I’ve got the LAP one and I use it quite often. It’s shown me that on an inverter there is a live/neutral reverse which is pretty weird as you’d assume that live and neutral would be wired as per say as they come off of the battery used on the inverter
2:02 Ring circuits are only permitted in the UK. Only radial and branch circuits are permitted worldwide. In the UK a ring circuit with 32Amps is used. In other countries this is 2 lines with 16Amps. I don't see where copper should be saved, only that the whole house depends on a single fuse. When the ring is open the fuse should be reduced to 16A. But this is a problem with ring circuits and not the fault of the tester for radial circuits.
Hi Jens interesting comment . We use rings in the uk mainly for the kitchen circuit . It would have to be wired in at least 3 radials of the same sized cable . 2 x 16a radials in the kitchen would lead to circuit breakers in a state of over current so copper has been saved . It also saves on fuse board ways .
I think you will find Dubai and Abu Dhabi now permit ring circuits, generally in a normal sized house you would have two ring circuit's, one for the kitchen and one ring circuit for the rest of the house.
I have this LAP tester and yesterday I used it to wire up a single socket onto the other end of a radial. It reported "live earth reverse", which had me scratching my head for a bit, but the issue was actually missing neutral (had come loose from the neutral bar in the consumer unit). But at least it told me something was wrong, I possibly wouldn't have realised otherwise until I came to use the socket and had a problem.
Indeed, for all such Socket Testers, a Neutral / Earth Reserve wiring mistake cannot be detected, it has to be visibly identified, nonetheless, it can quickly sort out unconnected /or broken or dislodged wire inside a socket. This device is only a tool to assist.
Hm, obvious when you see it, but not something I'd considered. Leaves you with an interesting dilemma given current guidelines mean DIYers aren't able to open the consumer unit in order to do a ring continuity test from there.
Yeah good point, you can do a ring continuity test at a socket with a multi meter, then you just have to make sure those cores are tightly in the terminals before screwing the plate back on the wall. Thanks for watching!
The danger of 13-amp socket testers is the neutral earth reversal that cannot be identified by the tester, particularly in a TNCS installation, you need to buy the type of tester that has a trip button and test each socket to ensure the RCD trips, alternately you need to check each Socket for the connections,
My sockets tester has a button , when socket tested ok i.e Two Green LED to the left, And by pressing the button power goes, Does this mean Socket is still Ok? Thanks.

That is odd, thanks for watching!

Thanks for commenting on another video!
Yeah I agree socket testers are still useful, I was mainly highlighting the ring issue

Wow. I never knew that. Quite a useful bit of information.

How do you do a ring continuity test with a multimeter? Great videos, thanks

Neutral earth reverse s possible only if there is no RCD. With an RCD it would cause immediate tripping if the socket is used.
Thank you!
You're welcome!

That is the RCD tester. The power should go off with it. You then must reset the RCD.

Good explanation.
Glad it was helpful!
Nothing worse than having a broken ring.
Thanks for watching!
Very informative
Thank you!
All these lap testers show is a reverse in something always, I think they’re rubbish
Interesting
Thanks for watching Billy!
