Installation Rules-past papers.

[Blou Bul]

Sorry for the guys that are trying to make money off some ppl here. I am willing to exchange. I have complied a document with all the questions and answers. I used all exam papers from 2007 to 2011. If you need it just let me know. All that I would like is to get my hands on the 2012 to 2013 papers. Please guys ... let assist each other

Hi there,
I need info if possible please
I am a qualified electrician since '96 in Namibia
I want to do my wireman's license and applied at South West Gauteng College for a course called installation rules.
I recently wrote and passed both papers 1 and 2.
My question is what else is required to get my wireman's ?


Thanks Kyle

Good day guys I have also registered for Installation rules paper 1 and I will be writing in November. Could anyone help me with a study mate and previous question papers and answers for paper 1 please!!!.

The ECA in durban offers classes on weekends for 2 semesters and runs through the syllabus based on demand. The person doing this is Brian. He also does it with Skype for those who is to far to attend it on weekends. It's money well spend!

please help out with question papers and memos, if u the syllabus for both papers please help out. my email address is hlokselsithole@yahoo.com

im writing my first paper tomorrow, been given some predicted papers, but not all the memos were there and i found this thread here, thanks so much for the help, i downloaded the papers from your dropbox and got exactly what i needed, much appreciation from me, still very nervous for the exam, there is a lot of work that needs to be known, but good luck to anyone else who is writing tomorrow and next week tuesday the 19th, study hard and do well,

Hi guys can anyone help me with this question ?

Calculate the area of two core PVC copper cable of a DC supply
100 cell battery with full capacity of 250A/hour
Total internal resistance per cell 0.011 ohm
Total of battery pole connectors 1 ohm
Pscc = 92.522A
Length of conductor 100M

How did your exam go?

Hi guys can anyone help me with this question ?

Calculate the area of two core PVC copper cable of a DC supply
100 cell battery with full capacity of 250A/hour
Total internal resistance per cell 0.011 ohm
Total of battery pole connectors 1 ohm
Pscc = 92.522A
Length of conductor 100M

Let me take a go at this....feel free to correct me anyone...

PSCC = Eb / Rbbr , where Eb is the open circuit voltage of the batteries, and Rbbr is the total resistance of the network in ohms incl. internal resistance of battery and resistance of conductors.

So...

Lets calculate Eb first of all ;

Eb = 1.05 x Number of cells x 2V (page 272 in your Sans 10142)
= 1.05 x 100 x 2
= 210V

Next lets try to calculate Rbbr ;

Rbbr = (0,9 x Resistance of the battery) + Resistance of the battery connections + Resistance of the conductors (page 272/3 Sans 10142)
= (0,9 x 0,011 x 100 (there's 100 cells in this battery) ) + 1 + 2(x/1000 x 100m) - this is because there are 2 conductors and you need to find the Resistance value using Table E1 the 3rd column for DC circuits on page 307 of Sans 10142
= 1,99 + 1 + 2(x/10) simplify the equation in brackets - 1000 / 100 = 10
= 2,99 + 2(x/10) -- NOTE : we cannot find the resistance using table E1 as yet, as we do not know the size of the conductors -- this is what we are asked to calculate in the question

Using the information we now have, we substitute it into the original equation and solve....

PSCC = Eb / Rbbr
therefore,
95,522 = 210 / (1,99 + 2(x/10))
therfore,
1,99 + 2(x/10) = 210 / 95,522
1,99 + 2(x/10) = 2,198
2(x/10) = 2,198 - 1,99
2(x/10) = 0,208
x/10 = 0,208 / 2
x/10 = 0,104
x = 1,04 ohms

Now, using Table E1 on page 307 of Sans 10142, we look up the value of 1,04 ohms in the copper conductor column, which falls between 16mm and 25mm conductor size,
therefore,
we should choose the 25mm cable to be safe.

I hope this answers your question.

Regards

Simon

Thanks to DaveA for doing the deed.

My only desire for doing this, is to empower competent electricians.
Guys, take your trade very seriously.
It is regulated by law.
Take the time to study the regulations.
Write the exams.
It's over to you.

Hi Can please let me know who assit me with Master Installation rules Regulations and standards.
