Wiring Query

Matthew11

Hi

I have a garage at home that just has an extension lead running out to it for power.

The Garage is 30 * 18 build of cavity walls and not plastered inside.

It will be manily used electrically for powering a normal plug water treatment system. No major tools will be used in the garage so I dont need too much.

Im trying to get it wired and just need info on what might be needed for it.

Im going to run the cables and install sockets/lights/switches and get a Electrician to put in the Fuse Board and finish the wiring.

I know I need
- 4 Double Sockets with steel backs
- 2 Out door light switches
- A couple of lenghts of Conduit
- IP Rated Fuse Board
- 2 Tube Bulb lights and Fittings
- Electrical Wire

I dont know what type of wire I need and does anyone know If I would need anything else?

Thanks

Matthew

To be honest if you don't know what size or type of cable you need then the only thing you need is an electrician!!!!!!!!

hallo dare

Best left to the Professionals as advised above.

The basic domestic installations are:
Lighting: 1.5sq
Sockets: 2.5sq

Industrial:
Lighting: 2.5sq
Sockets: 4sq

There are alot of things to take into consideration when doing an installation. Let a Sparky at it, to be on the safe side

Thanks, You could be right, all I was going to do was run the cables to have something done for him.

Any other materials I would need to get for him???

Thanks

It is best not to buy materials for an electrician, you will be charged a far higher price.

Are you going to continue running this shed off the extension lead or do you intend to upgrade the supply to it? I don't believe any electrician in their right mind would take on the risks involved in this job.

CJ Haughey

The age old argument of who buys material or who gets it cheaper is not what most think.
Customer hands in quotation for pricing to a wholesalers, that wholesalers will give a very good price on the material at pretty much trade level price.
Electrician hands in his quotation to his wholesalers, gets his price for stuff. He adds his margin and comes along then and slaps 13.5% vat onto the materials.
Say customer got €500 for material quote, the electrician got similar but after adding on his margin (10%) plus 13.5% vat = €624.

If the customer cannot claim vat he will be paying an extra €124 instead of getting them himself. If he can claim vat and buys the material himself he can claim 23% vat. The 10% mark up would vary between electricians I know some who have a mark up of 20%.
Potentially the customer could get the materials for €406 ex vat by buying himself versus €550 ex vat if invoiced from contractor supplying materials.

What risks are they?

Hi, I have an cable underground going out to the garage which will go to the new fuse board in the garage so there will be no more extension lead. Just need to know if there is any other materials I might need that have not thought of??

Thanks

Do you want steel or plastic conduit?

Matthew11

was going to go plastic conduit.

CJ Haughey

You could use 40mm pvc trunking and run it around the perimeter inside the building and do 20mm conduit drops into the services.

An electrical contractor that buys hundreds of meters of a particular cable type will get it at a very different price than a DIYer will buy 30m of the same cable.

Economies of scale.

Apart from the fact that electricians know what the materials should cost, what the best materials are, what quantities to buy, they have use for excess materials etc.
Customers buying materials rarely makes sense.

As an rec myself i know first hand the way alot of wholesalers work, the margins between an electrician and a customer on quote is almost at par. Different story when a customer walks in off the street and make an instant cash purchase.
We have a €150 difference there in my example, allow for economics of scale give it €50 and that is ott customer is still saving €100.

That is certainly not my experience. I have purchased a very large quantities of materials. Perhaps you should shop around.

As per my previous post there are many other reasons why it does not make sense for the customer to buy the materials.

Its all down to economics of scale as you say, if i only buy €200,000 of material and you buy €2,000,000 sure off course your experience is different.
How much value of material do you think a single rec spends on material doing house bashing and jobs like the op has per year?

There is nothing stopping the OP or someone who uses the shed in future from plugging in various tools or appliances( both in the shed and on the circuit where the extension lead is plugged in) that may draw a lot of power. If he is confident that this won't happen then there are no risks. But probably the most likely thing that would happen is that the mcb will trip on overload so I suppose there isn't that much risk really.

Exactly that is why when the OP gets a quote to buy the materials for the job described he will get quoted a different price than either of us due to the smaller quantity.

How much value of material do you think a single rec spends on material doing house bashing and jobs like the op has per year?

How long is a piece of string?

Leaving that aside there are other reasons why it is not a good idea for the customer to supply materials. For example electricians know what the materials should cost, what the best materials are, what quantities to buy, and they can put excess materials to good use whic also means that they can accommodate changes to the customers requirements.

