Rewiring for a 10.8kW shower

You're amazing you know more about the ops property than he does, where did you get 14' from.

Frome here, maybe:

My ... then that 10 feet of horizontal travel and finally about 4 feet to the height of the back of the shower.

as you probably know, 10+4=14

Kind Regards, John.

Another smartarse.

the wire has less than a foot to reach the under floor space, then that 10 feet of horizontal travel and finally about 4 feet to the height of the back of the shower.

"a foot" + "10 feet" + "about 4 feet" = Not 14 feet

OK, if you want to be pedantic:

• "less than a foot" + "10 feet" + "about 4 feet" = less than about 15 feet

... which I really don't see as a justifiable reason for ridiculing someone who wrote about '14 feet'.

Kind Regards, John.

Because of the installation method, the 6mm cable will have a maximum rating of about 35A, so you are stuck with the 30A fuse.

It will? Is there something about the installation method I missed?

Seems you did.

Care to share your wisdom?

where did you get 14' from.

From the OP, okay 15' seeing as you're being pedantic. Where did you get 35A from?

I've highlighted in red the word "may" to signify danger. You are totally misleading the op and obviously don't know much about installation methods and derating factors.

Totally misleading? Don't think so, but thank you for highlighting the 'may' in case the OP has trouble with comprehesion. If there's something I missed about the installation method in the OP please do point it out, ta.

To the op don't be misled by this bloke, your cable is rated at a maximum 35Amps and is not suitable for a shower larger than 7kw or 40A fuse/mcb.

How do you know i'm a bloke? How do you know max CCC is 35A? If the CCC of the cable is 35A why are you suggesting the fuse/mcb should be no larger than 40A, now THAT is dangerous and misleading!

which is a 9.6kw shower due to shower power ratings being quoted at 240v.

More incorrect information.

I suggest you look at, for example, Mira or Triton specifications/instruction manuals.

However your fusebox won't be up to the job so you will need a new CU

Amazing, how did you work that out?

Ok, I assumed. But seeing as they will need an RCD and, if indeed the cable installation methods allow, a CCC of 40A, a MCB then it would seem most likely than a new CU for the shower will be required/easiest way to achieve compliance with regs.

What was the point of your post?

Er, clearly to give the OP some useful information which nobody else yet had.

Here's a thought, instead of just pointing out how (apparently) wrong I am, maybe you could tell us all how you came to those conclusions?

Another smartarse...

Correcting your smartarse stupidity is not being pedantic.

Actually the difference between 14' and less that 15' is being rather pedantic.

Why don't you stick to waffling and keep your opinions to yourself.

Why don't you?

Care to explain to us mere mortals where you found a max CCC of 35A? for 6mm 6242Y without knowing installation method?

I don't see the relationship between what I said and what you said.

Eh? Whats that got to do with it. You said the cable had a max CCC of 35A and the max fuse/MCB that could be used in 40A, which it totally wrong and a lot more 'totally misleading' than saying that a 6mm cable MAY be able to safely carry 40A safely, which is what I said.

Thanks for the suggestion, I looked up a couple and they give ratings for 240 and 230v.

Apology accepted

You have contributed inaccurracies and dangerous advice based on a desire to meddle with things you think you know about.

Apart from my assumption that a new CU will be required for the shower circuit (and I stand to be corrected) can you (or anyone?) please point out my inaccuracies and dangerous advice?

Please, feel free to quote reg numbers.

For the record here's a few choice inaccurracies (sic) from you on this thread alone:
"the 6mm cable will have a maximum rating of about 35A, so you are stuck with the 30A fuse"
"your cable is rated at a maximum 35Amps and is not suitable for a shower larged than 7kw or 40A fuse/mcb" I have highlighted the word 'larged' to demonstrate your poor spelling
"I don't waffle and I don't give opinions."

[You need to improve your reading and comprehesion skills. I said it is not suitable for a 40A fuse. Note the key word NOT.

I have to say that it's your reading skills that seem to need to be addressed....

[To the op don't be misled by this bloke, your cable is rated at a maximum 35Amps and is not suitable for a shower larged than 7kw or 40A fuse/mcb.

As you can see, you wrote that a cable rated at a maximum of 35A is not suitable for 'larged' than a 40A fuse - which is obviously not an appropriate statement (even after the typo is corrected).

This is quite incredible, to support your argument you resort to lies and altering my quoted text. I used the word "larger" and you have substituted the word "larged", there is no such proper english word as "larged".

Yes, it does seem pretty incredible - you don't seem to be able to read you own post - see 'larged' in above quote.

Do you really enjoy this playground squabbling?

Kind Regards, John

....Also I note that you have further altered what I said to to support your deceitful argument by missing out the word 'or', quite pathetic.

For goodness sake - I quoted your words verbatim - where is the deceipt? The word 'or' ('or a 7kw shower') is not relevant to my point, which is why I did not include them in my sen'tence; you should approve of that, since you are asking for precis.

Your (verbatim) words clearly are saying that a cable rated at a maximum of 35A is 'not suitable for' a fuse/MCB 'larger than 40A' - so anyone reading that would assume it to mean that it is 'suitable' for fuse/MCB which is (i.e. is not greater than) 40A - which is simply untrue, non-compliant with the regulations and potentially dangerous advice to be giving.

Kind Regards, John.
