12 way 3-phase dist-board. Circuit 1 spare circiut 2 Co2   circuit 3 lighting circuit 4,5,6, 16amp cammando socket circuit 7 ring circuit circuit 8 heating circuit 9 spare circuit 10,11,12 dol starter. Calculate motor overload= convert W to kw/by 3 then by 230 multiply answer by 110%...

It could if section A, termination of the 4core swa, or earth attachment from the banjo within the dist-board or earth attachment within the 25amp isolator. Wrong size cable from the 25amp isolator to the 16amp 5pin socket [line and cpc sizes].  The AM2 assessor should have given you feedback...

Lighting circuit is wired as follows: feed to switch 5 [6242y],[ feed to light from switch 5 6242y], then 3core and earth [6243y] between switches 6 and 7. CPC terminations and any others within switch back boxes must be completed with screwless connectors.Donot forget table 51 eg colours for...

The self assessment check list is mandatory from April this year and has to be signed by the candidate and/or the employer or training provider.

Live testing: Test mains polarity and phase sequence. Test Ze: remove main earth test between L1 N +E, L2 N+E, L3 N +E record highest value as Ze. Re connect main earth and test for PEFC and note the three readings then test for PSCC and note three readings. take the highest reading and double...

Lighting circuit: Twin and earth [6242y] from DB to first two-way switch. Twin and earth [6242y] from first two-way switch to light. Interlink first two-way switch to intermediate switch with three-core and earth [6243y] and also between the intermediate switch and the last two-way switch...

The Four wiring faults are: 1. Short cct 2. Open cct 3. Cross connection 4. High resistance

Section C has changed: now 2.5hrs more items to safely isolate.

Zs for motor cct see page 76 GN3.

Candidates for the new am2, beware of this information as some of it is incorrect.

The new am2 has four assessments[sections] A,B,C & D. Assessment A is further split into two sections A1 includes Risk Assessment and Safe Isolation of the rig assigned to you, time allowed 1 hour. Section A is your composite installation, time allowed 8.5hrs. Section B is, Inspection...

What happens to the conformity certificate?

Faults are: open cct, shortc cct, cross connection and high resistance. Use the meter on the ohm's setting not on the buzz. 1. usually feed to green button swtich. 2. keep meter on ohms should read 2.5 ohms for high resistance. 4. faulty valve yes you right no equipment faults only wiring...

Fault one: open cct feed to start switch inside DOL. Fault two: open cct or high resistance in bonding. Fault three: L/E fault on feed to circulator [pump]. Fault four: Motorized valve micro switch faulty.
