Hi mate, great work. I teach this as well, it is always good to see how others test etc. In this case very similar to me. I do question one minor thing, and I have had this conversation with colleagues as well. I don't believe that you can use the meters mechanical Zero Adjust screw, to adjust the zero reading on the M Ohms scale. The screw is only a mechanical resting point. I had a look through the manual and it does not mention this as an adjustment. I believe the M Ohms zero adjust is only adjustable internally.
Nice job , but I believe we're not allowed to use the load neutral of an rcd for multiple circuit connections , we must use a separate neutral link fed from the rcd, your video showed the 2 circuits on the right of SB had there neutrals terminated in the rcd load neutral . Cheers
Yes, I was going to so the same thing. One hole for each circuit neutral. Reason is, the two circuits may be fed from two different phases, say A and C phase, if the two twisted neutrals become disconnected from the link, the two circuits are now connected in series across a nominal 400V. This will lead to unequal voltages on the circuit loads. Perhaps, 100V on a washing machine and 300V on a TV.
5.4.3 Note (e) soldered Main Earth okay however 3.7.2.11 earthing conductors if soldered shall be retained in a position by acceptable means independent of solder.
When doing question 2.4 resistance of protective earthing conductors. What calculation do we have to show? During my LEP exam I did the same thing you did and what my teacher taught me, yet epic Itb marked me with a ZERO and said that I showed no calculation?! 🤔
If you test them separately and there happens to be a connection between neutral and earth, that you have not found yet, the test 500V will be applied across A and Neutral as well, which may damage electronics.
6:48 he said does it matter if you go between active and neutral but his hands are on earth to neutral, i assume it would matter if you are putting 500vdc across the protective devices, he must have meant does it matter to test between earth to neutral?
Nope he meant Active and Neutral, as he has a loop between the active AND the neutral so it doesn't matter whether you test to earth from Active or neutral
Step 1: pretend you've disconnected all electronic equipment Step 2: wonder why no one ever gave you the skills to work in the real world Step 3: wonder what "do the best you can" actually translates to in the real world.
Hi Talvin. Ive re uploaded the SWP vid. The exam has changed slightly since I made the SWP video, so keep in mind that its close, but would no longer be full marks. Ill make a new one sometime......
Matt K Thanks heaps for reuploading it, I had downloaded it with youtube red function thought that I can watch anytime later but apparently when you removed it now in my youtube offline library I cant watch it anymore. My SWP due this Saturday (19/11), hopefully you can make it available once again. Your videos instruction is simply the best, much appreciated. Thanks again for sharing your knowledge.
Dont you ever do an Earth loop impedance live test such as the ZS test? Also an external earth loop impedance ZE test live test? That tests the impedance from the mains active cable to earth at supply transformer, so that it proves the external supply is good, also an PFC test? In UK we have to do these live tests with an expensive calibrated tester plus an 5xs RCD tripping times test to fill out the test certificates.
What a legendary trade school teacher!
Teaches so concisely and straightforward
Your teaching is amazing thank you sir I learn a lot now ❤
Been 8 years since I did the capstone and worked the trade. Good reminder thanks mate!
Keep the vids coming mate,awesome stuff well delivered!!!
nice one dobbo
It would be great if you can do a update version of this Lep
Awesome educational video, good approach on explaining in detail.

Good job Dobbo and Teach, very informative and thorough vid thx.
It's official, Mitch Turner ...APPRENTICE OF THE CENTURY...............HAZAAR!!!

Thank you very much i hope u keep on uploading its a good review material
"C'MON TAYLOR THIS IS IMPORTANT!"
I believe this is also called the capstone test, atleast in WA, so good having these vids available as we can just watch and learn
Gday Nick is i possible for you to upload an LET and SWP Practice?
Thanks Matt K. Your video is very clear and helpful.
5.4.3 Note (e) soldered Main Earth okay however 3.7.2.11 earthing conductors if soldered shall be retained in a position by acceptable means independent of solder.
Yes but it cannot be under a screw if it’s soldered.
When doing question 2.4 resistance of protective earthing conductors. What calculation do we have to show? During my LEP exam I did the same thing you did and what my teacher taught me, yet epic Itb marked me with a ZERO and said that I showed no calculation?! 🤔
I wonder if Dobbo passed his test...
Do you have to join active and neautral when doing the sub circuits ? Or can you do them separately, like active to earth and then neautral to earth ?
If you test them separately and there happens to be a connection between neutral and earth, that you have not found yet, the test 500V will be applied across A and Neutral as well, which may damage electronics.
Dobbo got a small knobbo!!

"THIS IS IMPORTANT MITCH!"
Cheers for this vid legend
Are you testing on 500v through your RCD's and appliances?
250V for electronic devices, 500V for single phase and 1000V for 3 phase.
@@POPPIELOK 500v for three phase as well. The test voltage has to be double the voltage from line to earth
Video repeats itself with the same message?!?
Hi Matt, saw your SWP video a while ago but couldn't find it anymore. Could you please reupload it? Thanks heapsss.

RCDs will trip using megger
😅 good 👍

Yes, we have to do that in New Zealand as well
Love it
