Carrying out an EICR and have discovered a lighting circuit has a borrowed neutral from ring main. No RCD as its old 3036 fuses but have a disagreement with my colleague who believes it should only be a C3 for improvement recommended. I was almost certain it be flagged as a C2. Anyone able to voice opinion (and who owes who a beer!)

No, C1 is immediate & present danger.
C2 is potentially dangerous.
So, C2 in this case.
C3 = improvement recommended. He can't honestly think thats just a C3 - If he thinks that's a C3 i dread to think what else he classes as a C3.
...I dread to think what he classes anything as a matter of fact, wonder how severe his C1's must be.... "i know i can see the evidence of burning, and i can smell the burning...but its not on fire yet so its not dangerous" haha.
Def C2.

I'd give this city being destroyed by tornado a C2. :-D
Well its not that serious to warrant a 1 is it ?

stop talkin like a penis will ya......
end if the day it comes down to wether the shared neutral is capable carrying the current return of any loads tied to it.....
Well yes. But, i was always taught that borrowing a neutral was a no no. Its bad practice. You'd have that as a c3 would you? honestly? Everyone medals with electrics nowadays, anyone unaware could get a belt. IMO it wants sorting + if it was my property i would want it doing properly.
I stand by what i say, and i would give it a c2.
We shall agree to disagree as i really cba to argue - the reason i deleted my last post.

go on then....
if your guns have jammed.....
you live to fight another day..just....
you won`t get away with it next time......
I deleted what i originally wrote because i cba to get into an argument online.
I just don't like the idea of borrowing a neutral from the ring main for the lighting circuit. Regardless of what the NIC say, they're muppets.
a 'borrowed neutral' is generally found in domestic lighting circuits especially the landing light. It will use the live of one circuit and the neutral of another, as as been stated, harmless to the user of the property but a hazard to sparks and wannabe sparks as someone changing a fitting further upstream on the circuit which the neutral has been borrowed from could get a belt even though the circuit appears to be off if they break the neutral.
IMO C2 any day of the week, it is a contravention of the regulations and always has been. But virtually no danger to the householder
Far more dangerous IMO is the shared neutral, 3 lighting circuits accross 3 pahses sharing 1 neutral 3 seperate mcb's. I have witnessed a sparks get thrown off his steps when he got caught out with that one!

Lol so because u don't like the idea of it means its a c2? I take it your not a member o the nic then :/

evr heard of a safe iso?...
just stop it now will ya....

Yes I know what a borrowed neutral is thank you; what I don't understand is why people are suggesting the lighting circuit would be safer if the neutral were run separately from the same board.
no the eca and elecsa....but as they've merged who knows whose registed with who anymore. i hope we're not trying to question ability here over a matter of opinion....
The way i see it is, someone incompetent could come along work on that installation and get a belt because they don't have a clue. Yes, in law you're most probably going to win, but the agro caused would be a nightmare. I'd rather have things right. None of us have seen this install anyway so we're all just guessing.

You're not there to comment on what's "good practice" or what you would or wouldn't have in your own home, you're there to comment on whether or not the installation is safe.

It's no safer its just of the same size circuit e.g 6a breakers on 1.5 cable. No damage can happen to the property, persons living there or the cable and it doesn't require immediate or urgent attention. No sparky should recieve any electric shock having completing the safe isolation procedure correctly

GLENNSPARK
THAT IS CRASS!!..... tell you what...lets just take a scam`s word for it shall we eh?
bloody hell, they cant even agree on BS7671 from one to the other....
bloody disgrace...

Someone incompetent deserves to get a shock if they believe they can safely play with electrics
alright grumpy, make sure you get out of the right side of that bed tomorrow! lol
I'll be the first to admit not testing between neutral and neutral and neutral at every light fitting i've changed.
IMO code 2
In your opinion code 3
I'm happy with that
G
GLENNSPARK
oh come on......
its neither is it.....
what you do is note it......
and move on..
and whats this `testing at every point` thing n all...where shared neutrals are concerned.....
just do it at the board....IR between em......that`l find it....if its there....

well if you only disconnect the lighting circuit your working on then safe isolation proceedures arent going to help you as you wont notice the borrowed neutral open circuit until you seperate the wiring at a connection point.
its code 2 all day long for exactly the reasons somerset gave.
314 of the regs...division of installation. Especially 314.4
Now the debate is going to be, the regs are non-stat / use common sense.
My opinion is my opinion, you're entitled to youres. Lets leave it at that, so this doesn't turn into another argument on this forum over the matter of opinion.

sorry not trying to patronise mate... just didn't read the OP properly where it said about being borrowed from a socket

Yea u read the regs that are non-stat and ill read the test certificate that explains when a code 1 and 2 should be given. But ok let's leave it as a matter of opinion
You've misunderstood me, what i mean is that I don't check for a borrowed neiutral everytime I have to change a light fitting,
As for meggering between them at the board - only if all switches are in on position and both mcb's are on in fuseboard, in fact its easy to miss by meggering

what a load of old donkey cak this is....
so you conduct an EICR.....and the next guy comes along and sees the previous report......capish...

That's the line I was thinking along.
You is too sensible sometimes to be the official troll, demotion or another ban is in order...
