Prepare garden lighting and electricity

Hello everyone,

for us, besides irrigation, the topic of electrical work and lighting in the garden is also currently important. The lighting on the house itself, outside, has already been planned. We are quite well positioned there. Therefore, we do not want to overdo it in the rest of the garden. Nevertheless, we want to keep the option open to use additional accent lights. For example, in the flower beds or on standard trees and shrubs. Currently, we still have about 50 cm to build up. Therefore, it makes sense to lay the empty conduits in the ground now. However, these are not finalized yet. Nevertheless, I should soon establish the basic structure so that we have power at the possible points. How is this best planned, how do the cables branch out, where must the endpoints be, and especially in what form so that I remain flexible and can work later? Our electrician is a good man but rather pragmatic and not the best for discussing something like this in advance in detail.

To avoid unnecessary effort, I would at least like to lay the empty conduits and set the junction boxes. He should then check and complete the connection.

We have a cable in front of the house with a 13 mm cross-section and 5 cores as well as a cable behind the house with a 10 mm cross-section and 3 cores. The latter should be used exclusively for 3-6 LED lamps in the garden that can also be switched together. The cable in front of the house should be branched off directly in front of the house so that power is available for a yard gate. But that is just the preparation. Otherwise, it should go over an empty conduit more than 50 m to the back and supply the pool technology separately. Power consumption when everything runs together according to the pool builder is 3.2 kW. Is all this generally okay? Do you have some pages you can recommend to at least estimate whether the power over the distance is possible, etc.? Or how the branching points or the endpoints for the later consumers should best look?

For the lighting, I wouldn't lay any empty conduits at all. Just google "lightpro". You only need to lay a 12V cable through the garden and can attach a lamp at any point on the cable. No sockets necessary and infinitely expandable. You only need a socket for the transformer in one place. We have this in our garden and are very satisfied with it.

I don't really have an answer to the questions but I have electricity in various places in the garden including

[*]cistern pump [*]lawn mower robot [*]Christmas tree lighting [*]hut electricity [*]electricity for the children's house lighting [*]etc.

Many things here are also switchable and water-protected, quite nice :)

The low voltage system certainly has its appeal. But I want to be able to control the lamps at least also via KNX. That is now how all our other outdoor lamps are programmed, and it is really convenient.

Now I have to ask again, since my garden landscaper is also convinced of it. Can the cable at least be somehow concealed? Or does it always have to lie on the surface?

You can lay the cable in the ground. We have stone beds in the garden and here it simply lies under the stones. You can't see it at all.
