It seems to me like the GFCI worked just fine. Unless you can get 5 mA to flow through a body-like object you've not proved the GFCI to have been useless. Side note: tubs are grounded (at least where I live) so it would have popped the GFCI instantly.
@chillydogization modern tubs are made of fiberglass. Water lines are pex and drain lines are pvc. As you saw in this video, modern bathtubs nullify the effectiveness of gfci protection
Back in the 1990s I was hired to paint a bathroom and the homeowner knocked off a hairdryer into the toilet it was humming and popping the husband reached for the hairdryer the wife jerked him back in a split second and jerked the cord out of the wall. This was before GFI times. My mother's boyfriend got a king sized airbed and unboxed it and was trying to think how to inflate it He went and got my mother's Hairdryer and it ran & ran then quit he burned up her hairdryer oh she was P#$$#D it's nearly 30 years ago and I remember it like twas yesterday both events with hairdryer in water and burning up trying to inflate a king sized airbed.
It doesn't, that's what this video is showing you. Neither the built in gfci at the end of the cord nor the installed one in your wall would trip in this instance
But how dangerous are the currents in the water really? Why would the current not just go directly to the neutral wire inside the hair dryer, instead of taking a long trip through the water and even your body?
The electric current always goes where the resistance is lesser. When the dryer is in the water, there is absolutely 0 electric current inside the water as it goes preferentially through that copper wire which has a very very low reistivity. Ofc if the cable got damaged, all the current will go in the water, and to you. To convince yourself watch this ruclips.net/video/F2036TWWI_E/видео.html
Because the water in the plastic tub is "floating", meaning it has no reference to ground, the GFCI won't trip because the current flowing from ungrounded "hot" conductor to the grounded "neutral" conductors is balanced. Since there's no leakage current greater than 5 mA (+/- 1mA), the GFCI won't trip. However, once the grounded copper wire is inserted into the water, which is obviously bonded to the source, then it becomes a parallel path for current greater than 5 mA which imbalances the circuit and trips the GFCI, just like it's supposed to work.
@@eanhickok8984 I would agree a person inside the plastic tub would be in a parallel circuit with the current flowing through the ions in the water. The resistance of the human body is normally taken at 500 ohms, but that's if the skin is dry but will much lower when fully immersed in the water. As we know, current will take all available paths and not just "the path of least resistance". Sure more current will flow through the path(s) with the lowest resistance but some current will still flow through the other paths with higher resistance. The subsequent voltage drop across each of parallel branches will be directly proportional to the resistance of each parallel branch.
Wouldn't a human body in the tub have resistance therefore causing an imbalance in the circuit and tripping the GFCI? The ground caused an imbalance, a difference in current, tripping the GFCI. The GFCI is designed to sense an imbalance and with a body in the tub would cause the GFCI to operate.
Except you’d be totally fine if it fell in. A blow dryer in normal bath water wouldn’t kill you, maybe if you have a heart condition and there’s a short in the dryer, but other than that you’d be fine, there’s tons of videos that prove this.
Well, since the bathtub is insulated, there is no way the current will go through you. There are no such things as "circulating currents" in the water, the current is really not moving with the water as u probably think. The cables in the motor winding and the heater are so close together that the current goes straight to the other terminal. And if the bathtub is connected to earth in some point, or you are touching something grounded... Well then the GFCI will pop, saving you. So it is working, and this video is nonsense. Also here where I live at, we have to have our bathtubs and shower corners grounded through drains. So that would be an answer.
The tub is insulated, but the water, with you in it, is conductive. And yes, the current will travel throughout the water. This can be tested with proper ppe and tools, but is not something you should try at home. You should also be aware that grounding the drain grate or any other part of the drain is not a part of the NEC and is not a common practice everywhere, whether it is where you live or not. It's also entirely possible that the entire drain assembly could be made of plastic.
I think they could coat the inside plastic of the hair dryer in metal, either with a foil or tape or paint, and then connect that to a grounding pin that's my solution.
Thanks for the video, Now I’m off to install one in my bathtub” to make it a jacuzzi”
😂😂😂😂
He HeHe it will make it a mini jacuzzi it isn't only a jet but a heater plus you get tickled.
@@chadcrawford1502 it also blows…so you get heat, blown and a tickle 😂 maybe I will bath in salt water or add some lemon juice” for a better tickle.
@@ebperformance8436 That's not funny. It's dangerous. Somebody could take this seriously and get hurt.
The voice sounds pretty cool. I could imagine this guy saying “SIT DOWN children and SHUT UP!!!”
I am SO happy with this video.

How can you ground a tub made of fibreglass?
@@HorseMeal Interesting; I didn't reallize so many tubs are fiberglass; I was refering to metal ones.

What if you make salt in ? It becomes more dangerous because the electricity can move better around ?
Honestly the difference wouldn’t be crazy. But who tf showers in salt water🤨
@@jakobachtenactually the salt is what makes the water conductive in the first place. Distilled water isn't conductive. The salt comes from your body
What about the tap and drain? Arent those connected to ground?
How about providing earthings in tubs ? Like they do to metallic objects ?
Because the tub isn’t a metallic object
@@HorseMeal omg, it's been 4 years and i js realised how dumb i was ☠️

The bathtub already has a big old ground sticking out of it in most cases.
The first GFCI has no Ground connection. Kindly explain how the TEST BUTTON on the dryer GFCI works? Again, no ground connection.

Current takes every available path. Doing this while inside the water would be fatal.

Are you in circuit? Yes I would think you make a parallel resistance with the water

Resistance does not equal "imbalance". The heating element inside a hairdryer is also a resistor, for example.
Oh damn it so I can't accidentally kill my wife this way
Don’t have electrics in the bathroom?
where do you dry ur hair then?
@@roebunnybby in the bathtub?
