Hello everyone,
We are in the process of building our single-family house and have had an initial meeting with the electrician to discuss the first planning phase. He will be laying underground cables in the garden, and the quote specifies 5x1.5mm² (5x16 AWG).
I assume the cable looks like this:
- Yellow/green
- Blue
- Black
- Brown
- Gray
I will install outdoor sockets in the garden and plan to connect yellow/green, blue, and black as usual.
What are the other two wires for? I believe they might be for a separate circuit, but why?
I have a second meeting next week and will ask directly, but I want to be at least somewhat prepared.
Thank you
Best regards
Marco

In gardens, the cable runs are often quite long, which causes significant resistance. If you plan to connect high-power devices (such as lawn mowers, heat lamps, etc.) at the end, you will quickly need significantly larger cable cross-sections.
So, think again about what devices you want to operate from the outlets.

Later on, you might want to control a light with a switch or a pond pump or something else.Thinking further about this: It might be worth making one of the phases switchable with a switch, for example, to control garden lights.
For the area directly around the house, we used 5x1.5 cables; two of the phases are switchable. We have currently used the first for lights in the corners of the terrace, while the other phase is available at various points along the property boundary in case we want to add lighting there.

I already have basic knowledge, but this will be the first time I’m working with 5x1.5mm² (5x15 AWG) cable 🙂Sorry, but in some areas, illusion and overconfidence are dangerous, even for others. Anyone asking whether the neutral conductor and grounding need to be connected in other circuits clearly has no basic knowledge.
How on earth can you have a circuit without a neutral conductor at all?!
Please, no experiments. This is life-threatening.

I know that yellow/green and blue need to be connected, but the question was different. 🙂MarcoGT schrieb:

But what about the yellow/green and blue if I want to use black and gray; will they then be connected to all three phases?Those were the two questions, right? And weren’t they answered competently? 😉opalau schrieb:
Expanding on that idea: It might be worth making one of the phases switchable, for example to control garden lights.
For the area directly around the house, we used 5x1.5mm² (5x1.5mm²), with two of the phases switchable. We have now used the first for lights in the corners of the terrace, and the other phase is routed to various points along the property boundary in case we want to add lighting there.Only low-voltage lighting (Philips Hue) is connected to this cable, nothing else.
There are additional sockets on the terrace.
Good luck
