Did any of you sit it? I didn't think it was TOO bad, couple of questions I was a little unsure of but overall ok. How did you guys find it? I can never think of the bloddy questions afterwards!
 
The anxiety of the wait has hit me the first day after the exam, and still with me. The clock will tell but it's a case of have I got it or have not for the next month or two. We're all in it together fellas. Hope we get through and be back to tell our story. :)

Totally screwed up on that question then. It's so obvious when answers are in front of you, and you draw a complete blank at the time! I stated it would record an inaccurate reading for first answer, 2nd answer stated the entire length of the circuit will not be tested.....duurgh! live and learn I guess!

I know exactly what you mean!!

Q5)
State three inspection checks that may be carried out on an armoured cable installation using the sense of touch?

Any answers?

Q11)
State the effect on measured values of insulation resisLance of a230 V circuit if an​
insulation resistance test is carried out

i) between live conductors to earth with a tungsten lamp in circuit

ii)between live conductors with a switched fused connection unit, having a
neon indicator. left in the off position.

Any answers?




Is that exactly how the question was written in i?

'Between live conductors to earth' could mean between L+N joined together to earth in which case the lamp would have no effect.

Not that I'm in any way suggesting ambiguity in a City & Guilds question!

Perfect example of me not reading the question properly. Funny how sometimes your brain only sees what it wants to see.. Of course the lamp would have no effect when testing to earth.
RTFQ!!!!!

I agree that it means L+N - E , but even if it were just L-E, it wouldnt show a dead short . it would only do that if it were L-N.
