The reason high voltage and low voltage aren’t permitted to share a conduit is safety. Chafing/rub outs that would energize low voltage cable and devices with high voltage aren’t protected against in the same way that a high voltage to high voltage short would be. It’s a low likelihood/high consequence fault that every modern jurisdictions code memorializes. ------ Original Message ------

I ran Ethernet to every room, some of it using STP through conduits crossing the roof to get across one end of the house to the other. It helped me avoid wireless extenders and meshing technologies.
In the EU at least you cannot do that, you can't use the same conduits for data and power. But it's been in the code for a long time now to have ethernet upon delivery, both CAT6a (rooms) and fiber (just a single place is enough, I think).
Personally I think the code is wrong, because the ethernet ports are next to power sockets at floor level, or at TV level in bedrooms in some countries. I think it's a niche use-case that people actually use wired ethernet to connect devices, and we shouldn't codify for minorities. I think code should include radio design, and put ports near lamps where radio design says AP should be, I think this would cater to the majority need. Minority can figure out their custom design.
The ethernet ports are used so rarely, at least in my market it is normal to get termination delivered so wrong, you can only get 100M out of CAT6A (all 8 wires connected). And no one in the market appears to understand that just testing for conductivity isn't good enough or even understand the problem when described. So consumers are happily buying that >100M Internet, but will never get more than 100M, because they have poor termination. -- ++ytti
