Great video,John Ward also does a good one on the same subject where he actually creates connection problems on an extension plug and tests them with a socket tester,he says if your electrician uses one of those it's time to get a new electrician lol
I see no issues here. They're an indicator that do have their purpose in the work place too. I went to a recent job as customer said socket didn't work, I plugged in the SOK32 tester and found the switch wasnt working but it also highlighted no earth. Traced back to a JB and no one had connected the earth. Someone else may have just changed faceplate and carried on with no earth.
That is exactly what they are good for. However, they don’t show neutral/earth reversal, so the only way to prove polarity on a socket is with R1 + RN and R1 + R2 testing. Which technically, you did not test for.
You talk shit.... A electrician can run around a 3 bed house in 4 mins using a GOOD socket tester and very quickly have a idea of thing related to the basic rings, spurs and radials etc .It saves a huge amount of time .Then they can go to town when issues are found
Adrian thanks for the video, but as someone who has no practical electrical knowledge (thankfully no physical one either!) I am still somewhat befuddled. Say I'm a painter/decorator on a big job and I've had the site electricians telling me that they've isolated the rooms that I'm working in so that I can unscrew/detach the sockets and ceiling bulb fittings to ensure a clean paint over. How can I check for myself that none of these points are live? Assuming reluctantly that said electrician/s might have gotten it wrong, or perhaps they isolated the wrong room?
These are alternatives to no test. A user can verify his sockets with them. These never are alternatives to a proper test made by a professional. These can also be used by other professionals than electricians who may need to use the sockets at the customer's house. They may be more relevant to countries like US where old sockets had no earth and could not use earthed plugs. Many just changed the sockets without any knowledge of how to do it safely.
How do we test for a reversed external L & PEN conductors in a single phase installation, given N&E within the installation will both be at the same potential and at a potential difference to L of 230v? I personally can’t think of many testers that would pick this up. I suppose we could use a temporary ground rod to check voltages against but I’ve not seen this done. I know the 1700 series Megger MFTs have some sort of voltage detection to their cases to check for voltage wrt to yourself but not everyone owns one.
Not to panic, I’m qualified. I’m referring to the paperwork at around 4min in. It is basically saying it’s a limitation of a plug in socket tester but IMO why should they be singled out for this when even a normal polarity check won’t show an issue where the cross connection is outside the property?
@tim g Personally I can’t see how a reversed L and PEN externally will show up even using voltage indicators or a loop tester, I.e if the N&E terminals are at equal potential and the L is at 230v wrt them, but N&E terminals are 230v above true earth and L is at 0v wrt true earth.
@tim g I agree with the idea that it shouldn’t happen if the DNO are doing their job right, my problem is more with why to single out why it’s an issue with a plug in tester?
@tim g some of the old approved voltage indicators are not much more than a lamp or a coil, I still fail to see why the plug in testers are being singled out for criticism for not being able to detect a reverse L&PEN fault when nigh on all our testers can’t do that either.
@tim g I’m specifically referring to TN-CS, with TT and TN-S an external reversal will show up with normal testing. With TN-CS the PEN enters the premises as a single conductor, separating out in the cutout to provide the neutral and the main earthing conductor. If for some bazaar reason the L&PEN were to be crossed outside the premises or in the cutout I still don’t see how our normal polarity / loop checks will show it for the reason I said above.

I haven’t seen that one, I’ll have to take a look 🙌
Thank you for the recommendation 👌
Great video You knocked it out of the park Adrian. I will let others discuss over other more bizarre scenarios regarding tester capabilities.
Thank you
I read this pamphlet and it was really interesting. Thanks for video and article.
You are very welcome
Thank you for your nice presentation and I do learn a lots from your video
Thank you 🙏
Good video, thank you!
Yes you can test for N and PE reversal. just push the RCD test button. if does not trip, reversed.
Thank you

@@Pure_electrical_training had know reason to test for it, for a socket that just wouldn't switch on!
For a _normal user_ like myself that socket tester(preferably with RCD test) is fine.
If an electrician uses one of those just show him/her the door.

The socket tester should provide a way of checking the sockets for power, you would need a voltage indicator and a lamp adapter to prove the lights
@@Pure_electrical_training thanks again, will probably try them out

I used it like a fuse finder as 9/10 cu are labelled incorrectly.
