Hello!

What capacity and cable cross-section are you installing in your garage? My utility provider normally supplies 63A and 30kW capacity for the house. Each additional kW costs 95 (net).

Since in a few years there will probably be two electric cars added, this needs to be planned for. Currently, I’m undecided between 11kW or 22kW per wallbox. In the second case, the total 30kW capacity obviously wouldn’t be sufficient.
The cable cross-section will likely be NYY 5x16mm² (5x0.63 inch²).

What have you planned or implemented?

We have 16A and 32A outlets in the garage. That should be more than enough. Although I’m not planning to have an electric car in the house anytime soon. I’m not interested in emotionless lithium batteries that are produced under harsh conditions involving child labor. My health is important to me as well, and I’m not into conspiracy theories.

You should read fewer myths. Just take a look at how dirty the oil industry is. But that’s not the topic here.

I had a connection pedestal installed at the edge, in the middle of the property, next to the driveway.

If something related to an electric car comes up eventually, a cable from the pedestal to the charging box with a separate meter will be enough. Until then, a CEE 32 socket in the carport meets my needs.

But if I were you, since you will probably want one or even two electric cars sooner or later, I would also lean towards getting a charging box. In my opinion, you don’t really need two.
