1. Why are IEC/Edison cables so thick if Ethernet can carry the equivalent power? 2. How does PoE compare to Powerline Networking?

- otterley 1y agoNo Ethernet cable that I’m aware of is capable of carrying anywhere near 15A of current. Even type 4 (90W assuming 57V) is 1.5A.
- gwbas1c 1y agoAnd don't forget that, with ethernet, every device needs its own run of cable, its own port at the router, ect, ect. Normal power cables support multiple devices.
- skinner927 1y ago1. Assuming IEC refers to cables we plug a desktop PSU into mains/wall: IEC can carry up to 1800w vs 100w PoE++ 2. Powerline networking is considerably slower and less reliable than CAT5/6. Additionally, building code for running power lines is much more strict than low voltage CAT5/6
- dlgeek 1y agoNerdsniped: You're describing a IEC 60320 C13 cable - they're technically only spec'd for 10A, which means you're looking at ~1200W, not 1800. (However, UL will list them for the full 15A -> 1800W, and I'm sure plenty carry that. And for that matter, I suppose you can get twice that in Europe on 240v...)
