WilderSueden5 Dec 2020 19:59Today, I spent some time thinking about the outdoor areas and have a question regarding the electrical setup. Currently, the plan includes a garden shed, a carport/garage, and possibly an outdoor sauna if there is enough budget left. Naturally, all of this will require some electricity:
- The garden shed will house a workbench, so there definitely needs to be power for various tools. A three-phase connection for garden equipment might also be useful, although I’m a bit uncertain about that.
- The carport currently only needs a light, but since we are all expected to switch to electric vehicles soon, I would definitely plan for a high power demand there.
- The sauna is planned to be electric for convenience and to avoid chimney inspections, so it also requires a three-phase connection.
- Lights for the driveway are unnecessary because the driveway is short, and light from the carport/garage will be sufficient. The same applies for the path to the front door.
The question now is how to manage this most efficiently. One option would be to have my builder run three separate cables outside. This probably won’t be cheap since three-phase power is required everywhere. However, this would have the advantage that the garden shed’s power could be switched off from inside the house. Another idea is to only run a three-phase cable outside initially and install a sub-distribution board in the garden shed to connect everything from there. I’m unsure if this might end up being more expensive.

Also, consider internet access, for example, for internet radio in the garden shed or to check charging status from the electric vehicle charging station. Either install an outdoor access point on the house to provide Wi-Fi coverage across the entire property or have LAN cabling installed directly to those locations.
Having a few power outlets in the carport for devices like a vacuum cleaner or pressure washer is quite useful. I would recommend making these outlets switchable from a locked room.

What are the pros and cons exactly? And how complex is it to use an intermediate distribution point and a branch? I’m more of a software person, so this is definitely a hardware issue for me 😉
We’re still quite far from getting concrete quotes. First, we need to choose a construction partner. Still, I’ll bring this up in the upcoming discussions.

Hello,
I would install a separate underground cable 5x1.5mm², preferably 5x2.5mm².
Each should be protected individually in the meter cabinet.
Alongside each cable, install a sturdy 32mm (1 1/4 inch) conduit with a pull wire.
This allows you to pull in various cables later on.
And very important! Don’t forget the Ethernet cable for Wi-Fi.
Regards, Olli
