- Student training aid for testing continuity of CPC and polarity of our A3 radial socket Circuit. Remember to test line to neutral first as part polarity then line to CPC to complete polarity and gain your continuity reading R1 + R2. Using a MFT Megger tester during the practical demonstration.

Great video, very clear and concise instructions and reasoning behind the test. What do we call you, you never give your name in any of the videos.
Hi. Click my Facebook link in any of my videos and you can follow me and my learners on this years journey at college. Thanks Gaz
Learnt more in a week of binge watching your videos than a year at college
Wow thanks for watching and commenting glad I could help 👍
College a joke I used go to college they don’t teach u much u got put u own time in and study and practice
Quality.Keep it up Gaz
Really helpful video great explanation u are quality lecturer
Clear, informative and very relevant for the next job in the workshop, cheers. 👍
Have a good Christmas and I look forward to more informative videos in 2018.
Great video gaz. Big help
My practical tutor
Great video again 👍
Greatvas usual gaz.. Many thanks
Amazing video
Thanks
Great video gaz
Came highly recommended from my practical tutor who thinks you're amazing btw
Massive thanks for the support and watching 👍🏻
When I made a test board back in the Mid 90's I put heating element's in to make it look like much longer wiring. Also a on the back was a socket were we plugged in a plug with just 1M 2M 500K resistors in with a rotary switch we had 3 ( one with Live neutral ) ( Live / Earth CPC ) ( neutral CPC ) that was for insulation testing - We would have a light switch to switch in and out on each L & N a heating element or just a long wire of 20 meters to make it look like a bit of a loos connection on the L or N only so one side would be a much higher test reading.
This Channel has helped me loads, thank you!
Hi. Fantastic 🙌 I am glad GSH has been helpful many thanks Gaz
Yes it has I must say, recommended this Channel to a few people aswell, still along way to go on my courses but I’m getting there !
Thanks...great video by GSH You guys are amazing. I have learned a lot on inspection and testing videos.
Masoma Danish thanks 👍
Very interesting and helpful 👍🏼👍🏼
Great demo Gaz. Thanks for he efforts.
When u test the ir from neutral to earth you put it on both bars. On the screw that clamps down the circuit being tested but all the other circuit are in situ do how is that an accurate reading of the individual circuit neutral n earth? It seems like u would be testing the combination of all the circuit neutral to earths that way. Having said that if there were to be an issue of a low reading would u then pull them out to isolate them directly from.thr bars??
Hi Gaz, I wonder if you can help me. I have a length of twin and earth in a roof void. I think it may have a break in it. The cable is fixed so I can’t get to join it, but can get to both ends. Thanks.
👍👍👍👍👍👍👍👍
Thank for the great videos. A simple question please help, why are you showing Live terminal on the socket plate located on the right handside?
when we open a plug we see the live pin is located on the right handside, but when we plug it in, the live will be located on the sockets left terminal.
isn't that how it is?
No. Live pin is on the right.
Don't forget, you are taking the top off of the plug.
👍👍👍👍👍👍👍🙏 supper
thank you sir
Your welcome
On my assessment for 2394/95 I have used a crocodile leads to zero tester leads plug , but knife looks much seriously ;-)
I would like to see a socket on there that you know is wrong - We can learn also from a wrong reading an how to find it. Not just only seeing how it should all be - Mr DID going to B&Q an buying a two way kit they used to sell then going I know how to do it all.
If it s tns or tncs do you still need to do insulation resistance test between earth and neutral?
Hi gaz, if the circuit was cross polarity, i.e in the fault finding exam, what readings would you expect? A closed circuit?
Furthermore how would you rectify if!
Thanks
You say you don't like the joint box which I agree with you. Just wonder what would be your favoured way if not teaching in a class room but in a real world scenario?
Forgive me but when you indicate neutral and live on the socket outlet should the live be on the left ? Amazing tutorial
Hi . The line is on the righthand side. Many thanks for the support and keep watching many more videos Gaz
Oh ok you are referring to where the cable goes into the socket and not the pin of the plug. Thanks
👌
How comes the left pin (neutral) is on the fuse and not the right one? (Plug test lead)
Hope your getting paid well merry xmas gsh👌
Watching the new Star Wars film 👍
What did electricians do without this bit of test equipment before it came along. Was a multimeter good enough?
No
Good video. Informative and instructive. Narrative is 'a bit quick' though.
When's Sooty or Sweep going to pop out on the other hand from behind the board?
Hi Great explanation there.
What is the max acceptable R1 + R2 value please
Hi. Depends on a number of factors: external impedance and size and type of over current protective device (fuse). Thanks for commenting and watching Gaz 👍
or, you could just invest in a martindale plug in test and save yourself a lot of time! Are these wondrous bits of kit actually deemed an acceptable form of testing CPC continuity and polarity for sockets though?
Holy shit! Do you have to do R1+Rn also? Thought it was just r1+r2
Same here
IMHO R1 and Rn is a good test to reveal loose connections and especially trapped insulation where wires are pushed in beyond where they are showing bare conductors before screwing terminals down. The values are not recorded on a test sheet but a significantly different reading between adjacent accessories will alert you to an unsatisfactory connection between the two points.
Excellent video...What does the term "A3" mean?
Hi great question.... Pass.
We use A1 for a ring final circuit, A2 for a radial socket circuit and A3 for a radial socket circuit with different considerations. Thanks Gaz
Just a broad overview

Cheers, that's much appreciated!
Lovely.
Can u tell me what extent of electrical work a non qualified person is permitted to do. I e could I run all wire's to relevant place and connect sockets switches etc thank u
Technically you could do everything you could install a socket or a distribution board the problem is you can't sign it off on an eic form and guarantee it's safe operation. If anything happens (fire,electric shock) and it's traced to you it could be manslaughter. I know it sounds a ridiculous but that's the rules. Being an electrician is virtually the same as gas safe that's why we have to keep our quals up to date. So my advice call a professional.
@@markdove5906 - How about notifying building control? Would they not come and check it? (notifiable stuff that is)
How many sockets can you have on a radial?
As many as you like. Ensure the protective device (MCB or RCBO) is adequate for the cable chosen. 2.5mmT&E needs a 20A, while 4.0mm can use a 32A. Do consider volt drop if the run is particularly long.
thanks for all the videos but don't make the excuse that you get a low resistance due to short cables. You're an electrician, go buy some resistors and start soldering them in.
Our low readings can be due to cable lengths say around 10m and the cable in a domestic installation could be many more metres longer. All our exam rigs have power resistors in them to increase circuit resistance/impedance all the best and thanks for watching Gaz
