Cat 5 wiring (2025 Update)

A house is very different than a typical commercial building, and in a fire, behaves differently. You don't need a plenum, to benefit from the safety offered by plenum rated cable in a home installation. The higher cost of plenum cable to deal with it is likewise, not a big deal in a home, where you aren't going to need miles of it as you might in a commercial installation.

Don't put the cheapest locksets available on your doors, either.

I was referring to crimped connectors. The fact that you prefer something else (punch down) doesn't mean crimped connectors don't exist.

The point is in a house there are so many other sources the relatively minute amount of Cat-5 cable insulation is absurd to think is a significant factor in comparison.

It's enough of a problem that it's worth using the better cable. The fumes it gives off are VERY toxic, not just a little toxic.

If you say so--I have a hard time believing it would be significant in the scheme of things in an actual fire.

I am sure that is true. I plan to go outside my house catches fire.

The cat is there to chase the rat. It's the rat that does the wiring :-)

My understanding is that the plenum fumes are _more_ toxic than those of the non-plenum cable, but there's less of them and they take longer to get started -- again, it's not a simple choice. In a commercial setting, you would expect the sprinkler system to activate before the plenum-rated cables ignited, but in a house there's no sprinkler system.

Pop quiz:

Which is more deadly: Clorine gas or Cyanide Gas?

I find these connectors easy on my 51 year old eyes ...