The bottom line is that customers buying materials rarely makes sense.

We will have to agree to disagree on this one i think, the figures are very accurate in post 7, you will also notice vat has a huge part to play, interesting link below.

I would be interested to hear your views on the other reasons that I gave for the customer not buying the materials:

It happens alot that some contractors prefer to work on a labour only basis and pass on the materials list to the customer. The customer then does the shopping and dealings with wholesalers and fights for a good quote.
The wholesalers will give them a good price and one of the reasons is they will get paid immediately for the goods, since the crash in 2007 wholesalers have got a burning to say the least from contractors who couldn't pay their account.
I would not be tarnishing all the public with the same brush, to be fair about it choosing and ordering the materials is not the same as ordering parts for an aeroplanes rolls royce engine.

Lets see then.
They both get quoted €500 for the materials excluding VAT.

The electrician adds on 10%, so that is €550 for the materials.
He then applies 13.5% VAT to the materials price.
So the total is €624.25

The customer has to pay 23% VAT on materials so the new total is €615.
A saving of €9.25 for the customer.

Or if the customer can claim back the VAT then they would save 10% which is €50. But of course the work would have to be for a VAT registered business and it would have to make financial sense for the business to spend time buying materials instead of earning money as a business.

That of course assumes that the customer gets charged exactly the same as the electrician, they buy exactly the right materials and right quantities of materials. If I were the customer I would rather pay the extra money and take advantage of the electricians expertise and experience in selecting quality materials. Each to the own I guess.

We will have to agree to disagree on this one i think

Ok.

An electrician or any business person using that logic that is in bold will not stay in business long. You add your 23% vat back on and then another 13.5% vat which would be vat on the labour too but that is irrelevant.
I addressed why its not a disaster that the customer buys the materials, your opinion is that they write up the materials list themselves, as i said alot of electricians work on labour only and gets their customer to buy materials.
There can be many reasons, one reason is if electrician don't get paid he is only out of pocket on labour, another is to keep his books down, i.e stay out of the vat bracket.

€500

He adds his margin

10% margin is €50
€500 + €50 = €550

and comes along then and slaps 13.5% vat onto the materials.

€550 + 13.5% VAT = €624.25

CJ Haughey

The 10% add on would be on top of the full price of goods which have 23% vat already in it.
Obviously then adding on labour and 13.5% vat, hence the term vat on vat.

No.
Every Registered Electrical Contractors in Ireland is VAT registered.
That means that they do not pay VAT on materials.

Let me explain: RECs are charged VAT when they buy materials, but then they claim it all back in their VAT return, so effectively they do not pay VAT on materials that they buy.

So if they want to make 10% on materials (as you suggested in post 7) then they add 10% to the cost of the cost of the materials excluding VAT.

They can then appy the lower VAT rate of 13.5% to the overall bill to the customer because the price includes labour.

That is not true, I know a few contractors who are not vat reg, who told you that? there is no single requirement for an rec to be vat reg if he stays below the vat threshold or chooses not to be vat registered at the start.

2011

CJ Haughey wrote: »

Revenue did.

While the general turnover threshold for the supply of services is €37,500, for persons supplying both goods and services where 90% or more of the turnover is derived from supplies of goods (other than of the kind referred to in the above paragraph) then the threshold for Goods applies.

If you are going to argue that a Registered Electrical Contractor is going to be below the VAT threshold then how can you explain them charging VAT?

Here is what you said in post 7:

Say customer got €500 for material quote, the electrician got similar but after adding on his margin (10%) plus 13.5% vat = €624.

CJ Haughey

Revenue state to any business person not specific an rec. If the rec is not vat reg then he would be buying the materials with 23% vat included in them and adding on his cut so effectively the customer would be still better off buying the materials. They would be both on a level playing field.
On the other hand if the customer were a farmer who could claim vat and the contractor was not vat reg the farmer would be loosing out on claiming any vat.
At the end of the day the only winner with vat is the tax man.

Correct.

However if the REC is not VAT registered then the REC can not charge VAT.
Your post 7 sates that the REC charges VAT:

Say customer got €500 for material quote, the electrician got similar but after adding on his margin (10%) plus 13.5% vat = €624.

So which is it, the REC is or is not VAT registered?

CJ Haughey

Post 7 would be a vat reg rec, my previous post would be a non vat rec.
