ᐅ Expand the electrical work to include low-voltage systems

Hello everyone!

For our turnkey house, we would like to expand the electrical work by EL.
As many know, the included items do not cover all our wishes.

I don’t want to interfere too much with the electrician’s work; they will also receive several additional positions from us.

However:
I plan to arrange the sockets included in the scope of work so that I can independently multiply them at the electrician’s installation site. In other words, I want to turn a single socket into a double or multiple socket. To do this, I will simply use the installed power supply line. This way, I won’t have to make major chases (channels) in the walls, but just drill the boxes and plaster them, of course. With this approach, I could save about €1,000.

What have been your experiences with EL in the electrical trade?
Regards
Käfer

Then you already know everything. So why are you still asking?

The quoted price in the BT business is quite reasonable. I know of other prices that are much higher.

If you have your own electrician, that's good, but they have to take responsibility for it. If they do it, everything works out perfectly.

The stated price is quite reasonable for the building materials business. I know of other prices that are much higher.

If you have your own electrician, that’s good, but they must take full responsibility. If they do the work, everything usually goes smoothly.

Hmm, not very helpful regarding the initial question. Hopefully, someone who has done this or something similar will chime in.

We handle all the electrical work ourselves, truly everything including the meter application. Only the meter and the main connection are done by the local utility company.

So a lot is possible when you keep the trade under your own control.

Who is building? BT/GC/CM?

The "solution" for Germany is relatively straightforward: As soon as anyone changes the electrical installation performed by the electrician hired by the general contractor / main contractor / general planner (BT/GU/GÜ) and the electrician notices, they will either thoroughly inspect every change or refuse to commission the system.

If they inspect the changes, they will of course charge for this, and the cost will probably be about the same as if they had done the work themselves. (For example, they must open every additional socket and check that it is wired correctly.)

They are responsible for ensuring that the installation is error-free and complies with professional standards. This is not a matter of warranty. So if your additional sockets cause the circuits to be overloaded (which could, for example, lead to a cable fire or building fire), they are liable. If someone is harmed (for example, from electric shock) because your additional sockets are installed incorrectly (or if their proper installation is altered during your work), they are liable. Of course, they can try to prove that they worked correctly and that you caused the fault.

If the installation is to be carried out by another licensed electrician (the neighbor?), and if that is really cheaper, then the two electricians should discuss whether the responsible electrician will accept the colleague’s work without a complete inspection. In that case, a coordinated overall plan is also necessary.

Best regards

Good evening,

I see it differently! If I install the sockets together with my neighbor, who is obviously an electrician, no one else has professional authority over it. The builder’s electrician has to take responsibility for their own work.

It doesn’t matter if you see it differently; user wadenkneifer already gave you the correct answer.

For what you are planning, there are only two solutions:

1. Have the entire electrical trade carried out by the professional electrician.
2. Extend the electrical work with your own installations only after the house has been handed over to you.

This way, you or your neighbor take the risk if any mistakes occur, not the subcontractor of your builder. I am not an electrician, but I find it hard to imagine that you can simply use the builder’s electrician’s wiring freely.

Unfortunately, this is how it is—I save quite a lot. At first, I didn’t think so. Every additional socket, no matter where (!), costs me >35€ 😡

35€ is not expensive; it’s not just the socket itself or its wiring that has to be paid for, but also the electrician’s labor and warranty. Or do you like working for free?

If you modify an electrical system (which should theoretically be inspected – keyword: report) in any way, you will lose your insurance coverage in case of a complication (such as fire, etc.).
