[@michaelhaile6579]

Great videos garry but can you please do video explaining types of tests and what it means to the circuit. Your help is greatly appreciated.

[@TF-uo5cg]

Love the content gents! Quick question this is under unit 204 level 2 but in this video Gaz mentioned it's for level 3....

[@danielteyehuago1633]

Thanks for sharing it with us

[@Andy-i5g]

Excellent

[@MrSJT]

Something you could add... if when you do the R1+R2 after doing the R1+Rn, if the switch doesn't switch off the second time round, it would have meant (pending on other tests) that it is highly likely that the switches are double pole and only the neutral pole was switching off

[@t33bee8]

Great video. Thanks

[@GSHElectrical]

Thanks 👍🏻

[@eurotropia]

Hi, A few (maybe silly) questions please as I've never done testing before, just learning now. - Do I need to disconnect everything from the sockets before testing? - Do I need to switch ON or OFF the sockets each? - What if there is fused spur on the ring? My boiler is on the ring of the living room sockets. What should I do with it? Many thanks for your answer in advance!

[@regdor71]

U guys are amazing thanks a lot

[@GSHElectrical]

Thanks 👍🏻

[@gabeerlazem7798]

Thank you ❤️

[@martinhenrymh89]

Very good 👍

[@GSHElectrical]

Thanks 👍

[@FixItWithJon]

Great video, thank you for sharing 🙏 When you were checking the spur did you probe up onto the input or did you switch it on & probe on the output?

[@GSHElectrical]

Outgoing and operate the switch… our spur had NO outgoing circuit 👍🏻

[@GSHElectrical]

Can you test at the outgoing load from the spur…?

[@FixItWithJon]

@@GSHElectrical Yes - it's awkward for some, but I can just about. I was just thinking that the load will affect the resistance reading..

[@johnburns4017]

Taking the resistance from the sockets when the whole ring is one continuous conductor made into a loop. The L & N in the socket may be at opposite ends to the loop. That is, if the loop is 100 metres long, the L & N in the socket will be 50 metres apart on the one and same loop. So the measurement is right around the loop? Hence a reading of 0.5.

[@CommercialGasEngineerVideos]

Thanks, good video

[@GSHElectrical]

Thanks for watching

[@budzshawn]

Great content. Where can I get a replacement motherboard for a megga insulation resistance tester? Where do they sell replacement parts?

[@FrazerSimmons-w4t]

How would you identify what legs are part of the ring? I’ve noticed you marked them with a black pen, however say if it was in singles. How would identify the correct legs of the ring?

[@Mok-l5i]

Thanks for help

[@neilmac991]

Great video . Hope thats not a euphemism "marcus gone to take kids swimming"

[@GSHElectrical]

😂😂😂

[@davidb3537]

I noticed Marcus used the tips of the crocs when connecting to the conductors, my cps assessor has questioned me twice on consecutive visits how I personally carry this out, if I use the tips he says the spring end gives a better connection and visa-versa on another visit, personally I don't think it matters so long as the contact is good, what is your opinion?

[@GSHElectrical]

You make some great points 👍

[@Hussain-w9k]

Is a ring final and ring main the same thing as a ring circuit just different wording such as earth conductor/CPC etc

[@17italyman]

you said in the AM2S theres a fuse spur which goes to a outside socket,when testing at the fuse spur could you not put your probes onto the load side of the spur and click the switch to confirm polarity as well and then test the outside socket like normal ?

[@ben8878]

How have you nulled the leads with the plug in leads?

[@db-bv5rs]

On a ring you can only spur one and if you want another one you need an fcu. This is because you could potentially draw more than 26amps correct? However, with radial circuits does this reg come into place because before you can draw more than 26amps the 16a mob should trip correct?

[@Apathy2271]

yeah mate

[@tommcconnell69]

Are the readings coming down because you've sprayed the plug top and loosened the contacts or just because the liquid is reducing the resistance in the contacts momunterely as it is aiding the flow of current with the plug top being wet ? Just a thought.

