Temporary power box 100/120m away from the power feed point

Hello,
I have a question regarding the construction power box, whether anyone has experience with how the box may be set up. The white power box from the utility company, where the construction power distributors are usually connected, is about 100m away. Now my question is how far the distributor may be set up from the feed-in point. The background of the question is the experience at my brother's construction site two years ago, where the distributor was connected directly next to the feed-in point and it always required laying about 80/90 m of cable. At 230V that is still manageable, though annoying, but with the 380V cable with a 30mm cross-section, it is no fun anymore. Ideally, the box would be located directly in front of the construction site. The only question is whether that can be realized.

Isn't that the concern of the licensed electrician or utility company??

But somehow also mine because I am already thinking about it. Just wanted to listen in to see if maybe someone has experience with it.

Well, anyway, you will have to rent the box from an electrician and he will bring everything necessary...however, it will not be cheap because of the distance...

I assume that it will be more expensive; having the cable in place is also a risk. However, if I calculate the time saved, and I know from experience that it takes a lot of time, the effort is worth it.

I assume it will be more expensive; it is also a risk to have the cable lying around. But if I calculate the time saved, and I know from experience that it takes a lot of time, the effort is worth it.

Why don't you apply for an early house connection? You will need it anyway
