2391 March Completed

[vernam616]

Came out of the March 2012 exam liteally 30 minutes ago, anyone done it? How did you find it?

 

[i=p/u]

same as most id say, only chosen ones get to dance with mims

 

[Ben Grant]

forgot to mention to link out the contactor and time switch. duh, could be costly.

 

[i=p/u]

just hold contactor in

Only worth 1 point each but you'll only get the points for:
Cpc - a circuit within the installation An exposed conductive part

Main protective bond - extranious conductive part within the install i.e water or gas pipe

Earthing conductor - consumer unit the means of earthing

See Fig 2.1 in BS 7671

 

[vernam616]

I dont have bs7671, could you state what it says please?

Reading some of your answers is making me worried now haha, i also forgot to link out the contactor

 

[Ben Grant]

that may mean that you lose a mark or 2. the sequence is still correct if you did forget to mention. I hope as I also didnt state to link out. I really dont know how strict they are with the marking

I tested the lighting circuit in two parts. Up to contacted and the from bottom of contactor to lights. IMO you would be doing well to hold contactor in and take readings logistically.

You really would just link it out though

 

[timbobelfast]

With the time clock already linked out no issue in doing it in two parts.

link out the contactor than link the live to the outer sheath from 1 end than mesure from the other end of the cable between live and outer sheath

 

[Adam W]

Yeah I put link out contactor and time switch

I answered the same - disconnect contactor and time switch and link out.

Yeah it didn't state where the contactor and time switch were, while it said the DB was next to the supply intake.

I'm totally stoked I read this thread because all day long my colleagues and I have been debating over whether we did really well or absolutely ****ed it up and looking at all your posts I'm now certain that we definitely did one or the other, but we're not alone.

3 tests after earth electrode test on TT installation - If that is Ze completed, then I got told in practical to carry out PFC after reconnecting earthing conductor.....EAWR say only do live testing if absolutely necessary so Zs could be calculated....that leaves other physical tests as RCD (TT install.) and functional tests. So PFC - RCD - Functional...Maybe !
