I think you really need to understand how a GFI works... Let me ask you this, why do YOU think it should trip when water is poured over the hair dryer?

Joe,
Does the hair dryer have a 3 wire cord? Is the drain piping metallic? If the answer to both questions is no, there may not be a ground fault path. If there is no ground fault path, there is no reason to expect the GFCI to open the circuit.

Kid's, Don't try this at home!

It would trip if it detected a 3-6ma current mis-match. Contrary to popular belief water is not a good conductor. If you became the conductor between line and ground it would trip no problem. Now if you threw that hair dryer into a sink of salt-water it would more than likely cause a ground fault. But, it still might not pop the gfci if both L1 and L2 are instantaneously loaded (equal current). BTW, I wonder what the nice people at that holliday in think about using their hairdryer that way?

I can se why a GFCI or ALCI device would nott rip under this type of test, however doesn't that hair dryer have an IDCI (442.41)?
This type of immersion would certainly be protected against with an IDCI.

Bryan,

I didn't see any of the units complete immersed in the water. I believe that that immersion detection device is in the handle that was never under the water.

Instruction not followed!

The comments here by others helped to answer the question, and I agree.
I asked for comments, and was looking for some replies.
Will you share yours, or give the reason why you feel the device did not work?
I have other examples were the appliance did in fact trip the ALCI, and GFCI so the possibility that the path was there, or the device was faulty in the video clips are likley.
Most of these types of appliances make it very clear that they are to be kept away, as shown in the image here:

Joe,
Did you test the wall GFCI with its test button? If so and the GFCI tripped, then there was not a ground fault path in your sink test.
Don
Were the other examples in that same sink? If the other examples were not in the same sink, then you cannot compare them. Some installations may have a ground fault path while others many not.

It's quite clear why the GFI didn't trip, I'm just wondering why your making a spectacle of the fact that it didn't... I'm just wondering if you think you found a defective GFI or something? Not sure what your point is, thats all... Thats why I asked the question I asked... Because If you really knew why I GFI trips, I don't believe you would have even posted those movies... At least stick your hand in the sink first...

You first. But I get your point.

Well I couldn't get the video to play so I'm not sure what the discussion is all about, but Stickboy, I'm pretty sure that Joe knows how a GFCI works.

I decided to delete them since he didn't see the need for any meaningful discussion, and wasted his, calling the videos a spectacle, and wasted our time with his nontechnical replies, instead of giving his reason why the units did not work.
Put your hand in the sink and try it, I am not going to put my hand in the sink!
It would be a good idea to get the book by "Earl Roberts, Overcurrents and Undercurrents all about AFCI's and GFCI's.

I am going to lock this thread. With the deletion of the video, the thread is a wreck.
