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

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

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