Issue with r2 reading on ring final circuit due to parallel paths
Good evening,
Been on and off on this project, they’re all brand new flats and now I’ve come back to carry out EIC tests.
It’s all first fixed in steel conduit and have stud frames with caddy clips on, so naturally been told to earth back boxes. Before I left I mentioned to the QS running job it’s best to leave any ring final circuits off so fly leads can be disconnected to get a true reading of the circuit.
I’ve now come back to everything screwed back, painted and basically signed off, so they don’t want any sockets taking off. I’m getting far to low r2 reading (r1, 0.49, rN 0.49, r2 0.17). And basically been told to write down the results that I get and that’s it.
So now I’m posting on here to get some advice, is it acceptable to write down these results I got? In my opinion I’ve not really proven the integrity of the circuit, could be disconnected and touching a back box for all I know, and can you still carry out the formula to see what sort of R1+R2 readings i should get with these results (r1+r2/4)?
