GFI tripping

[jwelectric]

You certainly do like to spit hairs and hang on the literal word.

Can you have current without voltage?

No but you can have voltage without current. It is not splitting hairs but the facts.
Induced voltage will not trip a GFCI device
Want to trip a GFCI device there has to be a difference in the current. The voltage plays no role what so ever.

Hypothesis
A hypothesis is an educated guess, based on observation. Usually, a hypothesis can be supported or refuted through experimentation or more observation. A hypothesis can be disproven, but not proven to be true.

Theory
A scientific theory summarizes a hypothesis or group of hypotheses that have been supported with repeated testing. A theory is valid as long as there is no evidence to dispute it. Therefore, theories can be disproven.


Law
A law generalizes a body of observations. At the time it is made, no exceptions have been found to a law. Scientific laws explain things, but they do not describe them. One way to tell a law and a theory apart is to ask if the description gives you a means to explain 'why'.

Above are the definitions of Hypothesis, Theory, and Law as it pertains to science.
Math is a law of science.

The laws of current flow (Ohm's Law) state the difference between current and voltage. Only one of these will have any effect on a GFCI device and it is current.

It is not a hypothesis nor is it theory that current is what opens a GFCI device but it is the law of current flow that states that current will open a GFCI device.

It doesn’t matter if you agree or disagree but the law of current flow does not change, it remains the same. What opens a GFCI device is a difference of 4 to 6 milliamps of current between the conductors.
Agree or disagree will not change this fact of law (Ohm's Law).

Very Nice, JW.

Have a Great Day.

The law always applies, but the Chinese-made GFCI fails often out of the box.

You might need to spend more money.

Personally, I would NOT plug any "critical" appliance, such as a freezer or sump pump, into a GFCI outlet. I would use a "single device" receptacle so an extension cord or tool could NOT be plugged into the unprotected receptacle, REGARDLESS of whether it met code or not.

Good Point hj,

I have tested many Electronic devices that were bought and used by our government, as per the specs of the
device being purchased with Your Tax Dollar.

You would be surprised to see how many devices Failed the manufactures spec, and we bought them anyway,
knowing they were Junk.

Your Tax Dollar at work...
