Temporary power distributor - buy or rent?

Yes, it can be.

In the meantime, I have already bought a used construction power box myself. I still need the cables.

And? How much did you pay? Not every electrician has the authorization to connect this part. You really have to make an effort and make inquiries locally. It may be that you are paying extra now. After all, the calculations are mixed calculations; if I remember correctly, the rental was still the least expensive.

300€ for the construction site power box, versus 111€/month for the rent. Of course, I now have to make an effort to coordinate the installations. And not every electrician can do it. Yes, calculations are often mixed calculations and and and.... Of course, we plan to sell the construction site power box again in the end. Speaking of which... the connection point is already there on the construction site.

Connection point is already there on the building plot.

Otherwise, it would not be developed either. Find out and then report back

With us, the executing electrician brought the box, connected it in December, disconnected it the following July, and took it with him.

Price: 0.00 Euro (was included in his calculation for the other work)

Hello, construction power and construction power box are the same, I believe. No, construction power is applied for from the energy supplier, but not the construction power box.

I wrote something completely different, you just had to read properly. ...
