ᐅ Electrical Planning On Site: Tips and Warnings

Dear forum community,

The electrical subcontractor from my general contractor has now reached out, saying he would like to finally discuss the electrical planning on site (at the construction site). I know that normally it is recommended to plan this trade from the very beginning, but that was not possible with my general contractor and the subcontractor; they explicitly wanted to do it only once the shell is finished.

Now, I would like to tap into the forum’s knowledge and your experience for general tips regarding electrical planning.
First, the standard equipment from my general contractor:
[QUOTE=Scope of work from the general contractor]
You will receive the complete electrical installation according to VDE standards including
meter cabinet, distribution panel, equipotential bonding, circuit breakers, and residual-current devices in the building.
Standard switch program and sockets (Elso, Berker, Jung or Busch/Jaeger) — white. Connected load of the
house: 14.5 kW. Battery-powered smoke detectors will be installed in all required rooms.
For underfloor heating, all rooms will have room temperature sensors. CAT 7 network cabling consisting
of one RJ45 double socket in the living and bedrooms and a patch panel in the utility room.

Hallway
1 lighting point
1 two-way switch
1 double socket outlet
1 doorbell system with chime in the hallway
1 external lighting point

House connection room
1 lighting point
1 off switch
1 double socket outlet
1 connection for outdoor temperature sensor
1 socket for the washing machine

Kitchen
1 lighting point
1 off switch
4 double socket outlets
1 socket for the refrigerator
1 socket for the dishwasher
1 cooker connection outlet
1 socket for the extractor hood

Living room
2 lighting points
2 two-way switches
4 double socket outlets
1 antenna empty conduit
1 telephone empty conduit
1 lighting point for the terrace

Guest WC
1 lighting point
1 off switch
1 double socket outlet

Each additional room
1 lighting point
1 off switch
3 double socket outlets

Bathroom
2 lighting points
2 off switches
4 socket outlets
[/QUOTE]

Furthermore, it is clear from my side that I need deep flush-mounted boxes for the blinds and shutters. I plan to equip these with Shellys for centralized control (probably at a later stage).

Other thoughts we have already considered:
- We do not want spotlights
- If in doubt, rather one double socket outlet and a power strip than banks of quadruple outlets
- We have already purchased square and rectangular LED panels (a total of 7) which will provide basic lighting, but we have absolutely no idea about specialized lighting concepts. Indirect lighting is already a familiar term.
- We cannot afford professional lighting consultation.
- I am interested in automatic lighting control with motion/presence sensors. Is this easily retrofit-able in a conventional electrical installation? Can such systems be time-controlled? For example, in the hallway, the light turns on via motion sensor, but after 10 p.m. (22:00) only dimmed and after midnight (0:00) not at all? Additionally, overridable by a switch?
- My wife likes cold, very bright light, while I prefer cozy, warm light. The aforementioned LED panels are adjustable. Are there alternative options for this?

From your perspective, what are the most important things to consider? What practical solutions have you implemented beyond the standard equipment that you would not want to miss?

Anyone is welcome to make concrete proposals. My floor plans can be found here (please ignore the furniture shown):

Thanks and best regards,

I would plan enough network ports where it is already clear that many devices with network connections will be installed, to avoid having multiple switches in the room. At first glance, this would apply to the living room TV area and also the office.

In the open-plan living area, we had two TV positions installed; one is now located behind the cabinet.
Remember the speaker cables—we installed them ourselves using 4mm2 (11 AWG) wire.

On this topic, I increasingly realize that I’m out of the race, which actually gives me some peace of mind.
In our current, really spacious apartment, we had network outlets installed everywhere before moving in; the electrician was very enthusiastic and wanted to set everything up optimally.
Today, after almost 2 years, I have never used a single one of those outlets. My fancy laptop doesn’t even have a LAN port, and I still can’t imagine why I—or rather not “someone else”—would ever need one. I’m not sitting here doing nothing, either.
Netflix, Spotify, Bose speakers, and whatever else—also when I have young guests over—everything runs over my ordinary Wi-Fi with a simple Fritzbox router, and I’m glad that at least in this area, my new build will cost less than most of my building colleagues here.
Getting older can sometimes be quite reassuring.

Everything works perfectly, and when the kids take over the TV and sound system with their phones, grinning from ear to ear, it’s lively and noisy here—anything from Paw Patrol to hard rock.
All devices are connected via LAN/Wi-Fi, which is more than enough nowadays.

hm well, when I copy larger amounts of data, I prefer using a cable right from the start 🙂

But that probably only applies to certain Danish western suits….. 😎
As I said, I can only speak for our situation here, and in my house people are still working with current online activities and much more. It’s not a criticism, I’m just happy that, based on long experience, I simply don’t need it, even though I use everything that Apass offers me.
