My uninformed take on this is that its almost impossible because countries have different power standards. Of course i may be entirely wrong, or correct but with an entirely incorrect reasoning. Please people who actually know correct me below
We could make low voltage DC wiring a thing inside homes.
The main problems is high amperage required to get the same wattage and the difficulty to change voltage with dc; coming from someone that has a small workshop running out of 12v dc from solar panels and batteries
It depends on what you're running, but I used to work for a low voltage lighting company. We did mostly 24vdc.
PoE works really well, data and power over a single ethernet cable for various low voltage devices. I have PoE powering network switches, WiFi access points, doorbells, cameras and raspberry pis.
For low power, sure, but refrigerators and lighting are going to require thicker cabling. But you could reuse 14/2 romex for 24 volts and get like 10-20 amps, depending on the distance.
Unfortunately, you can't always trust line voltage wiring to make sense. Sometimes they tie neutrals together across circuits, sometimes they reverse the colors of the wires, and sometimes the electrician just didn't give a fuck about excess wire and there's like 50 extra feet of looping cable for no reason.
