Worldwide ring mains

[KevinS]

Quick question here, does anyone know if any other countries use ring mains
reason I ask, I have made a proto-type socket where you can do your continuity checks and r1+r2 tests WITHOUT taking the socket off.
i don't know how much more money and time to spend on this idea

There was a post on this a while back, Not that many I don't think, mainly limited to (former) British colonies. Engineer54 could help with this.

What is special about this device then that you have designed?
Not being funny - just interested

According to wiki, the UAE, Singapore and Indonesia use ring final circuits.

Sort of like a breakout box ??

Look like an ordinary socket from the front
without giving too many details (as I'm uncertain as yet about going through the costs of patenting the idea)
when you do your circuit impedances at a socket it is possible that one of your wires may come out when you are putting the socket back and therefore the circuit is in a worse condition than before you started.
With my "device" all measurements (and future measurements) will be done with the socket cover in place. No removing sockets, no disconnecting wires, no joining your lives and cpc's together to get get your r1+r2, no putting it all back together

....also no checking terminations are tight?

What's wrong with the plug in socket mate and plug your meter into that, ok we still have to link l and cpc, set up figure of 8 testing on rings but I don't see this way as a problem.

 

[alarm man]

is it a plug with a bit of flex on,speak to page 4 he has loads of devices like that,

 

[KevinS]

You would know that your terminations are tight by your readings, because as I said the readings are taken once the socket face is a place

Kewcheck R2 Socket Adaptor - R2 - Test Without Removing Wall Socket

I just use one of these, no taking face plates off

Sounds like the idea is you fit this "different" type of socket to all the outlets and leave it installed? Maybe it has some test holes in it or something?

 

[KevinS]

A plug in socket doesn't tell you what the impedance of you live, neutral and cpc are, you need to BREAK the ring to get these, and has one of the conductors never "popped out" as you are putting the socket back. How many have come out and you have not noticed, therefore the ring is no longer a ring. With my 'device' as the readings are taken place after you fit the socket front, you would know if one of your wires came out as you would have an open circuit and know immediately
ps no disrespect to your or anyone elses workmanship but it can very easily happen

so the other 202 nations on earth are exculsively using radials lol.

So this is simply for testing after you have replaced a socket, to ensure that nothing has "popped off"?
I realise that good readings will indicate that there is decent contact, but nothing really beats checking an old installation with a visual and a tweak of the screws. Maybe I'm just old fashioned
