Hello dear forum members,
to keep it brief: Next Monday we have the electrical planning meeting for the shell of our upcoming semi-detached house.
We have already considered the basics (location of light fixtures, switches, motors, power outlets, network sockets), but I would like to clarify a few points before I have to deal with the probably rather unmotivated electrician from the builder on Monday 🙂
Well, it turned out a bit longer than expected, sorry.
I hope you can still help me a bit so I can tell the electrician exactly what I want and not be brushed off with comments like “no, that’s not how it’s done.”
Best regards
to keep it brief: Next Monday we have the electrical planning meeting for the shell of our upcoming semi-detached house.
We have already considered the basics (location of light fixtures, switches, motors, power outlets, network sockets), but I would like to clarify a few points before I have to deal with the probably rather unmotivated electrician from the builder on Monday 🙂
- Preparation for Wallbox: We would like to have the necessary connections (11 kW, 3-phase) prepared so we can connect a wallbox charger in the future. The plan is to install the wallbox on the outer wall of the house (36cm (14 inches) aerated concrete). Will the raw cables just stick out of a hole, or how is this typically done? In case I later decide not to mount the wallbox directly on the wall but further back in the garden, could the wiring be “extended”?
- Network Access Point: Network sockets are planned in several rooms, partly single, partly double (please don’t criticize me for not having all double, I can still add more later. The number of sockets was negotiated in the contract). Some are in aerated concrete, some in drywall. In both the ground floor corridor and the upper floor corridor, I have planned network sockets to install Ubiquiti PoE access points. Since I won’t be able to embed the device in the concrete ceiling anymore, the plan is at least on the ground floor to mount it relatively high on the wall. Is there anything special to consider here, or will the connection be prepared like a “normal” network socket, and then the flat access point is just plugged in? Between the upper floor and the attic is a wooden ceiling (not built yet). Could I plan to mount it there on the ceiling, or will the electrician laugh at me and say that’s not possible?
- Network Wiring: If I understand correctly, the electrician will run the in-wall cabling inside to the sockets. These cables end somewhere, hopefully in the utility room, where they must be connected to a patch panel. Do I have to do this myself, or is this included when the builder contract states “installation of 10 network sockets”? Then from the patch panel, a patch cable goes per run into the switch, which is connected via patch cable to LAN1 of the router.
- "Smart" Roller Shutter Motors: All our roller shutters will be motorized; unfortunately, the contract does not specify which motor. We would like to control the shutters via app so we can close or open everything while sitting on the couch downstairs. What makes the most sense here? Upgrading to a “smart” motor for probably quite some extra cost? Or just smartifying the switches? I’ve also read you can simply ask the electrician to make the wall box recess a bit deeper to install a 2.5 or similar Shelly smart relay between the switch and motor if needed. Do electricians usually agree to this, or are there warranty issues? Any other suggestions?
- Power Supply for the Garden: We would like to have electricity in the garden area, for example where the shed or carport will be later. We are not 100% certain yet where exactly the shed and carport will be, so we cannot give the electrician precise information. How can this be prepared? Conduits are not flexible either.
- Intercom System: Our semi-detached house is on a great lot, about 55m (180 feet) from the street. Since the house next door is currently for sale and we don’t know what the buyers will do, there is currently no gate at the front. Surely one will be installed later; should we already have a conduit installed there? A modern video intercom at the gate probably won’t work as there will be no internet connection. Or could I have a network cable run in a conduit to the front and then connect a camera with Power over Ethernet there?
Well, it turned out a bit longer than expected, sorry.
I hope you can still help me a bit so I can tell the electrician exactly what I want and not be brushed off with comments like “no, that’s not how it’s done.”

ordered the D-Link DGS-1210-24POK, I can’t tolerate that device for long. The fans are incredibly loud. I can hear them through two closed doors. I have now ordered a rack and a passively cooled Ubiquiti USW-24-PoE-EU.
My first attempt was a failure – my wife is pretty tolerant with technology, but even she couldn’t accept this. The second try will be much better!

The second attempt looks neater!This shouldn’t be too difficult either. 😉 Joking aside: Why would you want a 24-port switch for a single 12-port patch panel? More ports → more heat → more noise.Otherwise, I think the network provider really skimped by installing only one fiber optic cable. In our area, at least two fibers per building are standard everywhere.
I definitely give a thumbs up to the dynamically angled distribution box. 😀
