r1 r2 through conduit

[nicsin02]

Hi guys, as the title suggest how do u test the R1 R2 value or R2 continuity if the sockets are earthed via the metal conduit?

Thanks guys

 

[Silly Sausage]

In the usual way.

 

[nicsin02]

What about continuity?

Sorry to answer a question with a question but what about continuity?

 

[nicsin02]

What would you write for continuity on sheets when testing continuity at the sockets?

You've completely lost me now. So you've got the r1 cable and a metal conduit - think about it.

nicsin, I take it you haven't got a problem with R1 & R2 on a circuit wired in T&E.
Conduit (or Trunking) is just a conductor like the bare core in T&E, nothing magical or mysterious about it!
Remember, you'll invariably get much lower R2 readings than T&E.

Much, much lower!! lol!!

Much, much lower!! lol!!

That'll depend on who installed it.

Yeah but normally you would separate the c.p.c with twin and earth and measure between??

I know I'm cracking on a bit and do tend to have senior moments but I'm sorry to say I can't see what the problem is.

Very true in this day and age!!! lol!!

I was assuming though, that it was installed by a tradesman that was proficient in installing a conduit containment system....:smiley2:

If your only cpc is the Conduit then you cant do a R1 + R2 due to parallel paths. Take your R1 inspect teh the conduit throughout and prove conitnuity.

If you have a seperate cpc within and you can isolate the cpc throughout from the Conduit then yes you can record a R1 + R2.

Take a Zs reading at the socket and thats about it.

Total lack of experience is the culprit here!! These day's if it isn't T&E or SWA installs, the head scratching starts!! lol!!

Or you could hire a Ductor that delivers 25amp to test the conduit
