Electrical planning in the garden (5x1.5mm²)

You should also possibly reconsider the cable cross-section (with a professional). In the garden, you often have quite long distances, which leads to considerable resistance, and if you want to connect powerful consumers (lawn mower, heater, ...) at the end, you will quickly need significantly larger cross-sections. So think again about what you want to operate on the sockets.

Later you might want to switch a lamp via a switch or a pond pump or something else.

Thinking further: It might be worth making one of the phases switchable via a switch, to control, for example, lamps in the garden.

For the area directly at the house, we also have 5x1.5; two of the phases are switchable. We have now used the first one for lamps in the corners of the terrace, and the other phase is available in various places along the property boundary in case we want to place lights there.

I already have basic knowledge, but this will be the first time I work with 5x1.5 :) I know that G/G and blue have to be connected, but the question was different. :) Thank you Best regards Marco

Sorry, but in some areas, illusion and self-confidence are dangerous, even for others. Anyone asking whether the neutral conductor and grounding also have to be connected in other circuits has no basic knowledge. How on earth can you have a circuit at all without a neutral conductor?! Please, no experiments. This is life-threatening.

I know that G/G and blue have to be connected, but the question was different. :)

What are the other two cables for? I think to have another circuit, but why?

But what about the yellow/green-blue when I want to use black and grey; are they then connected to all 3 phases?

Those were the two questions, right? And weren’t they answered competently? ;)

Thinking further: It might be worthwhile to make one of the phases switchable via a switch, for example to control garden lights.

For the area directly at the house, we have 5x1.5, two of the phases are switched, we have now used the first for lights in the corners of the terrace, the other phase is available at various points along the property boundary in case we want to place lights there.

Only low voltage lighting (Philips Hue) and nothing else will be connected to this cable. Then on the terrace there are additional sockets.
