The below is copy and pasted from somewhere else but a great post that explains alot
The test is over 3 days: mon-wed or tue-thur
8am start prompt, finish at 4ish.
theres four sections to complete, listed below:
Section A
Fabrication has been removed entirely as it is thought to be a level 2 skill There are also increased expectations on ability to think about installation design. For example, the correct choice of protective device, the selection of RCD/RCBO for relevant circuits and the correct overload setting within the DOL starter which will be changed frequently so has to be calculated on an individual basis.
Below are some of the expectations for the new qualification:
.SWA termination
.SY (Armourflex) termination
.Twin and CPC (2 way lighting circuit) Wiring in singles
.FP200
.Compartmental trunking
.Tray
.DOL starter and motor circuit (starter pre-wired)
.External socket (to be RCD protected)
.CO2 detector
.Thermostat
.S Plan heating system
.Solar panel
.Earthing systems
Section B and C
Inspection, test and fault finding. This time, the expectation is on the student to complete a full set of BS7671 paperwork, an EIC, Schedules of test results and inspections.
Section D
A 30 question multiple choice paper which will relate to the AM2, such as working safely, risk assessments and methodology. I think this is relatvely easy exam, no need to revise really, you should now them all, if you dont there is 4 books on your desk to look through.
Installation - 8.5hrs
inspection and testing - 3.5 hours
fault diagnosis - 2 hours
multichoice exam - 1 hour
The installation: 3-phase db in the middle wall, we have 3 walls to a bay.
.Safe isolation first thing you do, you must pass 100%
.SWA termination from the db, out at the bottom, glanded, onto cable tray in a 90degree bend into a 3phase isolator. singles into the commando socket from the isolator. 4 core, 6mm, 3 pole MCB, 123 brown black grey, 6mm earth to bond db.
.SY (Armourflex) termination - lightweight armour cable, out of the DOL starter (pre wired) down onto cable tray into a metal box, which is a pretend motor)
.Twin and CPC (2 way lighting circuit) Wiring in singles - In compartment trunking, feed the first switch, strappers, then the last switch, then upto the light.
.FP200 - out of the db, in compartment truking, into fused spur, out of stuffing gland, up the cable tray into the co detector connections.
.Compartmental trunking - all installed for you, lid is cut into little peices and numbered up once job is complete.
.Tray - installed for you, 2 lots
.DOL starter and motor circuit (starter pre-wired) singles 2.5mm into the starter, earth goes onto the casing, sy cable away to the motor box.
.External socket (to be RCD protected) spurred off the ring main, the socket above it. 3 sockets and a fused spur. make sure your fused spur you go in-and-out of the "supply" side. 32A RCBO
.CO2 detector - - out of the db, in compartment truking, into fused spur, out of stuffing gland, up the cable tray into the co detector connections. unswitched fused spur, p-clips up the tray, 6 or 16A mcb
.Thermostat - pre wired, just plugs in. Once you have wired your s plan heating system.
.S Plan heating system - takea around 2hours to wire, using singles and flec cables thats already installed at one end. basically you get a nice wiring diagram, cant go wrong, its like dot to dot. Looks real hard but once you get into it, double check the numbers beofre you connect each end up.
.Solar panel - same as above, its fed off the heating system
.Earthing systems - 10mm gas and water from db, down tray to gas and water pipe, seletcr the two clamps provided, gas - before the branch. water - after the tap (bond)
Earth everything metal
.Data - first time i did, easy, remember to use bridge inside trunking, for segraration.
.Ring main - wired in singles, left hand side wall, 3 sockets, 1 spur 1 outdoor socket spurred off.
Inspection and testing
Inspection - take all covers off your job, do a visual on connections etc
. continutiy r1r2 method - all circuits
. gas and water, r2 method <0.05 max
ring main - end to ends, fig 8 crossover
.Insulation resistance
-spur off, co2 off, disconnect life from light, rcbo off and fly leads out
no actual motor there, but say you would disconnect if there was one there. 500V 1Mohm pass.
- main switch off, mcb on, isolator on (3phase skt), turn on everything. Global IR test accross everything (l1 to l2, l1 to l3 etc...). then go back and test load cable on contactor (sy), ring main 1 leg, two way switching.
.Polarity
-confirm polairty, incoming terminals, covers in place then power up, make sure mcbs and main switch is OFF.
.Ze - you can ask for this (enquiry) examiner will give you it, saves you tesing it. be aware as he may give you a high one, to see if you realise its too high for the system type, or when you add your r1+r2 togthr with it later, 1 ciricuit is generally too high - which you MUST note in the test sheets to pass.
.Zs - now add up your results like ive just mentioned, on site guide 2d pg 103. rcbo - generally too high.
pscc - you do this test, with him at hand.
.Phase rotation - just a simple plug in, on the motor and 3 phase socket (*** ARROW TO THE RIGHT = CORRECT) - if not swap to phases over with anytime remaining and retest.
.RCD test, 3 test, 1/2, x 1 x 5, then a functional test
Fault Finding
Quite tricky - 7 faults. I think you need 4 or 5 for a pass.
Always 2 faults on the heating, 1 on the bonding conductor, 1 on the ring main, last 3 random.
- short circuit, open cirucit, cross polarity. but you may have a high resistance on the bonding conductor.
Online Exam
nothing to worry about to be honest, especially if youve just finished college. you get the onsite guide, the regs, building regs, and inspection and testing book. to be honest you should only need the book a few times. 30 questions, 21 marks needed to pass.
health and safety questions, a few on system types and testing etc...
once you have finished you should recieve your results within a few days, via email.
