GFCI Lab Tests

[Roy Q.T.]

excuse me:
Does anyone know how GFI technology was tested ? and how they know the
results of a GFCI classic bathroom accident or attempt isn't harmful to
humans.

Having my own notions I'm curious, oh', by the by last I saw a monkey
being used for tesing was in the 60's.

actually I wish we could set up our own web based lab and rest assured
from our own tests.so i'll search around too.

GFI's are tested by generating various different types of leakage
currents, or simulating them in its current transformer.

If you mean how do we know what effect the different currents have,
it's something that many regimes around the world researched heavily
during the last century, notably Nazi's during WWII, although I believe
the Nuremberg Trials or subsequent treaties actually forbid the use of
such Nazi research after the war.

 

[Roy Q.T.]

i don't remember, nor have seen any such reports but it is possible that
data from nazi experiments may have lead to modifications and & design
oblectves regarding device current, in the shadow of deaths by
electrocution in other parts of the world.

Hiltler was one bad dude., with the abundance of rats in our sewers i
don't see any need for human testing.

If GFCI's were developed back then they were most likely tested with
resus monkeys in the US.

resus monkeys in the US.

GFCI development wasn't until 1970's, years after the effects were
known. In the UK, we had earth leakage circuit breakers way before
then (I think from late 1940's in some homes), but they worked
differently and were for protection of wiring rather than people.

The effects of electric current are vastly different between species,
and humans for some strange reason are amongst the most resilient.
Some farm animals can be electrocuted by currents you can barely feel
and voltages you would handle with bare hands without any concern.
Areas accessible to livestock have special electrical safety
requirements in the UK because of this.
