Help with EICR code

[tom79bmth]

Just doing a EICR report

On the upstairs lighting circuit for some reason they have taken two 1mm t&e up both cables are fine for IR and r1 + r2 both on a the same 6 amp mcb

I cant see it 2 be dangerous does this need a code ?

 

[telectrix]

are these just 2 parallel cables, or do they split to 2 sets of lights?

 

[tom79bmth]

they split to sets of lights bit like a ring main

 

[telectrix]

but do they form a ring, or 2 radials into 1 MCB?

 

[tom79bmth]

No they form a ring in 1 mcb

 

[telectrix]

then it's no problem. although unconventional, there's nothing wrong with it. just get the r1, r2, and rN ( end/end) resistances as well as your R1+R2 for the circuit.

 

[tom79bmth]

And fill the certificate out like it's a ringmain

Thanks for your help

 

[telectrix]

ring final, not ring main. :hurray:

 

[oldtimer]

Hold on just because 2 lighting circuits are on the same MCB does not mean they are wired in the form of a ring but of course you would know that because you checked between them right ? or you suspect its a ring which one then

 

[tom79bmth]

Really !!!!!

 

[telectrix]

what OT means is-- have you established that it's a ring by measuring end to end resistances o all 3 conductors.

Of course I have, I am not going to look at it say that's a ring it's got 2 cables in mcb.

Anyway thanks for help telectrix, I haven't given it a code, just made a note of it on EICR

 

[telectrix]

That's fine then.
