EFLImpudence";p="3379623 said:Are you sure?
yep
People here seem to agree with the 'europe' spec. Come to think of it, the UK is still in europe ('til Thursday at least!) so i should be safe with 1.5mm
It could be very old and refer to rewirable 15A & 20A fuses but
with 13A fuse, as above, 2.5mm² is not necessary.
I see you can use 1.5mm² in Europe with a 13A fuse which they don't have.
A valid challenge would be that it doesn't meet the mi as that cooker plate supply is likely to be fused at higher than 20a.
I guess you could argue they don't have a clue though.

That's a bit of a circular argument, because I presume EFLI was really thinking/talking about a 'valid challenge' that the manufacturer could produce to defend their instructions! As often discussed here, about the only argument they are likely to be able to produce is that something inside their product needs to be protected by an OPD no greater than 20A - but to invoke that argument would involve admitting that they had failed to include adequate internal protection in their product to make it 'safe'.

Clearly to "make it safe" you install as the installation instructions ? An OPD no greater than 20a. That would appear to be what the instructions state and that is the installers responsibility, yes?

One could say that. BS7671 now only requires that one should 'take into account' the instructions but, in the absence of any explanation as to the reason for that particular instruction, I suppose one has to assume that it may be 'necessary for safety'. However, as I said, that would only be the case if the appliance itself was 'inherently unsafe' (in the absence of external protection).
Whatever, connection via a 13A plug/socket or a 13A FCU (both permitted by the MIs) would obviously satisfy that instruction. One presumes that no-one in their right mind would go to the hassle of fitting a local OPD >13A when it's not necessary.

Would you, when using a plug, use 2.5mm² flex because that is what the instructions state?
If not, why not?
My point was to draw your attention to an unnecessary - for safety - instruction which is clearly a mistake leading to the thought that the other instructions may be doubted..
Are you saying that you advocate 'blind' adherence to manufacturers' instructions, whatever they say? I ask because I'm quite sure that you have more than enough knowledge to know that if a flex is protected by a 13A fuse, it does not need to be 2.5mm².
Kind Regards, John
Fair enough. Would you do the same if what the instructions told you to do was, in your opinion, 'unsafe'?
Kind Regards, John
I wouldn't say that - I'm just interested to hear (by implication) that you apply your expert judgement in one direction but not the other.Don't be such an a**e
Kind Regards, John
