interconnections on ring how to carry on

[domn]

at a job today i tested the ring to make sure we can extend it phase .31 neutral .34 and earth .24 r1 plus r2 at ..13 so that checks out ive checked for interconnections and think its going to be at jboxes under the floor (it's a bit of a diy house )
whats the way forward as customer doesn't want floors lifting etc can i just note on cert that the readings are not what they should be but still safe etc
i also found a bit of 1mm connected into the back of the cooker switch cpc snipped off ran to a metal cooker hood pushed through a drilled hole and quite frayed not the best

so you`v got an r1 of .31...an rn of.34 and an r2 of .24?...well, theres something wrong then there straightaway...

 

[VoltzElectrical]

really? Why?

 

[domn]

i know that its wrong ive checked the ring for interconnections and it looks like its been done in jboxes under the floor the customer doesn't want the floor lifted to find (sorry just read what i posted i ment that the r1 r2 test confirmed the readings from the end to end test) really just asking about recording and carrying on

With an r1/rn of .31/.32 i would be looking for a r2 of around .51?!.......something not quite right there

Yes but it usually a high r2 thats a problem.

Ok its not the expected reading, there's some form of parallel path thing going on, you didn't install it, the reading(s) are BETTER than could be hoped for. Whats der problem

 

[domn]

i know its better than expected i was just a bit unsure if i would have to make a note on it because its not what was expected if you know what i mean

the problem is....theres a high resistance on both r1 and rn.....

 

[dagrat]

Not necessarily, the R2 resistance is usually higher granted, however this is an existing installation and there are probably other parallel earth paths. If the R2 was higher than x 1.67 then further investigation would be required

Good point glennspark !!

Hmmm....
