Great information in the video for DIY'ers thinking about "adding power". But a real wall fire would not have a completely exposed back side, hence the oxygen available would be limited in real construction and would take significantly longer than the video. Building codes add precious time to escape and are designed to keep the fire to a smoky smolder rather than a raging fire like at the end of the video. 1/2 drywall alone is rated to 30 minutes. That means this fire would be oxygen deprived for up to (and most likely very close to) 30 minutes before it would break through the drywall and get oxygen and begin to grow and look like the end of the video. Its possible it could self-extinguish. The 2x6 blocking is rated to 60 minutes so the drywall is the weak point. For example, this is why modern codes require drywall finishing under staircases, even in basements. It gives you like 5 times the amount of time to escape out of what might be your only exit. A wall with a plexiglass sheet on the "viewing" side and fireblocking foam on the cable entry points would better simulate a real wall, up until the plexiglass melts. Best I can think of is a sheet of borosilicate glass but that would be hundreds of dollars.
I think this does a good job at showing how ridiculous you have to push things past spec before they fail. If your causing electrical fires from overloading the wire, you shouldn't be working on your own stuff. Like
This should help pacify people who are worried about getting anywhere close to the limit just as much as it helps inform people to realise they should get someone to do the job properly.
@@thewhitefalcon8539 you're right. I think its crazy that homeowners will push things so far. It really does take a good bit of negligence on the homeowners part for this too happen when all other things are correctly done. It just seems crazy to me people will push things they don't understand so far that it catastrophicly falls, when it's their's and their's family's live at risk. It's good to see someone actually showing people how this happens instead of just saying trust us.
The insulation kept the heat in and let the heat soak into the wood whereas the cords were in open air, outside near to the ground and could draw cool air onto and convect away from them - IR cameras are great for showing issues like this. If a fuse is overloaded it will show hotter than the rest or damaged wire will be hotter at the damage

I feel like there is far more headroom than I realized. Still definitely want to make sure things are right. Given most of us live in tinderboxes.
Thanks alot for your all videos. Good stuff.
So scary, always use a licensed electrician!

Thanks for sharing your knowledge.
