Meter slots in the control cabinet - How many need to be there?

The price is OK, I also have the cabinet.

You then have space for 4 meters and two distribution panels in it, so roughly like this here:

Ah OK - thanks!

The longer I think about it... it doesn't make any sense anyway. We prepare all kinds of things and then stop at the control cabinet with the consideration.
I'll take another look at the old offer tonight but probably more out of interest

And when I look at all the cables that are currently already waiting to be used in the connection room... that stuff needs space too!

There is space for 4 meters, but ask your grid operator about ripple control receivers for heat pumps. Some grid operators strictly require an RSE for load shedding with heat pumps (as if it depends on the 3 kW electric power).

I then had to tear out the APZ panel and retrofit a 3-point panel because they only have RSE with 3 points. However, I was also the first EHZ customer in the area of my branch....

By the way, RSE is also available as a DIN rail version, just not from my grid operator.

Aha. Never heard of that... Thanks for the tip - I will mention it there!

In our first offer or in the price overview from the architect, I find the originally planned cabinet with two meter slots at just under 600 EUR net (if I assign it correctly). So the cabinet with 4 meter slots costs us about twice as much.
