He merely said that the fuse was still intact, from which I inferred that it must have been the correct 0.85mm diameter wire - otherwise, he would have said so, wouldn't he?
Not necessarily.

Particularly if he doesn't have, or hasn't yet used, a micrometer, or if his eyes aren't good enough to detect a difference of 400 microns.


50 Amp water heater...... (some water heater that must be!).
I wonder if it's this one.

BAS, you're right - that's exactly what it was. A Powerstream 12kW. The customer said that it wasn't really that good and that it took ages to fill the sink with hot water. Not surprising, if you consider the voltage drop!

Forget the micrometer, BAS. That's just silly.

Any electrician worth his salt, would easily be able to recognise a 30A fuse element - just by sight alone, whether he wears spectacles or not.

The fact remains that this "electrician" has said that the fuse element was still intact. He has given no hint of an over-sized fuse element. Therefore that damage can only be due to a loose connection.

If you seriously wish to discuss 'microns', then you are simply splitting hairs. Do you really think that fuse wire sizes are available in such small increments? Are you suggesting that the O/P's customer has repeatedly "rewired the 30A fuse with 60A wire? If so, why didn't the O/P "electrician (?) spot that - and why didn't the 2.5mm cable suffer as a result?

Don't trouble yourself with an answer, dear.....

I already know the cause of this damage and I suspect that the O/P is inclined to exaggerate - I just can't think why he would......

It would seem to me to be the most reliable way for someone without bionic eyes to distinguish between two wires different in diameter by 0.4mm.

And would just as easily recognise a 45A one, even if he'd never encountered one before?

Or an oversized fuse element that he's not yet detected?

I believe that if you put the right glasses on you'll see that the figure I mentioned was 400 microns, which does in fact happen to be the difference in diameter between 30A and 45A fuse wire.


Are you suggesting that the O/P's customer has repeatedly "rewired the 30A fuse with 60A wire?
No.

Why do you think that's what I was suggesting?


If so, why didn't the O/P "electrician (?) spot that
Spot what? A fuse wire 0.4mm bigger than it should be? IF that is there to spot then maybe it's because he doesn't have, or hasn't yet used, a micrometer, or his eyes aren't good enough to detect a difference of 400 microns.


-and why didn't the 2.5mm cable suffer as a result?
Do we know it hasn't?


Don't trouble yourself with an answer, dear.....
Why not?

Nor I.

But despite his denial of exaggeration, and despite your inability to think of a reason why he would exaggerate, you still think it's OK to make the accusation.

Why is that, I wonder?

Oh well. at least we're agreed that the O/P is in need of a magnifying glass, a micrometer or a little more experience in the nature of such localised damage to a fuseboard..........

Carry on defending the indfensible if you must, BAS. It won't change my opinion of you, dear.......

It seems that the O/P still has "The components of the fuseboard in his gagage" - perhaps as a souvenir? - God knows why an experienced electrician would hang on to such trash......

However, he is now going to inspect the fuse link - at last!


God! give me strength to carry on in this sad industry.......

It actually shows that no matter how many rules and regulations you have you cannot eliminate:

1. Those who know nothing of the regulations.

2. Those who dont give a **** about the regulations

More regulation WOULD NOT stop this.

More education might!

Lucia. I suggest you go and dig out your copy of Technical Ecstasy and chill out a bit.

I wonder why I have a box of fusebox components in my garage... ? Maybe it's because I am not inclined to leave rubbish at the customers' houses when I've finished a job. Does this make me inexperienced? I suppose you would just throw it in the bin.

Anyway, if you actually read my previous comments, you will notice that I have already looked at the fuselink, so no need to be surprised that I hadn't done so already. It looked like 30A fusewire. I do not have bionic eyes or Vernier calipers.

Also, if you read my previous comments, you will notice that I have denied exaggerating the size of the loads on this circuit. Yet you appear to insist I am lying. If it comes to it I will prove it to you by taking photographs. Would you like me to do this for you? If you were prepared to apologise for your comments about my honesty and professionalism, then it may be worth my while... I have to go back to the property, obviously, to undertake remedial work.

Back to the subject - The installation that the customer wired in for his workshop and kennels requires its own supply. As he only has a TT overhead supply, a new supply for the kennels may not be possible. Which means he has wasted a whole lot of time and money constructing an installation that cannot be used. Here are the options as I see them:

a) Order a separate supply for the kennels.

b) Fit a boiler in order to eliminate the water heater, shower etc. to reduce the maximum demand so that the installation can be wired into a switchfuse off the existing supply.

It looks like option a) is by far the easiest. If no supply is available, then option b) will be the only answer - and it will cost a bomb!
