I had no idea there were different types/ratings for these wires… I used standard cat6e everywhere in my house even w/poe all wires are in walls & attic… am I safe… should I be worried at all?

I didn't read up on my local code, but the general reddit wisdom was that: * Corp building installs have diff requirements than homes. * And then even within homes, it's a question of how long the run is. Somewhere around 50-100' is usually short enough that there are no regs. Plus minimal concern about jacket off gassing in the vents for such short runs.
