Electric shower upgrade.

Thanks for all your advice,i think i better talk to an electrician.

Which is why in my post, I clearly stated He need to check, as after years in the business overseeing and running the installations of bathrooms, most showers of that rating require a 10mm cable in the average domestic installation.

So my advice is based on years of experience and a suggestion that the rating and cable size be double checked, your reply is based on what? Having your head stuck up your backside?

Overseeing and running installations of "bathrooms" does not qualify you to size cables for an unseen installation, and you DIDNT say to have the cable size checked in your post.

My qualifications are none of your business, but seeing as you asked so nicely, they include IEEE membership

The original poster made a good decision to seek the help of an electrician, I would not profess to offer any advice on an installation given the information provided whether my head was up my !!!!!! or on my shoulders ... where's yours

That's simply wrong, in fact Mira should be saying "Consult a qualified electrician" and nothing else. Which is fundamentally what you need to do, as the work will require the suitable certification now.

Oh, and assuming the poster lives where he enquired you are wrong about the certification too.

How can either of you possibly know what size cable is required.

In order to calculate the required cable size, you need information aboiut the installation, particularly the length of cable run. It could be anywhere between a couple of feet and tens of metres. If you dont know the answer then dont post, it could be dangerous !!

Raymond you seem to be confused or -

Now why don't you go back and re-read what Alan said-

Yup it will be a minimum 10mm cable, and double check the rating, I have a feeling 10.5 KW is 50 amp, or on the borderline of 50 amp.

That statement is completely true, he has not recommended a certain size cable but suggested that it will require a minimum cable thickness of 10mm.

I am familiar with the IEE and the NICEIC but what exactly is the IEEE?

I dont see a problem, he said check the rating .. referring to the FUSE rating.

What about earthing ? No information is supplied and no comment made.

What about the age and condition of the existing wiring ?

Is there an RCD fitted ?


The obvious answer in threads like this is to advise that an experienced and qualified electrician is consulted, they dont make guesses at what may or may not be required.

IEEE= Institute of Electrical and Electronic Engineers :rolleyes:

Raymond you're a jerk, I made it clear the original poster should seek professional advice, and the manufacturer supplying the advice they did is quite simply appalling.

At no point have I given wrong advice, I've given an opinion based on what all the qualified electircians have installed when I employed them to undertake installations for the business I own, thereby stopping the poster making a mistake.

Are Nothern Ireland not subject to Part P? Strange I thought that was part of the UK, or has there been a policy change I missed? Obviously if it were Eire there would be different legislation applying.

A simple post saying, "Consult an electrician would have sufficed" which I actually posted anyway.

The last two "Qualified" electricians I had on site were also from the same mould as you, and when they both arrived on site the same day spent the best part of it arguing about how each of them interpreted the part P regulations, mostly telling each other what the other was doing was wrong etc etc.....

And stating "Double check the rating" to most people with a modicum of common sense would also cover checking the cable was correct for the purpose for which it was intended to be used. As well as all the items it was connected to.....but the main thing here...is the word...check.

Sorry Raymond I did not realise that the IEEE were trained in domestic wiring!

What earthing? Are you confusing supplementary equipotential bonding with Earthing? If so I think you have your wires crossed!

AGE and condition of existing wiring? Both myself and Alan suggested that 10mm would be required and that 6mm could be inplace now!

RCD ? I suggest you read the guidelines from the IEE (Institute of electrical engineers) You will then see that a RCD is recommended but not compulsary!

Please check your facts. There are also other parts of the UK where Part P does not apply but then you would know that wouldn't you.

I don't see the point in this "argument" as you agree with what I stated anyway.

Two people said 10mm cable might do.

I said that it would require more detail to calculate the required cable size.

We all said contact an electrician so why am I a jerk ... maybe you are !!!!!! that the regulations stopped your company doing electrical installations because you didn't want to comply with the regulations pertaining to your part of the UK I dont know, I also had a look at some other misinformation given on this and other forums by people who made posts inferring they were qualified to give advice so maybe I am being pedantic.

With reference to the other poster, my question about earthing was an open one. What type of earthing is used on the posters residence, this will affect whether or not an RCD is required ... maybe you can comment on the relevance of impedance of various earthing systems as it appears you think I am not qualified to do so. Equiponential or supplimentary bonding would also come under the topic of "earthing" present/not present/ meets current regs or not/ needs to be determined. Age and condition of current wiring including fittings and controls may need updating at the same time. Did I at any time state or infer that I was qualified or trained in domestic wiring ? Did I say I wasn't ? What I am trained in is to evaluate every situation idividually, not to use design parameters meeting the requirements of some other customer I employed a contractor to evaluate.

Alan_M_2

Yup, you pretty much just confirmed my thoughts.

STOP B!TCHING, PEEPS!!!

In my opinion, the Part P regs are basically about making sure your electrics are safe - I think the OP has got the message that it would be unwise, even dangerous, for him/her to tackle this project.

As I said before, if you don't know what you are doing... DON'T DO IT YOURSELF.
