New construction preparation for future experiences

The cable installation shouldn't be that expensive, maybe you can even do it yourself and have it connected later when the time comes.

Hi,

Pulling that cable shouldn't be that expensive; maybe you can even do it yourself and then have it connected later when the time comes.

Unfortunately, such a 400 V line costs a bit more if it is done properly. It should be the "large version," so 32 A and then all phases individually fused. That quickly adds up to 300-400 euros. Later, it will certainly be more expensive...

Best regards,

Andreas

Just install the empty conduit. That saves a lot, especially when the solar installer can then supply everything from one source.

Just include 2 empty conduits. However, I would rather not use 20mm ones, but go straight for 32mm. Especially with thick and rigid cables, it will be much easier for you later on.

Thank you for the response, then I will initially restrict myself to empty conduits.

On Friday, the electricians finished the rough installation at our place, and I just noticed that I forgot to have the empty conduits for the photovoltaic system installed, even though they were on my list. Since the drywall boards on the upper floor are coming next week, there is not much time left. Do you mean the corrugated flexible conduits or the rigid empty conduits by the empty conduit? I was just at the construction site, and the rigid conduits are definitely not easy to install because of the sloping roof. Can I simply install ribbed flexible conduits, or is that not sufficient? Thanks
