Electrical installation material, where to buy

Hello Forum,

Has anybody experience of purcahsing electrical installation material. And from where ?

I'm talking about the basic stuff (not the current-carrying components), such as KRF/KRH flexible conduits and accessories, 'UP abzweigedosen', and so on.

It is possible to buy it at Baumarkt, Jumbo, etc, but the prices are high. Basically the 'elektro gross handlers' such as Steffen, EM, etc, will not deal with private sales, only to companies. Would be nice if I could buy the majority (I know precisely what I want) at a good price, with Jumbo/Baumarkt as backup for minor items. (I know a friend who bought a portable 3-phase distribution block from Steffen in Spreitenbach, but it was a very difficult purchase requiring a lot of convincing that he knew what he was talking about before they capitulated and finally sold it to him.)

(It's also pointless asking my Swiss colleagues, as they just jump around like a pea on a drum, shouting the "ohh, you cannot do that, it is forbidden." mantra, which I am honestly getting a bit tired of.)

Cheers !
Chris

Re: Electrical installation material, where to buy

Just to follow up, I found an electrician who is the neighbour of a friend. I created a list and he ordered it from the wholesalers. Interesting to see the trade price as we were putting the order together in his office; some items were much cheaper than what you see in Bauhaus/Coop/etc - other things were pretty much the same price. Examples (after adding his margin) - M25 flexible conduit - half price. Combined RCD/MCB, 16A, 30mA (Hager) - same price as Coop. 1.5mm˛ installation cables - same price as Coop. Switches and sockets - half price.

A lot of people claim that Coop/Bauhaus only sell cheap rubbish (as is very often seen on www.haus-forum.ch) - codswallop. I wouldn't call Feller, ABB or Hager cheap rubbish by any stretch of the imagination..

Cheers, Chris

Coop Bau & Hobby stock quite a wide range of stuff, conduits, terminators various different cable sizes and lengths, I think I saw trips and distribution boxes in there as well.

Alternatively the big Ottos do similar. I am pretty sure they had the 3 phase lagrange terminators as well

As long as you do not touch the main distribution panel and the circuits you are working on are all protected with a RCD (FI-Schalter) it is perfectely o.k. and legal.
The relevant law is the NIV especially Art. 16 Abs. 2. You have to document the installation and show that it is safe Art. 5 which may need a safty inspection when all work is done.

PS: Why don't you order your stuff to your work address?

Yep, all of that I know very well; along with all the standards behind (I am an electrical engineer and work with a lot of these standards anyway). Generally how well people comply with it, I don't really know. It sometimes seems a little disjointed that some things are strictly forbidden by law - and others not. I can, for example, completey rebuild the braking system on my car and then go shooting off down the motorway at 120 km/h. Irresponsible, yes, but there is no legal requirement for testing and neither that you must have the work done by a competent person.

On the other hand, imposing such restrictions can be more about maintaining the service industry itself, with the restrictions being, for the most part, sold in the name of safety. In the UK, since the introduction of Part P (for electrical work) in 2005, the industry has done very well indeed, thank you.

But the difference between CH and UK is that here, everything is absolutely explicit, black and white. In the UK, it's often open to interpretation. An example of this is doing gas work - do this in your own home, absolutely fine. The law stopped just short of banning DIY work, as there was no evidence to support such a ban. It simply states that you must be competent to do the job in hand. But, if something did happen that was directly attributable to your DIY gas installation, you could be in trouble -- if you were a) still alive and b) found to not have the competence to do the job in hand. Which is the same process as if you incompetently built a garden wall that subsequently collapses and seriously injures a small child. Both could see you prosecuted.

Same issue with 'Part P' electrical work; most people think that you must have an electrican to do the installation, verification and notification. No, this is not defined. So long as you can do the work to the required standard, do the verification and show that your work complies with the standards in place - you can do it all yourself.

Neither system (UK or CH) is perfect. It's frustrating, though, when you are perfectly capable of completing a job, but someone else has decided that you are not allowed.

Sorry, I've drifted a bit:
