Eicr

[cliffed]

Does the cable have to be replaced? Is it underrated for its current use?
If its unsafe (can't see how it is if its on a 32A RCBO) then yes it has be replaced.

No the cable does not need to be replaced,4.0mm cabling is rated at the lowest 32 amps in the regs table.
It's just another persons interpretation of the regs,I don't agree,thinking of the client here too.Complete waste of energy,when everything is ok.
Thanks for all replies,so many different opinions

As Lee says what are the installation methods for these cables, doing an EICR it is hard to judge unless you can see the full run of the cable. I find it difficult to believe, although not impossible these cables would actually comply. Bet the op would rewire them if it were a straightforward task, no questions asked.

Maybe,but there is no tell tale signs of damage to the cabling,it's definitely sheathed,I certainly won't be changing it,but maybe somebody else might,its down to my gaffer to decide.

So you decide to call them idiots because you feel they have used incorrect judgement, well I agree with them.

Yes I do call them idiots,complete bulls...

Cable size Rating in Amps
1mm 15
1.5mm 19.5
2.5mm 27
4mm 36
Rating of t/e cabling

I think a closer look at the oven instructions is called for. It could be that it has an oven and a grill and you can't use both at the same time..... which could have huge implications on the diversity calculations.

Just saying.

We have a range master cooker, which has a "theoretical" load of 17.7Kw - the manufacturers ask for 6mm cable and a 32A breaker...... I installed 10mm and a 40A breaker as it was part of a rewire....

Yes those ratings are for clipped direct or for a cable in masonry with no mechanical protection. If the cable is contained in oval conduit then the rating is greatly reduced. But I suspect you are not really interested in alternative opinions.

Pls reply cliffed to confirm the situation.

Then I am confused about these




@cliffed Clarification pleeeeeeze!

 

[westward10]

I can only assume the op is poorly worded and it is actually two circuits, but who knows.

 

[Wilko]

Hi - from afar it's hard to say definitively - but 4mm probably best protected by 20A mcb, unless the circuit can be visually confirmed as being clipped direct the whole way (as other folks have said )

Sorry,2 cables installed,these are 4.0mm t/e,one for each cooker

Agree also on this, shouldn't think cookers would be over this when being used.

Call me an old traditionalist, but in general terms I would install a 6mm for a cooker circuit (i.e. 32a supply) & 10mm for a shower circuit (40a supply) in the absence of any known appliance. Otherwise, the home owner may have to rewire that circuit ever time they get a new cooker or shower, or when there's a change of ownership.

That said, my really expensive Hotpoint Range cooker , has 1.00mm flex (manufactures). So I could probably run that off the lighting circuit. I'd better go turn it on now, to warm it up for the roast dinner!

Quite right, don't know where this 30 years ago it was okay business comes from. I have never put in a 4.0 cooker supply.

I have, plenty of times. Obviously it's reference method dependant though.
