Test 1

My recollections were that I did better than expected. Strange as it may seem, I revised a little more than I otherwise would have done. Having to make reference from AS/NZS 3000 for C table was a good idea. More use of documentation helps you to navigate more freely when you know where to go for information.
Mind you, without 3000

3 Phase board

This was an interesting exercise as the following results will show.

Problems found:

conductor insulation visible, hot water element visible, a number of switches exposed, bad cable connections, switchboard too close to floor, the list goes on and on.

If I was responsible for an installation such as this then I should be placed against a wall and shot.

Obviously the idea is to prove our understanding of what is and is not acceptable from a safety point of view.

Certificate of Compliance

This certificate is "for a low voltage installation if prescribed electrical work has been done on any part of it and the prescribed electrical work involved placing, replacing, or repositioning conductors or fittings attached to conductors".

This document is very important as it stipulates the work that has been done by an authorized person and that that work conformes to a standard as laid down. Depending on the type of work done is dependant upon whether an electrical inspector is required to inspect and sign off the said work.

Test sheet

These test sheets are a record of the installation test measurements performed to ensure conformity with electrical safety. Nobody is in danger when using the system. Are they a legal requirement? Thinking about it, they probably are. They are a good thing to have. Plenty of practice would make me feel more at ease when filling these things in.

Conduit

Conduit pipework of the plastic kind wasn't difficult to use so long as you had your
installation drawing correct. This enabled cutting to length easy. Bending to shape was easy too and terminations into fitting were of a push fit type. You could possibly use cement to firmly secure the fittings if reqired.
An alternative to plastic is steel which could have been used. This requires pipe bending equipment and requires more accuracy when fabricating.

Cable joints

All 3 cable joints were staggered and then crimped to their corresponding colour coded ends. These crimped areas were also covered in heat shrink sleaving to ensure isolation from one another.

The armoured outer sheathing of the cable was also crimped.

The complete joined area was then covered in a hard protective shell and filled with resin. Curing time was around 2hours.

Testing of the cable joint was done using a megger @ 500v.

Light testing

The main check was to ensure that no transition had taken place and that the 2 way switching was working. A problem was discovered that a switch live was incorrectly placed. This was corrected and the test completed. A multimeter was used to diagnose the problem.
