very high r1 result!

[HappyHippyDad]

Afternoon all..

I have just been testing a ring final circuit and got r1 = 107Ω

It is TNCS, rN is 0.4Ω

I'm sorry I haven't got anymore results for you, I'm nowhere near home at the moment and those are the only 2 results I can remember.

This is on a kitchen ring and the Kitchen is being ripped out over the next week and I shall be reinstalling a ring in the new kitchen. This will be a good time to find any fault but...

My question is what could give this kind or result? 107 is huge! I initially thought loose connection, but even if the conductor was just brushing the socket terminal I would have thought it would be far lower than that?

Thanks..

loose connection been arcing and gone high resistance?

Were all appliances on the circuit unplugged or switched off?

how could appliances affect the r1?

About all it could be or a screw through the live conductor.

What was rn?

Sorry.. Have corrected the OP rN=0.4Ω

Sorry.. Have corrected the OP rN=0.4Ω

I'm still sticking with Tel's suggestion.
