QR code 12 -- Prospective fault current test

[@igdaroak1288]

Thanks for clarifying my doubts about testing, very informative video. Many thanks

[@TBIRDS1000]

When testing live, its always good practice to put your test leads first on the non live conductor and then to a live conductor don't you think? I know you cant do it between phases but between earth / phase and neutral / phase should always be.

Measuring tools of this brand and model Can the short-circuit current be tested separately between L and N and L and PE?

[@chriskitcher]

Hi I think that you mean 2.28 and you are perfectly right, it does show me putting the probe on N when carrying out the L3 to E part of the test. I think it may have been a mistake when the video was edited and the wrong section of the video was cut in. Thanks for pointing it out though.

[@dimitargetsov9690]

from educational point of view perfect clip -so many mistakes the viewer has to corect himself,learning.

[@codecageadmin]

disconnect at the DB and at the first light and mega your cable, disconnect subsequent connections between each rose or outlet and do the same until you find which run is crushed...etc

[@Kitchentotaste]

On which side you should put tester leads if main switch off?. That was a a question on 2395 exam.

[@train4905]

Exellent demo sir

[@codecageadmin]

Chris, firstly great videos!, can you possibly do one for testing from a main db to a new installed db1? i'm not entirely sure where to get all the values for the installation certificate from in this scenario, the information doesn't exist (or i can't find it even in your book). I'm sure many others would appreciate it.

[@gregsmith5553]

This is the 1st video I have seen which says all MCB’s and Main Breaker should be turned on to get all the possible parallel paths and fault conditions which makes perfect sense to me . However other video’s , demonstrations and even of Sparkyfacts it states the Main switch You be off and you test to the incoming side of it! So which is it Mains Switch on or off? finding no guidance on this on any publications.

[@dalematthews8748]

Great video but I don't understand the idea of parallel paths that would increase the value, what parallel paths are we talking about 🤔

[@jacklyon4934]

did anyone else notice when testing L3 to earth he actually tested between L3 to neutral? good videos though. :)

[@dimitargetsov9690]

yes sir.and that black cables terminal is under any colour code NOT earth!!!!!

[@loveanunity6277]

Lo yea I clocked that puzzled me for a second

[@kevinmarsden8102]

Thanks Pacman. I corrected him on another electrical video which he blamed on how it was edited ? I personally would have watched all of my final edited video before putting it on internet :)

[@simdude2u]

In some load centers the ground & the common is combined.

[@kevinmarsden8102]

At 1.37 he says about going onto L1, but he puts it onto a blue (neutral cable) Please could someone explain this.Thank you

[@niallers8572]

He made a mistake he meant to say L3. The old colour codes are as follows L1 red, L2 yellow, L3 Blue (hence the blue conductor. Neutral was Black and Earth was Green. The current colours are as follows L1 Brown, L2 Black, L3 Gray, Neutral Blue and Earth Green and Yellow. I hope this helps make sure you know your stuff before attempting to this stuff you need to know the old colour codes they are just as important, as you may have to do a periodic inspection and if you were to mix up old L3 Blue with current Blue neutral or current Black L2 with old Black Neutral it could be fatal.

[@michaelbyrne7128]

Kevin Marsden That is not a Neutral he is testing on that is the live side of an rcbo which has neutral tails, I can see where this looks misleading. He is testing on L1 but on the 3rd one down (3L1) rather than 1L1.

[@muhshij8130]

Can anyone help. Im doing a fault finding in a lighting circuit. How do I find where the neutral is touching the live. All the wires look fine so im at a loss

[@pkmpkm7113]

Max short circuit current would be a fault between L1 L2 L3 ?

[@shahzadhashmi1454]

is this for low voltage system ? or this also valid for MV / HV systems ? as u have mentioned its a live test , so HV 132kV how we can make connections ? to me its very dangerous. plz advise . thnx

[@kevinshere67]

At 5.28 on this video he says he is going to earth but it shows him putting his test lead on the neutral bar. Can any one explain please.ta

[@richierich8334]

Would be good if father time wasn't using a tester as old as he is.

[@shahzadhashmi1454]

Prospective current is same as Full load current of the system or conductor ? bit confusing . there is another assumption we make is Max. Fault current level . i m lost ... need some guidance. any one ???

[@alansevern290]

Also at 2:30 he says "blue phase and earth" when he's clearly measuring between L3 and Neutral as can be seen, what a wally. We are trying to get it right for our AM2 exam and here is a 'professional' showing us incorrectly!

[@markgilder7757]

Blue was and still is LIVE 3 Phase supply, Black is Neutral, Hope you do not come across any old coloured installed boards, you're gonna hurt yourself "Wally"

[@marlonw6236]

@@markgilder7757 No, he goes between L3/blue to the neutral bar when he should be going from L3/blue to earth bar

[@francescofrusteri1139]

Hi Sir, minute 2:28 i think a mistake was done. You are measuring the PFC between live and neutral , not between live and earth .

[@DstandsforDoomed]

Poor video sorry. I hate to be a critic but there’s too many “not quite” bits here

[@beardedsparks2825]

Shut up
