Marina = special location!

 

[jimmy_one_ball]

Oh well, nice to hear other peoples comments. Whens the re-sit?

Completely buggered up the q.26 i worked out the safe touch voltage came out with 500ma like others, left and realised like many it was a special location on additional protection so 30ma :-(

Not Sockets
So you are correct about 500mA

Did anyone accidentally get the exam paper?

 

[jimmy_one_ball]

Our tutor dissapeared for a bit, think he might have photocopied it

 

[russty]

What did you guys put for the three practical considerations before a periodic? ... And where the hell was the 1 over rt banker question!

Myself,

Put down disruption to the office area so work to be carried out of hours.
Disruption to the shop which could cause loss of trade so work carried out of hours again.
Inconvience working in the toilet/shower blocks so only carrying work out on one block at a time.

I can't remember what Q26 asked now, I definately put 30mA because it was for additional protection. Then the test procedure was quite a few marks so must have included 5 X IAn as someone said earlier then the last part of the Q quoted the max disconnection time of a TT as 0.2s so I said the BSEN should be replaced with a BS to match the 200ms max permitted disconnection time. Well you don't have to get them all right do you lol

Also done thE exam tonight. Typical c&g... Found it hard to understand but we'll find out at the end of April how we done. Think I either scraped through or failed! Roll on June!!!

 

[jimmy_one_ball]

If I pass it will be a scrape, I gave some really crappy answers

 

[IQ Electrical]

Just for reference on TT disconnection times achieved with RCD's check out table 41.1 Note 2.

 

[lynj]

on section b

did they directly say the main switch was a 200 ohm rcd? if not thats why I went down the earth electrode resistance test route :X

 

[Liamsparks]

Nope but they did ask for the direct measurement of Ra which is then done like you would your normal Ze.

Thought that the wording of questions throughout was atrocious. Re the SWA cable - don't remember them asking only to test the cable, although the wording was crap, but they did ask for details of circuit preparation which I took to mean that they wanted the whole thing tested. For a 2 1/2 hr written exam you don't really need confusing questions.

ahh the good old city and guilds way of having you wonder what the question actually is. had plenty of them over the years. ambiguous sods they are

Well I felt terrible about this exam till I read half these posts, seems everyone found it confusing! Can anyone remember what they put for 21a? I think it was asking what documentation would be provided and what it would be provided for. I took this to mean electrical installation certificate for new circuit, periodic inspection report for installation testing, am I on the wrong lines cos I did have to read it a few times!
