ᐅ Outdoor Electrical Installations – Have You Considered Everything?

Hello everyone,
This week we’re starting on the outdoor area, and before laying extensive paving, I want to coordinate with the landscaper to install the electrical wiring.
Current situation: From the utility room in the basement, there is a large empty conduit for electrical wiring for the outdoor area. Currently, the following run through it:
- 1x 5x10 cable for the wallbox charger -> will be located at the carport
- 1x 5x2.5 cable for a future sauna -> runs from the carport further into the garden
- 2x power cables for the carport (5x1.5)
- 1x network cable (RJ45) -> for the wallbox and anything else requiring network connection
Everything is connected to a separate residual current device (RCD) in the electrical cabinet. At the carport, all cables currently come out of the ground, properly sealed against moisture. Here I have my first question: How do you professionally bring these cables up from the ground once the area is paved? An outdoor floor box? What do I do with cables like the sauna line that continue further into the garden? I was simply planning to continue them in a separate empty conduit into the garden.
Since it was already quite difficult to pull these cables through the empty conduit to the outside, I would prefer not to add more cables there.
My idea is to install a small sub-distribution board in the carport (there will be a garden shed at the back) and run additional lines from there to supply the other devices.
This would include:
- Another 5x2.5 cable into the garden for a possible pool and anything else like a pump, etc.
- 3x1.5 cables towards the cistern (also in the garden)
- 3x1.5 cables in front of the house under the paving heading to the inspection chamber (for a backflow valve)
- 3x1.5 cables in front of the house towards the street for a potential future doorbell at the garden gate (not planned yet but who knows)
- 3x1.5 cables into the garden for garden lighting
Since the garden won’t be done at this stage, it’s important to lay the cables under the paving now so that they emerge near our soil mound.
Are there any other important points I should consider, or have I covered everything?
Best regards

Assuming you install a 3x32A fuse beforehand, you would have 22 kW available at the sub-distribution board. Depending on the installation method, cable length, and so on, a 5x10² cable can also be protected with 40 or 50A, in which case your sub-distribution board would probably have more power available than the main supply. Please use only NYY cable outdoors, not just because of the soil, but also because NYM cable is not UV-resistant. For the conduit, I would recommend using a 100mm (4 inches) pipe, not a 10mm (0.4 inches) one, otherwise it will be too narrow 😉
Of course, only a qualified electrician should connect and commission it.

The protective conduit is just installation luxury or additional protection.After witnessing how German Fiber handles civil engineering work yesterday: I would install any cable outdoors inside 3 protective conduits if other companies work the same way. 😀

Due to its fragility, it needs special additional protection.

Fiber optic cable is quite different and not a typical cable. Due to its sensitivity, it also needs special protection.No, I meant the approach of their civil engineering companies. They actually punched a hole into the sewer pipe with a pickaxe while looking for their lost fiber optic conduit in the front yard.Similar topics
