R2 test on a ring main where the conduit is the earth

[VoltzElectrical]

innit do bruv

 

[VoltzElectrical]

so what your telling me thats too low a reading is it??

come on kev, low readings are what you want on R1, R2 testing. Think back to your time in college, ohms law and all that.

Yea i know that yea just wasnt sure about R2 testing thats all whether to expect such a low reading for it, but what is Telextrix talking about,

Low readings on a conduit system R2 reading is what you want and the reading you got was fine. remember its a big lump of metal and a high reading would indicate bad joints!! and a bad joint really aint what you want.. Telextrix pass round what ever that is

your colloquial expression.

What fault are you trying to find on the ring circuit? What R1+R2 did you get for the circuit?

Ahh ok , didnt do the R1+R2 test as there was no CPC running in the conduit the Ringmain CPC is the conduit so had too do the R2 test instead

 

[Knobhead]

I’ll tAk a tote on dat az weL. A weL mAd conduit SYS wiL alwys beat cabled systems w separate CPC.

 

[VoltzElectrical]

are you just testing this circuit or trying to fault find?

 

[VoltzElectrical]

so how are the sockets earthed then? surely you can link Live and earth at the db and test at the socket?? How are you gonna do a Zs then big boy?

 

[Kev2632]

On this circuit there is no faults just testing

 

[Kev2632]

Yea there is a earth cable coming from the box to the socket and i will be able to do my Zs then as the socket are earthed

 

[VoltzElectrical]

I would have just done R1+R2 and saved myself all that hassle!

 

[Kev2632]

So it's still eligible to do the r1+r2 test on the ring main where the conduit is the CPC yea? Just link at board and test at each socket yea?

 

[VoltzElectrical]

yeah man!

Thanks
