its what i would do, match tails to the MS, not to the fuse. Fuse can be replaced for a bigger one by anyone, all kind of maintenance people have access.
you got it wrong, it was a comment only, my issue was 2 radials on one mcb, not EL on lighting circuit.
More worrying that a DI is doing commercial work ?
there any requirement to fill any gap between the cables and the edge of the qu
Thank you! what will you say about big hole behind CU to cavity wall? Cavity plasterboard on timber.subfeed 10mm 3 core swa cable to every cons unit not terminated right. Basicaly armour cut and wrapped with insulation tape... on other side is property glanded 522.8.5 c2
How do you know it's not supported correctly? It could be.
As the armour is not being used as the protective conductor as long as one end of the armour is properly glanded and earthed it's ok (but not what I would do either).
I’ll help ya out mate ??I have not even got domestic installer, doesn't mean I could not do the work, just that i can't self certify.
therefore i will stick to the easier stuff that requires no silly registration.
like 3 phase motors and controls!!
not impossible...especially that 200A MS is clearly visible! its what i learned a while ago, protect yourself from stupidity of other people.
it is no code probably, but as inexperienced in eicr im asking for advise, right?
im not trying to argue with you, and im not asking it it is ok for me to do it, i just do it, and you dont have to agree with it.So your saying that becuase the main switch is 200A someone might replace 100A fuses with 200A fuses?
If they are going to do that then how do you know they would fit 200A fuses and not 300A or 400A? Maybe you should size everything for a nice round 1000A just in case?
My point here is that trying to 'protect yourself against the stupidity of other people' is impossible and quite pointless.
If someone is going to come along in the future and replace a fuse with one of twice its rating then they aren't going to worry about what is written on any switchgear before they do it!
Sometimes I install a 20A DP switch to isolate external lights on a normal 6A lighting circuit, but I sure as he'll don't wire the whole circuit in 2.5 just because there's a switch rated at 20A in the circuit!
im not trying to argue with you, and im not asking it it is ok for me to do it, i just do it, and you dont have to agree with it.
and why would someone install 300a fuse if ON THE BOARD SAYS 200A Max.
But HEJ, even if they do im covered, as my TAILS and MS is 200A rated max! (load also matters)
And there is a difference between 20a and 100a in terms of harm it can cause, bad example.
according to esqcr and osg meter tails domestic should be at minimum 25mm2, why would that be if 60a fuse installed...maybe because fuse can easy be replaced with 100A...The same reason that they would replace a 100A fuse with anything bigger than 100A, a lack of knowledge or common sense.
Yes there is a difference between 20A and 100A, I am well aware of that, but the point is the same, the conductors need only be rated for the OCPD they are protected by not for the rating of whatever switch happens to be installed.
20A can cause a significant amount of harm, in terms of cable sizing, or more specifically incorrect cable sizing, then it can do exactly the same harm as 100A.
If Main Switch is rated lower than the fuse, then you are quite likely to have problems. Main Switch should be rated equal to or higher than the fuse, and the tails should be sized to suit the fuse.according to esqcr and osg meter tails domestic should be at minimum 25mm2, why would that be if 60a fuse installed...maybe because fuse can easy be replaced with 100A...
Im not saying that you are wrong, im just saying I would match tails to MS, unless MS rated lower that fuse. i dont think im wrong either.

@davesparks why the disagree For me when you're later criticising the op. I’m confuse?
More worrying that a DI is doing commercial work
I know a few electricians that opted for DI that do majority commercial work, only reason to get around the notification scam in the domestic sector.This is why:
I'm a DI but I do a lot of commercial and unusual/specialist work so I disagree with the suggestion that a DI shouldn't be doing commercial work.
Fair point, clearly yours and other subsequent posts show many DI's are doing commercial work and are clearly competent to carry out EICR's, but use the DI route only as a cheaper means of enabling their domestic work to be notified.That would be an incorrect statement, the NICEIC have not made an statement about his competence.
He has not paid the NICEIC the extra money to put their logo on EICR paperwork, this is not making any judgement about their competence.
However the questions in the OP do suggest a lack of knowledge to carry out EICRs, or even electrical work at all.
ah, Ok. Being in Scotland we dont have DI's but I always thought the NICEIC didnt allow commercial/3 phase work under the DI scheme. Thats where my comment was aimed. Obviously wrong.This is why:
