Need a little explaining. In the first example, the fire is started in the rag pile using a “rinky dink” extension cord powering multiple high draw appliances. Check. But in the second example the extension appears to be a higher quality power strip and the fire is initiated in the wall plug, not the power strip or the cable. Isn’t the primary problem is that you’re drawing 28 amps through a 15 amp socket? Would the same result happen if the power strip were replaced with a suitable heavy duty extension cord?

Yikes!!

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.

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

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.

So this is Ada and building code requirements in Canada? Not NEC code requirement?

Thanks for sharing your knowledge.

Thanks for sharing your knowledge.

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

Thanks for sharing your knowledge.

So scary, always use a licensed electrician!

Thanks alot for your all videos. Good stuff.

Awesome video plz make a vid on conductor stapler with canadian codes..some inspector here have their own versions, 2 wires, 3 wires etc

I dont use any of those heights in Ca

According to what I have seen there are not outlet height requirements in the NEC code. So, I am now confused. Please site the NEC code where outlet heights are specified.

Good information and well presented. My house was built in the 40's and I'm upgrading all the cloth 2 wire with 12/2NM-B. Since where I live requires no permits, I'll use what makes sense and ignore what doesn't. Adding outlets is a must since in 1940 they generously included ONE outlet for each bedroom but the new outlets will be at the same height as the existing ones. "The code is more of a guideline" to quote Captain Barbosa.

I have a four prong 220V generator & a 3-wire 220V condenser. Does this summary make sense? G = ground = green X = L1 = black Y = L2 = red W = neutral = white (unused in this case, as the condenser is single phase)

Now these are real offfgrid inverter chargers that use heavy duty low frequency transformers instead of those cheap Chinese made, lightweight, high frequency junk inverters that offer far poorer surge capacities, shorter like expectancies and absolutely no galvanic isolation for safety.

Boss, please see this! I stumbled onto your video in a moment of desperation. I'm currently without roughly 40% of power throughout my house. I'm unsure if it's a GFCI fault, wiring, or whatever it could be.

I would like to add a counter top plug on top of my island and plug it into a outlet inside rear of island. I live in Edmonton, AB, does CEC electrical code allow receptacles installed inside island run via AC90 12/2 wiring?

Thank you, 😊

I try to unplug it from the wall and the whole house starts beeping like an alarm

GFCI protection or AFC Fault protection?

Thank you!

Thank you!

Thank you for the information… I was under the impression that the operator always needs to wear a ANSI approved Hard Hat. 😮

I always put them at 18" to center off rough floor.

What a great video!!!!

Also good to check the other terminals, if you get more than one beep, you shorted something.

I'm pretty sure that outlets were 18"

😮😮😮😮amazing

This didn’t work for me. I can’t get the damn wires off!!!$

Great explaination

i detached the smoke detector off the ceiling, but the chirping is coming off the base in the ceiling. Is that possible?

This is unusually good! Thank you for taking the time to put it together and for sharing your knowledge.

Continuity

Thank you, are those considered subpanels ? I.e. do you separate neutrals and grounds within them?

What will be happening if i don't connected the red wire or if a capped?

Hey, what is the NEC article for switch & outlet height? And are you measuring to center of box? You didn’t specify for either of them.

Clean cut

I wish we had known about the soy in the white colored NM. A couple of squirrels got up into our attic and chewed the wires. Burned the whole house down and lost a lot of beloved pets in that one. We rebuilt and used BX everywhere. Never again will I live in a home with NM.

see how much he leaves at the receptacle dont be like me try to cheapskate the job even when the electrician said i was way too short i no listen now have nice junction box beside the panel

50 " ??? wtf I like 44" to center for switches and outlets 18" to center BTW what measurements are you giving center ??

Thanks! Can you do a video on box heights…..switches, plugs stove, counter top etc?

For those in California: Cali Building Code 1136A.1 Receptacle Heights: Electrical receptacle outlets on branch circuits (30 amp or less) shall be located no more than 48" measured from the top of the receptacle box nor less than 15" measured from the bottom of the receptacle outlet box to the level of the finished floor or working platform. *(watch your finished floor heights during rough in! ) ... Switch boxes shall be located no more than 48" measured from the top of the box nor less than 15" measured from the bottom of the box to the level of the finished floor or working platform.

🔥🔥🔥

Would the 4ft also apply to 240v receptacles in the the garage?

Thank you, great video!

This video I’m using in my powerline technician training class
