No L-L end to end on ring main

[Mspark2987]

Hi everyone hopefully someone can shed some light.

I'm doing an inspection and test and upon testing my end to end for the live on a ring main I've found there is no end to end on the live. I've tested at sample socket and at the board. I got an r1 + r2 when interconnecting my lives and cpcs and a Zs. Just want to make I'm not missing something obvious. It's not my test kit as I've already tested two other ring mains

Thanks in advance

Hi, welcome to the forums,

The obvious answer is a break in the line conductor somewhere. Break the ring down into half and test each half, break the faulty half down and test, continue until you either find a bad connection out a faulty leg.

Are you getting continuity of rn?

 

[Rpa07]

Did you originally test for continuity in a different place that you tested your figure of 8 test? If yes then the fault was where you 8’d, if no then you need to break it down as Sparkychick suggested.

…….or, if your just testing, report it as a fault and do your fault finding when given the go ahead.

Think about it, its a ring final so you will get an R1/R2 value and an internal loop impedance

Connect live and CPC of one leg. Go around and test R1+R2 at each socket outlet. At some point you’ll get an open circuit. That should narrow your search down. If necessary repeat on the other leg.

How can someone who is doing an inspection and test not have much of an idea of how to fathom out why it has failed?? Answers on a postcard.

Just a joke - I know you’ve been a good boy and just lurked, biting your fist at certain times!

I've only been banned twice actually. nowt much changes though! I thought people doing I&T were supposed to be of a certain sort of experience level? Just saying.
