House connection pillar in the garden vs. house connection directly in the utility room

So, I have to ask something here again. I have now ordered a HA column and already got the appointment. Does anyone know if I can now order house power instead of construction power? Of course, a distributor and meter have to be added, is it allowed to use a construction power box with meter space for that? Or do I still have to order a construction power connection despite the outdoor column. I'm asking here because the responsible contact person at Stromnetz Berlin is unfortunately on vacation. Maybe someone here knows. Thanks and regards Tolentino

Just a small addition: Someone recently told me that the fire brigade approaches the boxes in order to cut off the power to the house in the event of a fire. That is probably why the external installation/mounting is mandatory.

of course you still need a construction site power box. As long as your construction is not lockable and a meter has been installed.

Fire department approaches the boxes to cut off power to the house in case of fire.

Yes, they are allowed to and do so. However, it is not mandatory unless something has been changed again.

Yes, of course I definitely need a construction power box. The question is, do I also need to order a construction power connection? Now that I will actually have a house connection in the form of an outdoor pillar? Or can I or the electrician simply install a meter in there now and move it later? And can I order a house power tariff or do I have to order a construction power tariff? Thank you and regards Tolentino

I am in the fire department and we switch off the main circuit breaker in the fuse box in case of fire or major water damage. Only in case of fire if we find it quickly; in case of water damage, we wait if necessary until it is clearly confirmed that the building is without power.
If we do not have an electrician with us, we would never approach a fuse box located outside the building that is not clearly identifiable as the main connection. In that case, the utility company is called.

we found a connection pillar to which a house is connected. At the start of construction, we had private cables laid from the pillar to the construction site.
The electrician from the general contractor then took power from this pillar and installed the construction power box at the site. We submitted the application in advance. At the end of the construction period, the electrician disconnected the cable from the construction power box and routed it into the house; we had a 10m reserve for this. From that day on, the meter in the house ran on the normal tariff.
