as good as I thought. You?

Did you remember your zones?
