first day done of my AM2 exam. Just wanted to let people know what I done and if I will loose any marks.
So first of all risk assessment and safe isolation. I completed the risk assessment no problem at all and the safe isolation I completed fine as well asked for permission to isolate, prove, test, prove, lock off and warning notices, key in pocket etc.
Install section:-
Lighting cicuit took 1.5mm twin and earth L and Neutral and cpc to my first switch, fed the common with my L and Neutral in the back switch. I then took a 3 core 1.5 to the second swith which was grey as my neutral which went into the back of the wago, brown as my S/L with brown tape and the other brown as my other S/L. To the intermideate I then took the 3 core and looped the Grey in the back as a Neutral again, then took my brown and black to the top or the intermediate. Again, sleeved correctly. Another 3 core out to my last switch done the same again brown/ black S/L and neutral into another wago. Then, 1.5 up to the light as my neutral in the wago and the brown into th common. All cpc linked in wago is back of switch as well. MCB 6 Amp Type B
Ring Main
2.5mm and 1.5mm cpc from db to first socket, though to the spur, and to the last socket, last socket then back to the db. Then took 2.5 and 1.5 to the outdoor socket on the load side of the Switched spur. Ring on a 32 amp RCBO type B.
Bonding
10mm for water and seperate for gas.
Gas to first part of the pipe before the T joint.
Water connection just after the stopcock/ first section of pipe. Back to the db seperate and labeled.
Fb 200
Supply from DB to non switched spur. From
Non switched spur up to co2 alarm. A seperate length of FB 200 On cable tray using P clips and bolted to the tray. tighting of glands etc also on a Mcb 6 amp type B.
3 phase and neutral isolator. 4 core 2.5mm from db to isolator, again banjo and glanded at both ends. Used 1.5mm cpc as bonding cable inside db for the banjo. Then 2.5mm 3 phase colours and 1.5mm cpc to commando socket. Then looped neutral in back of isolator using a wago. 3 phase and earth connections.
3 phase dol starter
3 phase, neutral and cpc to dol starter.
Sy 3 core and earth to motor box. Glanded off and cable tied to cable tray. Marked 1 as L1 , 2 as the Black phase and 3 as the Grey phase.
S heating plan ill do tommorow along with thermal overload to work out of the motor and the data points. I still have 3 hours left.
Does all sound good? Or any hints or tips on things ive missed out?
Inspection and testing tommorow and fault finding
Cheers!
