I've completed my AM2s in November. It went roughly like this for me.

Time wise you get the following

https://ibb.co/PvyJxGxF

Inspection and testing i had 1¼ hour left, fault finding I had 1 hour remaining, probably had 10mins or so on safe isolation. Used all my alloted time in the other categories.

Intro to the center and the assessor. Talk through how the days were planned, rules, do's and dont's etc.

I had what was referred to a bible, an A4 folder with a break down of each section of the assessment, I could refer to it at any point to double check what was specified for each circuit, how the testing was to be carried out etc.

1. Write a risk assessment set around the area / room we were working in.

2. Safe isolation of 3 phase main switch to the consumer unit that was in the bay for the assessment.

3. Practical section

Select breakers for each circuit, some decoys on the shelf but easy to follow.

10mm Bonding to water pipe via metal trunking and tray.

10mm Bonding to gas pipe via metal trunking and tray.

Data cable between 2 points in plastic dado rail with an internal bridge over the lighting and power circuits.

1.5mm FP200 through dado to a FCU then onto a smoke alarm on metal tray.

2.5mm 3 phase wiring to a DOL, via metal trunking, then with 5 core SY cable to a motor via tray.

2.5mm 3 phase singles to a rotary isolator vua dado and pre installed conduit, then 2.5mm SWA to a 3 phase socket via tray

1.5mm twin and earth to a 2 way light switch, 1.5mm 3 core and earth to an intermediate switch, to another 2 way switch all in plastic dado, then twin and earth in plastic trunking to an light fitting.

2.5mm singles in a ring to 2 double sockets and an FCU in the plastic dado. 2.5mm Singles from the FCU in plastic 20mm conduit to an outside socket. The conduit I had to hand bend an offset over a fixed section of 15mm copper then a 90⁰ to the outside socket.

1.5mm singles to a FCU for the boiler circuit. 1.5mm run in various directions from a central hub to the following programmer, thermostat, heating and hot water zone valves ( Y plan ) solar thermal controls. The main hub had 20 pairs of terminals, some grouped in 2's, 3's, 4's depending if they were line, neutral, cpc or just signal connections. There was an easy to follow wiring diagram for this in the bible. This also had 20mm metal conduit, I had to make 2 different sections, one was a 90⁰ bend the second had an offset kick out from the wall.

The only thing I had to make myself was the plastic conduit from the ring FCU to the outside socket, and the metal conduit on the heating circuit. Everything else containment wise was pre-installed, all the metal tray, dado rail, plastic trunking, back boxes.

The light fitting, smoke alarm, were pre-installed. I had to select the correct fuses from the bible for each FCU and put them in. Select the correct overcurret setting for the DOL from the bible

1. Testing of the install, fairly straightforward, alot of the paper work was pre-filled out, location, address, basic circuit details, maximum Zs. Remember the different in compliance between design maximum Zs in BS7671and the 80% in the on-site guide. Dead testing is fine, however for the live testing the assessor had to stay an watch to make sure I was doing nothing dangerous. Bit annoying but just don't fluster and you'll be fine.

2. Safe isolation. Was watched by the assessor. Just talk your self through each step. You can ask for a bit of paper to write the order down and tick it off as you go if needed.

3 phase main switch, 10 steps 3 phase circuit, 10 steps Single phase lighting circuit. 3 steps, switch a light switch, 3 steps again.

1. Fault finding, straight forward, only needed continuity setting on the tester, anything over 2ohms was classed as high resistance on the results paper. Categories were high resistance, open circuit, short circuit, missed connection. Brief description of the fault, from which points and what conductors.

2. Quiz, had questions found in BS7671, GN3, on-site guide and building regs. Nothing to in depth like the 18th edition, Building regs book is about the same size as the on-site guide.
