For any UKC / Passport holder, IELTS is only necessary if you need the points. There are two types of test - Academic or General. DIBP don't mind which you do, and as it isn't necessary for skills assessment, you get to choose. This isn't really relevant to skills assessments for Electricians.

As for the practical - there is lots of information in the forum on what you can expect - if you can't see any obvious threads, there is a search function in the tool bar above :)

That would be great if you could let me know what it is all about I have read up on a lot and the DOL stuff is no problem as I work on the industrial side of things anyway.

Still getting used to this site were things are

Were are you doing the skills test

Cheers

Cheers this would be a big help if you could let me know all about the test theory and practical i work on the industrial side of things so the DOL bits are ok with me it is the australian safe isolation it's a bit different to ours

Re: practical exam theory
 

Did you get sent a copy of safe disconnect / reconnect with the skills assessment paperwork?

Re: practical exam theory
 

I have not received my paperwork through yet so just gathering info at the moment

cheers

Re: practical exam theory
 

I'm sure I got sent one - or printed it out from Vic Uni website, but have looked and can't find it. I always worked with SILT = Stop, Isolate, Lock Off, Test - but I'm sure there was more to it than that. If I find it, I'll post it. The rest of what was covered in my test I've posted already, but I did do Vic Uni practical and not Vetassess. We had multi choice theory covering AC and DC, pf correction, leading / lagging, RLC circuits. DC resistor circuits - series and parallel. We also had to do a practical on the resistor circuits wiring up a circuit and calculating voltage, current or resistance at given points, then set up a variable supply to the correct output and connect meters to prove calculations. There was identify parts of a transformer and test. The DOL, wire and test. Disconnection / reconnection. Last was the domestic board, correct selection of cables and breakers, wire power and lighting to given drawing and test.

Hope that helps :)

Hello

Please, does Anybody know the maximum value allowable for the earth continuity resistance of an appliance frame to its earth facility in ohms

I have also researched and found Minimal insulation value to be 0.5M ohms

I think the answers are
0.05 ohms
and 0.5M ohms
is this correct ?
exam this Saturday

Thanks Dune .

Re: practical exam theory
 

Earth continuity resistance should be low enough to allow sufficient current to flow causing protective devices to operate in the specified time

Insulation resistance is 0.5Meg in UK and 1 Meg in Australia I think

Re: practical exam theory
 

Hello

Thanks .I was sure about minimal insulation value
the photo I took further up this thread was of actual paper I did about a month ago .
they asked the question and wanted a figure .what I thought they wanted was ZS ? This is obviously relevant to the CB protecting the circuit .
but If I remember the circuit was a 16 Amp 60898 B type protecting the circuit being used ???
Thanks Dune .

Re: practical exam theory
 

From a look up table in the regs, Re for a 16A type B gives a value of 1.15 ohms but I had to get a book out and look it up. As you are not gonna have a regs book in there - are you sure it wants an actual figure?

Edit - sorry - just re-read your original question, Resistance of appliance frame to it's own earth point so is only a part of Re - and I can't find a set figure even with the regs book infront of me. Have you got a copy of UK regs?

Re: practical exam theory
 

Hello
Yes I hope you can read this photo of the exam paper
Dune.

Re: practical exam theory
 

If its from frame to earth on dis board that would be Re. From frame to appliance earth stud then I think it's 0.5 ohms but I can't find it in the Australian regs at the moment :(

Re: practical exam theory
 

Thank You for your help
Dune .

Re: practical exam theory
 

Hello again

It is from earth terminal of tubular heater to frame of equipment / tubular heater

Re: practical exam theory
 

I'd go with 0.5 ohms then :)
