I am sure it is overkill and very unlikely but penetrations in sill plates between floors should be filled with a fire rated spray foam or caulk to slow or prevent smoke or fire by preventing airflow.

Plenum is not needed for in wall installation, only necessary if it is ran through an air handling space, such as a vent or return air.
This guy's channel has a ton of good pfSense and netgate info, and did this wall-fishing video a number of years ago which may help.

Yeah, Plenum is only used in air handling spaces such as commercial dropped ceiling where the airspace above the ceiling is used as an air return or if the wire passes through a return airspace in a wall or a duct.
Connections are easy.
Google TIA/EIA568A or TIA/EIA568B diagram.
Make sure you follow the same standard on both ends of the wire, if that wasn?t obvious.
The plenum rated cable is worth it imho, I'd rather have something less toxic in a fire.
If your house has burnt enough that the wires inside the wall are burning you have serious issues. The difference with plenum is that when it burns it burns slower and releases less smoke hence the reason for having to use it office buildings with plenum airspace ceilings. It's a waste of money in a home, beside the fact that you shouldn't be running wire through a duct or return space anyway. Using your HVAC ductwork as a wire raceway is a shitty idea.Quote:
