How did people find it?

Im 50-50

 

[CRAGS]

I did not find it to bad think made mess of last question... But maybe get some marks for working out etc made mess of direct measurement of earth fault impedance on lighting circuit read question wrong and did external fault impedance had like 10 minutes try and rewrite it my fault for rushing and reading question wrong

 

[CRAGS]

Already booked in for dec exam just incase

 

[brucelee]

good luck to you guys I am sure you will have done it this time crags what other things came up mate. I have still not had my cert from june exam lol had written confirmation but no cert college said it can take up to 8 weeks after getting results they must all be hand written

 

[SimpleSimon]

whats the pass mark?

 

[Phil]

good luck lads although i am sure you won`t need it don`t forget to post when you have passed when the results come in
60% i believe for the pass mark

 

[CRAGS]

Aup Bruce ring final circuit test again volt drop calc earth fault path etc. Feel I did better than last time I took it but weather I did enough time will tell.

 

[Markspark81]

Yeah i didnt really look at volt drop as i didnt think it would come up. thats a wasted 15 points.
glad the earth fault path diagram came up.
Im sure you have all done ok.

 

[CRAGS]

I put all calculations etc for drop but I am sure my answer was wrong. I was ready for earth fault path and ring circuit so hopefully picked up good marks for them. The zs test caught me out Not really a great deal to explain for 15 marks. I just dwelled on warning signs barriers etc removing enclosure doing test replacing enclosure obviously I went into more detail than that though..

 

[Jurasic Spark]

What was the part B scenario?

 

[CRAGS]

From what I can remember windscreen premises residents rewired for logistics and first floor offices. Steel conduit and trunking and PVC dado.

 

[Noom]

Do you know if you have to pass both A and B setions,or is it an overall mark

 

[CRAGS]

Overal mark most marks on sec b

 

[SimpleSimon]

I didn't think the scenario was too bad. Volt drop was ok.
The one question that stumped me was IP rating of the front face of a consumer unit. And the cover inside protecting busbar.

 

[Markspark81]

Knew they was gonna ask about the ip ratings 1p4x etc.
Did everyone get the exposed conductive parts? mucked that right up i think?
