If we’re talking about hiring someone to run AC wires, then the cost of extra equipment can be offset by the labor costs.
(I have definitely hired a master electrician for every outlet added to my house. Definitely.)
Comment on USB-PD is a de-facto low-power DC voltage standard, with USB-C being the universal plug. Hurray!
ComplacentGoat@sh.itjust.works 5 months agoI love PoE, but there are some hard limitations to that idea. Mainly cost per meter of cable, but also in the amount of runs that would need to be completed to accomplish that. I cant splice two ethernet cables together and run one to a nearby light or other device without a switch, which means more equipment or more cable to make it work. Also, being 48v, it will have a lower overall efficiency compared to direct wiring with 110-220v, especially with the higher resistance of ethernet vs 14ga romex. That being said, I’d love to see 48v dc in home outlets.

Oh boy do I have something for you. The single pair ethernet standards. Connect 8 devices on the same line as a bus.
ComplacentGoat@sh.itjust.works 5 months ago
Didn’t realize that was part of the spec. But wouldn’t that be 4 devices? 2 wires per device for tx/rx and power +/-.
Flipper@feddit.de 5 months ago
No. It’s a single twisted pair wire to connect at least 8 devices over a minimum distance of 25m. However the speed is only 10MBit.
frezik@midwest.social 5 months ago
That would only allow PoE+, which limits devices to 25.5W. Speed would be limited to 100Mbps. Still enough for lights, though.

310m poe cat5 won’t be more as sixty bucks will it?
JasonDJ@lemmy.zip 5 months ago
For CCA.
If you give me a couple pennys, a tootsie roll, and 24 hours, I could shit out a better cable for you.
JustMy2c@lemm.ee 5 months ago
Can I videotape that?
ComplacentGoat@sh.itjust.works 5 months ago
The cost has shot up and down post COVID. Cat6 is typically the better option as it uses thicker conductors. Cat6 is 23ga iirc. I paid $85 for 1000ft on my last project
JustMy2c@lemm.ee 5 months ago
I’d buy for that price :)
