Wiring a 5 bedroom house

[omoeko]

Hello Everyone,

I am not sure of the etiquette here on the forum, but I would like to start by extending warm greetings to everyone in the house. This forum is very useful for me and I have learnt a lot from it.

I would like to ask a question, its about the list of materials required to wire a 5 bed house. I have the list below, and would like to know if its correct etc.

3/4 double sockets per bedroom, and everywhere will have spot lights apart from the bedrooms. I also plan to use a double electric oven, which is rated at 4,400W and hence a 6mm cable needs to be used. The distance is about 10m from the board to the kitchen. Below are the oven specification.

Energy efficiency class (2010/30/EC) - cavity 2 : A Energy consumption per cycle forced air convection - cavity 2 (2010/30/EC) : 0.80 Energy efficiency index (2010/30/EC) : 112.9 Energy efficiency index cavity 2 (2010/30/EC) : 94.1 Electrical connection rating (W) : 4400 Current (A) : 20 Voltage (V) : 240 Frequency (Hz) : 50

Are you a Qualified electrician ?
are you registered with a trade body for Part P ?

As of 1 January 2005 it is a legal requirement for all work on fixed electrical installations in dwellings and associated buildings to comply with relevant standards. The relevant UK standard is BS 7671:2008, 'Requirements for electrical installations' (The IEE Wiring Regulations 17th Edition). BS 7671 covers requirements for design, installation, inspection, testing, verification and certification.

Best you ask for a reputable Suitably qualifed and registered contractor to carry out the installation for you, and then to provide you with the relevant certification and registration to the Local Authority

or risk electrocuting yourself or a massive fine or both

Is this for DIY or for a paying customer?

 

[omoeko]

I am not doing the work myself, as i am not an electrician. Just want to ensure that the list of materials is somewhat correct, as i supply the materials to the sparkie.

Then you would be best checking the list of materials with the person carrying out the work so they can check it is suitable.

you are on your own matey....... this forum isn't going to give you a detailed list so you can supply cheap and nasty products to some unsuspecting sparks.

 

[Jurassic Sparks]

Or try to get them cheaper elsewhere !
I make a small profit on my materials, I will even let you in to a secret
its 20 percent
that covers my time, my knowledge, and the fact that I often forget something, and have to pay for it myself

if you take your expensive German car in for a service, do you purchase the oil and filters, plugs, brake pads as cheaply as you can ?

Dont be so negative and quick to judge, i was given a list of materials by my sparkie and I thought it would be good to have it checked by someone else to ensure its correct etc.

Without seeing the job we cannot know if it is correct. That is for you and your electrician to work out.
If they have produced the list for you why are you asking about it on here ? Don't you trust the electrician ?

 

[omoeko]

Just double checking.

Thats all.

[Jurassic Sparks]

It is not negative, you do realise that the Law changed a few years ago, Corporate Manslaughter can be used to Imprison a person who kills through poor workmanship/shoddy materials, unskilled labour

if the Electrician has missed something off ( it happens) then you will have to pay for it later

You have a contract with a Sparkie, even a verbal contract is a contract in law
if he gets it wrong argue it with him
or do you think he is trying to make a few quid by getting you to provide extra materials ?
Hows that Nice German Car ? an AUDI is it ?

 

[Octopus]

Dont be so negative and quick to judge, i was given a list of materials by my sparkie and I thought it would be good to have it checked by someone else to ensure its correct etc.

If that list was created by a spark then he or she isn't a very good one...

Do you have ANY idea of the knowledge of the parts and time it takes to get this all right?

Whenever somebody tries to do this to me I simply point out that for every minute/hour wasted by the parts being wrong/ not available will be changed at my normal rate.................... and I won't warranty anything that the client has supplied.....

So no, not being negative. Simply realistic.

My Motor Engineer ( he is a Proper motor engineer) had a chap in with a Skoda Octavia Diesel Estate identical to mine
Cam belt change was due, John quoted for normal service, plus cam belt, idler pulleys, tensioner, water pump, and Aux belt, plus some bolts that need replacing at the same time
Chap decided that John Knew nothing, and bought a cam belt off ebay
got a mate to fit it ( who is a mechanic, well works at quick fit)
4 weeks later spanking up the M way on Holiday
water pump seizes, strips belt
pistons hit valves, massive bang
the car had only done 35K and is now worth 100 quid for scrap
my Octavia that was always serviced using the correct parts, recently passed 200K in the hands of its new owner
I never bothers asking him what parts were needed or how much they cost
just left him to it
some people know the price of everything and the value of nothing

Don't think he would be happy with the single core cable you want to supply him with, or the 2.5 3 core and earth come to that

He won't be happy with that arrangement either.

Should be an interesting afternoon

Why's that Murdoch? you reckon it's a windup?

 

[DPG]

What an odd thread. Can't believe the sparky needs supplying with the 25mm open grommets - presumably he keeps these as a fairly standard bit of stock??

Of course he isn't is he?

Hi omoeko. Welcome to the forum.
No one is being negative, (as Murdoch said) just realistic.
Why isn't the electrician getting the parts?

No your list the one your Electrician has given you is sadly not a list that a professional Electrician would have provided:
You said in your original post that the cooker is some 10M from the CU (fuseboard) and has specified 10M of cable, that statement alone is confusing, the distance may be 10M but by the time the Electrician had navigated corners obstacles he will undoubtedly find whilst running that circuit would be more like 15M or 16M in length, single cables? whats all that about? 25mm grommets 2.5 3core, shower shaver sockets, all smack (and I'm sorry to be so blunt) of someone who knows little if anything of wiring a domestic dwelling, it's plain to see that the amount of cable someone has specified is not only the wrong sort of cable, but the amount is know where near the amount needed for a 5 bedroom house. This Sparky you talk of where does he come from? because he certainly sounds like knows nothing. nd I'm not being negative, just truthful.

 

[omoeko]

Why is that ?
They come from a well known electrical distributor.

Don't think he would be happy with the single core cable you want to supply him with, or the 2.5 3 core and earth come to that

 

[omoeko]

This is what he told me, he measured it and said 10m of cabling to the CU. Excuse my language.

The shaver sockets are things that i have put in so I do not forget.

What cables are the wrong type here ? I have only asked for spot lights, and I dont know if he has made a mistake.

What type of consumer unit are you going to use out of interest?

 

[Pete999]

Why is that ?
They come from a well known electrical distributor.

Where do I start? the single cable you talk of, unless it's insulated AND sheathed, it would be of little use to you unless you intended to run the cables in a continuous conduit system, the 3 core and earth 2.5mm2 you also speak of what is the intended use for that? The SWA as well, is the Garage remote from the 5 bed roomed house? the Fuse board no mention of RCDs, bonding?what size? green earthing what's that? I could go on, but unless you bite the bullet and get a proper professional quotation, you will be wasting 1000s of pounds cash as well as your time. Without any wish to rain on your parade, you clearly have very little idea of what you are doing, or intend doing. Sorry to be so blunt but thats how I see it.

 

[omoeko]

He said a 12 or 15 way would work, if using a 15 way some would be blank according to the notes that i took.

What type of consumer unit are you going to use out of interest?

 

[omoeko]

From my notes
Its a conduit system buried into the walls using a channel or something like that.

I thought the 3 core and earth is used for multiple switches ? Not sure.

Also, the 3 core cables isn't that the one used for double sockets etc ? I feel this is the one that someone previously stated is not enough.
