1. what is Ohms law? V=IxR
2. use ohms law to work out a current value (V=240 R=40)
3. power question, voltage=240 power=2400W what is the current draw?
4. what are the components in a florescent fitting?
5. what is the capacitor for in the florescent fitting?
6. name two types of over current protection devices?
7. explain how to wire a two way switch?
8. name the components in a switch board (fuse board)?
9. what colours are the active, neutral and earth in domestic house?

11. what is the current rating of 2.5mm?
12. what is the current rating of 1.00mm?
13. can you use a different size cable to complete a circuit if you run out what you are using?
14. in a screw in lamp holder which is the active?

22. what test must you do before powering up a circuit that you have been working on?
23. what test instrument do you use to do an insulation resistance test?
24. what resistance readings should you expect/get when carrying out a continuity test?
25. how does an rcd (safety switch work)?
26. what can make the the overloads operate when a star delta three phase motor starts?

thats about as many as i can remember for now, if i think of any more i will post them.
if you do get the call from the TRA dont panic they arent that bad and will try to guid you to the right answer if you need it. it toke me about twenty minutes to do, but does depend each person and can take 45.

hope thats of some help to some one.

Cheers for that, it's similar to the stuff a fella on another forum had to answer. It may be my imagination, but they seem to be pinging a few people for these phone tests.
When did you apply for your ARTC by the way??Mine went in on the 2nd May, so hopefully be hearing something soon.

I was thinking of asking that myself, Si just read it and was thrown with a couple of questions though... What colour is the domestic active neutral and earth... is the same as UK? he's stuck on Q.16-18 though he's not a maintainence sparkie and can only just remember a class covering it in college... Is it important he knows all the answers Steve?

Anyone know if the new regs are out yet as peer still not got back to me.. need to send off for them ASAP we go soon..

Great post!,
Can anyone help me with the questions 19,20,21,22,23 and 26,
cause I'm not sure of the regulations/standards in Australia
and I will be having a phone interview this Friday 26/11/2007 ...
And what other questions are they going to be asking me

thanks in advance

ozoz

Same as england, If you have served your time you should be abale to answer those questions straight away

What type of switch is a start button ???? you are joking are you not

paul_ben

Sorry, but I'm not from England, and I thought that
I could get some help out from this forum, that's why I'm asking about the
regulations and the differences on those questions.

ozoz

I dont mean to sound rude - but if you dont know what type of switch a start button is you are not an electrician (its usually normally open/but can be normally closed depending on the machine - equipment).
