continuity of ring final circuit

[angus65]

Hi

Just doing end to end test

line - line 0.51ohms seems fine

cpc-cpc 0.91 ohms seems fine

But N- N reading is coming up 1.46 Kilo ohms ??!!! any thoughts

I am doing 2392-10 and am fairly green.............be gentle

Poor connection somewhere on your RFC?

 

[Silly Sausage]

Dodgy connection.

addition...

Beaten by seconds...again!

Are you sure you getting 1.46 kilo ohms? and not 1.46 ohms?

Either way mate it's a bad connection

 

[SirKit Breaker]

Definitely as above.

I have had similar, and all it took was a half turn with the screwdriver to go from about 500 ohm to about 0.45ohm.
Fortunately, it is just this easy sometimes.

it's finding where to use the screwdriver that's the hard part

yeah definatley a bad connection had a line-line the other week when checking for a kitchen fitter, 4.46ish k ohms. Turned out to be a poor connection and burnt out in the back of a socket.

probably is a bad connection but was just trying to highlight the difference between 1460 ohms and 1.46 ohms

Depends where you're testing.
I&Ting hotel bedrooms once, virtually every room the RFCs had bad readings and just about every socket we removed to look at had loose connections or just pulled out completly. The manager was not happy, only rewired a few years earlier. We left him digging out the installers details.

 

[GLENNSPARK]

go round the ring....check ALL joints....retest...

 

[Octopus]

As above, the only way forward.

 

[angus65]

Thanks for all your input .Definitely KILO OHMS!!.HENCE THE THREAD.Will be checking socket outlets tomorrow

Not always a bad connection, had it before where the installer had twisted the conductors together and it had broken, giving a high end to end reading. More often than not it will just be a dodgy connection.

Just gotta hope it's at a socket and not a JB under the floor!

Is this a question in theory or something you have just come across in the field?

 

[angus65]

loose connetion in socket outlet .Sorted .Thanks again
