Lay electrical wiring yourself?

The first question is can you do that and do you trust yourself to work with electricity? The second question is how long do you need for it compared to an electrician and what happens if you don’t meet the schedule and other trades then have to wait? Also, I would not take 3 x but 5 x cables.

Good morning, definitely confident, however, someone should advise and be there for support. There is a reason why people learn this profession for 3 years. And the second point I am still pondering is the concern that I might misjudge the time required (as too little). Especially with the electricity, then of course, as you say, everything comes to a halt.

a+b) you can’t say that so generally. A very common and often made mistake in electrical installation. The length of the line also has an influence. Roughly, if you go over 18m length, you have to either go to 2.5 sqmm or protect with 13A, and then you can no longer calculate 12 sockets.

Yes, that’s right, I always had the influence of line length in mind from 20m on. It should also initially serve as a rough guideline, except maybe the living room and kitchen I don’t see the need for that amount of sockets. But you are right, it has to be looked at carefully and calculated, and I am realistic enough that my knowledge as a trained car mechanic certainly is not enough. It seems there is no one here in the forum who has experience with the internet company either, so that’s out anyway.

Why absolutely the intercompany?

So if we decide to go for it, I would prefer an on-site operation. I just know that many are not open to such a project and the internet offer is at least directly aimed at the own contribution.

But it sounds too good to be true. I once played around with the kit calculator. For a standard single-family house, the following things come out.
200m NYM 3x1.5 - if you install and wire it yourself, you actually don't use 3x at all, but always 5x. Besides, 200m is far too little.
0m 5x1.5 - Interesting that they completely do without 5x. Thermostats can't be controlled that way.
25x nail clips - so you can maybe use one per slot. With your wall construction it is irrelevant, but still an amusing number.
35x sockets - I believe we have around 40-50 just in the living/dining area. Here 35 are planned for the entire house. Even the worst construction work descriptions from general contractors/developers nowadays include more.

Sure, you can certainly talk to them again, but it doesn't seem really well thought out. So you will still have to pay quite a bit extra. The 4000€ called out here with me are almost identical to the electrical installation by a professional on site.

Ask companies. The trades are still booming despite Corona. There are certainly some who can squeeze in such a one-day job somewhere.

Laying the electrical wiring yourself?
Just Google NAV 13, then the topic is basically settled.

Hello

In my house, I have laid 4,500 meters of cables (electricity, alarm system, telephone, etc.) myself. I chased all the slots myself, laid a lot under the suspended ceiling, installed empty conduits in the basement ceiling and pulled cables through them. I worked on it for 3 months after work and on weekends (not completely, I also did other things during that time). For example, in my workshop, I installed 64 sockets, one socket and one switch for three-phase current. I planned everything myself. I know better where I need what kind of electrical installations than the electrician. OK, you need a master electrician to approve it. But it saves a lot.

The NAV does not object to that, as it concerns the area between the meter and the provider.
