Steps,
2391-10 is the "old" 2391 - Inspection & Test
2391-20 is the "old" 2400 - Design & Verification
Both are level 3 qualifications
You can't do 2400 unless you have done 2391, then you have to sit the 2391 prac exam as well as the "2400" theory & project.
So there are 4 parts to the 2391-10/20 qualification in total, the 2391 practical, the 2391 theory, the 2400 theory & the 2400 project.
The closed book 2391 is al bout I&T including periodics, the 2400 is about fundamental design, you know about the 2391 and the new 2391-10 is an identical syllabus and is a closed book written exam IIRC 3 hours?
The 2391 prac you know the board with single & 3ph circuits etc. to do a periodic on in a couple of hours there may have been fault finding too? I can't remember now!!!
The 2400 project is a totally documented fundamental design of an installation, more often than not from a spec and commercial.
You have to do all the cable calcs for the loads, draw up the layouts cable runs, decide on the wiring materials and containment with justifications, you have to select all the accessories, lighting etc and justify, you need to allow for any special loads etc. mine had a lift, so you need to then allow for the regs around lifts etc. you have to consider ring loads, volt drops in rings for fixed loads if you use rings, there is normally something in the spec to force you to use at least one ring!
The exam is then design calcs on cables, volt drops, Zs, ccc, etc. there will be some I&T in it also, it is again 3 hours with 10 questions all long answer, a regs book, gn3 & the osg available to you. Remember though you can't sit this according to C&G rules unless you have passed 2391.
I don't remember being allowed books in my exam though, I did mine before the Rev did his.
See what Canoeboy can remember from doing his, not sure when he sat it?

The "joking" 2931 is actually 2392.

Both of these qualifications along with several other related ones are showing last registrations as 31/12/11, so they look like they are all being terminated?