[@miketv8718]

Fantastic video, I’m not an electrician, both yourself and JW state on the figure of eight test between the line and cpc should be higher overall due to the thinner cpc but all substantially the same , but the on site guide suggests increase or decrease measurements depending where you are on the circuit?

[@burningdevil12345]

The on site guide is correct. I tried explaining this to my tutor and he didn't accept it. When you draw it out it makes perfect sense. (r1+r2) / 4 works when you're half way around the ring. As you move along, you will have more cpc on one leg and more line on the other. So the overall resistance decreases as you move towards the ends of the ring

[@teed1]

I am a bit confused as a new student bit at the end of the test in front of the white board with Marcus, you made the note as r2 1.67 i thought that was spouse to be cpc end to end reading why did u put there 1.67 as r2? thanx

[@leeedwards3783]

Thanks for the video gentlemen. It is really helpful to so eone like me who is very interested in electrical installation and hoping to get into this line of work as well as my plumbing and heating. Seems like it is just as expensive as plumbing with the tools and calibration etc with flue gas analysers and multifunction testers. Is it better, cheaper togo for individual testers or better for the multi function? thanks again

[@Apathy2271]

multis are expensive but its an all in 1 unit. alot easier if your main job is testing

[@daron8982]

when do you do small r1, rn, r2 test and when do you do big R test?

[@davidharris8885]

Thanks 👍

[@Dogandhorselover]

after getting r1 0.62, rn 0.64 r2 0.93 end to end, on cross connection what would make you get a figure of 0.00 at socket points?

[@MaxEpsom]

Hi Just came cross job i tested at CU and found r1 higher than rn on 2.5mm cable i didn't have time to investigate can you please advise im going back next week. Thanks

[@rgodhnia]

Great video but it was very fast to understand slow stpes would help to understand better

[@GSHElectrical]

Thanks for the feedback 👍🏻

[@shannonj1000]

Hi I am a huge fan great video as always, a little baffled by calculations.. 1+ 1.67 / 4.. same with other calculation.. can you advise

[@17italyman]

also you havent said anything about nulling the resistance of the leads when you used the plug in tester,is this something you need to do or not for the AM2S?

[@GSHElectrical]

Remove the resistance of the leads

[@hussainali-bb6nt]

Hi Gsh electrical currently am on second year ( actually 3rd gear ) covid 19 messed up every my learning. Questions how to remember to do ring circuit in order

[@calebbrookes7896]

Do you have to do it in the board or can you do it in any socket in the ring circuit?

[@GSHElectrical]

Any point on the ring final circuit 👍🏻

[@calebbrookes7896]

@@GSHElectrical I thought so but I was told it has to be at the board so that the tester won't pick up any parallel paths from other earths or neutrals?

[@Hussain-w9k]

Aren't we supposed to carry out isolation, before doing continuity?

[@stevespoor6567]

Doesn’t the fuse in the plug cause any issues with the readings? Or is the assumption of a fuse being in the plug incorrect?

[@Apathy2271]

there is a fuse. but it should only act as a fuse and should let the current pass with no addition to the resistance reading

[@brettstewart4118]

[@montystelevision3238]

These guys are quite selfless. They probably earn less as a tutor delivering the gold standard than working out in the field on the tools. The college looks cool and if it wasn't for distance I would be wanting to do my 2396-01 here.

[@GSHElectrical]

Wow thanks for that amazing compliment 🙌🏻👍🏻…

[@lordali1034]

Do you need to make a temporary link?

[@GSHElectrical]

Use a connector 👍🏻

[@craigrollinson3326]

Great video, did you mean to say 0.05 when the reading and calculation was 0.51. I have confused myself

[@MARTINA-gc3tq]

What would be a better lesson might be to show how to split a ring into 2 properly fuse rated radials.

[@Benm32]

can anyone link me to the earlier learners video they keep talking about? I'm still early days and I'm a little too dumb right now to understand everything in this one. Thanks!

Joining the opposite L and N in the connector block makes one long single conductor joined at the ends. A loop. I don't think that was mentioned. Could be wrong.
