To be honest, I don’t feel like digging up all the formulas to calculate this for you. It was annoying enough back in school.
Quote from VDE 0100-410 (the relevant regulation):
What is not taken into account here are the additional impedances caused by plug, screw, and terminal connections. That’s why people usually say 15 m (49 feet) to be on the safe side.
That’s how I learned it at some point….
Quote from VDE 0100-410 (the relevant regulation):
A 1.5 mm² cable is protected by a B16 circuit breaker. According to table 3, the maximum cable length is 82 m (269 feet) if the disconnection condition under the given parameters is to be met. Additionally, the voltage drop for the considered cable section must not exceed 3%, resulting in a reduced maximum cable length (2-core) of 17 m (56 feet) at 230 V. (From table 1: 34 m (112 feet), additional factor 0.5, as it is a single-phase AC circuit)

Today, the heavy retaining wall by the terrace was completed. It’s quite impressive how they maneuver such heavy granite blocks with the excavator.
After we had them remove the top row installed on Monday (it was completely uneven), they came back today with new stones, and now it fits perfectly. We’re really pleased.
In the meantime, we’ve started the smaller version of it at the back of the house; we’ll do the other half over the weekend.
One block weighs 45kg (99 pounds). I’m exhausted, and so is my back.
Tomorrow, the paver will probably start, and he also plans to work over the weekend. Next week, we’ll spread topsoil, and then that part will be done for now.

That is your garden Behind the house, there is still a 5m (16 feet) wide strip of lawn... But yes – that is our garden and our house, and that was all we could manage.
