Poor

excellent summary - thank you

Thankyou. A simple exam made hard. Good advice

U never made sure the circuits were isolated and checked they were dead

Could you do live tests never heard of “CRIPPER” but best video I’ve seen for my am2 not complicated just straight to the point cheers

Are these suitable for domestic installations ? I keep having nuisance tripping and have had several people come test sockets/appliances with nothing found each time.

So many oversights on this video. 1 - No Lock off , 2 No supply voltage check with test lamps confirmed working with proving unit. 3 You disconnect main protective conductors to copper pipe work so has not to pick up false readings on R1 + R2 tests via parellel paths. 4 To get a correct R1 + R2 result on the ring main you divide the reading by 4. 5 When doing an R1+R2 test on lighting take a reading from all fittings + switches and record the highest !

For the first test (continuity of cps) do you place ALL cpc's in the connector block? including ring etc?

Helpful, could you still complete the pper ?

Knock off, lock off, key in pocket, warning sign, prove, test, prove👍

Excellent thanks you so much

My only negative comment is that you did not specify what readings you got for each test. Why not?

what page shows the correct readings for r1+r2?

Nothing like an instructor giving a demonstration with his back to you and you can't see what he is doing, maybe I could do a corce at his college and I could then a job and no one would be any the wiser weather or not I have done it properly

, please don't use this method for your exam or for your job !!!

Don't forget the line conductor on the programmer between terminals 1 & 5. If you don't install it then the room stat won't work, it is shown on the diagram

Check the diagram for the DOL starter, they deliberately wired it L3-L2-L1 on the incoming side to the isolator and because the contactor is pre-wired, they swap it back to L1-L2-L3 between the bottom of the isolator to the top of the contactor

Had AM2 last week...They asked me to lock off on the 3 pole isolator within the DB, so you prove dead on the load side, not the supply side

Good video. What is the preferred method for terminating SY cable in an enclosure? Should the 2 brass washers be inside the enclosure or external? The reason I ask is that clamping the braids inside an enclosure can be tricky. Also would you confirm that colour identification is not required on black SY conductors as per BS7671? Numbering is allowed instead of colour identification. Also are the legs of the RFC required to be labelled/identified? If yes would one label them? Are the main protective bonding conductors required to be labelled inside the DB? Is it OK to ask the accessor to carry out the phase rotation test at the isolator before putting the cover on to conduct the Zs test? This would save some time as I would have to remove it again adter completing the Zs tests. Thanks

Can't see where you are connecting your tester

SuperDave 💪👍👌

Hi Dave, thanks for doing this. We're just at the point of researching what the art of the possible is for our training delivery and this has been very helpful.

Good effort, can you please make this video with zooming the camera and showing all wires and tester reading

👍

Good video, good process. One (pedantic) possible improvement could be to reverse the test sequence, i.e. start with N-E an end with the Phase to Phase. We had an instrument blow up the resulted in serious injuries for the engineer. The otherwise undetectable fault in the meter would possible have failed with less fault current if it had blown on Phase to earth. Good to see you are testing for dead without testing on a 'known live source' though.

What a beast

This video is a joke. Should've nulled his leads before he started, should've done a safe isolantion before doing anything. He is removing live and cpc conductors while MCB and main isolator is ON and LIVE. Didn't flick the light switch ON and OFF as he was doing his r1r2 at the light circuit. Used a bloody painters ladder. Didn't null the crock clips before doing end to end on ring. IR at 500V he tested between the Live and the entire Netral bar instead of removing the Neutral from the circuit in question, while still having a bulk head with a light still on above the dis board. Don't do what this guy is doing under exam condition. You're bound to fail.

Good video

Surely you check at every point on R1 + R2 test and switch the light switch on and off to prove polarity

Ok but as said show results

Great work e5 and Paul Meenan

Correction: in the video we mention a Main Circuit Breaker. This is the Main isolator.

Can you confirm the switching of the light switch(s) is required for safe isolation or was that for insulation resistance testing? I take it learners have to do both single a 3 phase isolation procedures and are you suggesting they make learners do the lighting circuit as the 230v circuit to be isolated? Thanks Gaz

Can't wait to come and see you guys, should be a great day!

Wow thanks lads we are very excited.... roll on the 5th of March 👍. Keep up the great work Gaz

mate, I can see that you're working live

where are live tests?????

As clear as mud unless you’ve prior experience. Crap.

Hi mate great video but could you please do one more in depth, demonstrating how youre setting up your megger for each test and explain the purpose of each test phase of cripper. Thanks again.

Very helpful, thank you. Just what I needed as a quick refresh before my exam tomorrow.

How did u get those results, the first three tests the main switch was on except for the last one, doing my practical, at college and just noticed it

Would be great if you'd show the actual meter settings and the readings you get. What you appear to be doing here is just enacting the CRIPPER testing sequence without actually showing much. Sorry if I sound negative, but thanks for the vid. ;)

You look like a fucking eagle

Hi, could you please do a video finishing the sequence with the live tests

Good stuff. Please can you do the "live" tests in a future video?

Well done dave please could you let us know what setting the testers are on every test, good luck

1st test is. continuity of protective conductor (disconnect cpc from met) 2nd test is. continuity of main and supplementary bonding conductors (disconnect cpc from met) 3rd test is. continuity of final rind circuits (no need to disconnect the cpc from the met)

Thankyou v helpful
