Aca

Doing my ACA on Monday.
Heard we should now be using rubber shielding and insulated crocodile clamps when doing a Ze.
How do you remove the earth cable and access the connections with this in place?
Can someone inform the procedure for this?

Cheers

remove earth cable from MET, AFTER ISOLATING THE INSTALLATION, then clip you croc on the earth cable.

 

[thomas-1981]

No the croc clips are to hold the rubber sheet in place. I know how to carry out the test. It's the Health & safety sequence I need to know in regards to this rubber sheet.
thanks

I can't fit the life of me think why you would need a rubber sheet to cover any exposed conductive parts?
the tester will not allow a voltage of greater than 50v anyway, and you will have already verified that these parts are in fact bonded (where required) before the live tests take place.
also, can you imagine the amount of rubber that would be required in say a factory?

i really don't see the point!

i sat my aca 2 weeks ago its a piece of pi%%

 

[thomas-1981]

I do agree, just something I'm sure I heard or read somewhere.

 

[Fast&Rough]

the rubber sheet is overkill incase the live pops out the main switch and makes the install live while the main earth is dissconected

 

[thomas-1981]

So is this sheet a requirement during an assessment?

 

[Fast&Rough]

yes, its complete overkill

 

[thomas-1981]

So how are the tests carried out with this in place over connections?
Thanks for your help

 

[Fast&Rough]

the sheet is clipped just below the connections so the probes are passing over the sheet ,the board you carry the test out on is about 5ft off the ground

Cheers mate

nb the questions at the end are the hardest part if you are finding them tricky work from the back of the question paper to the front and take a bottle of water with you it gets quite warm when some random guy is asking you a million questions while youre trying to test something

 

[telectrix]

sounds to me like another daft H&S lunacy.

 

[Knobhead]

If you need rubber sheets you're doctor can help.

 

[Silly Sausage]

I would've thought somewhere like Ann Summers would be more helpful.

 

[Knobhead]

Ann Summers? To expensive, try Ms Comfort @ Cocoon rubber. Much cheaper.

 

[Silly Sausage]

I won't ask on an open forum how you know that! :smilielol5:

 

[Knobhead]

I knew her parents who started the buiness.

Anything wrong with that?
