# differential jump how it works I jump this doubt watching

This post was translated, if you want to see the original version click here
https://www.youtube.com/watch?v=0jQPE3ssjlEhola friends I jump a doubt it turns out that I am watching a video where we talk about the differential jump and watching the comments of that video a person answered the following // I repeat that said the user // if someone takes both phase and neutral wires one in each hand does not skip the differential that is due to the resistance of the body they are high for the differentials is the same as that a light is turned on and an appliance is connected therefore do not jump and keep saying that you have to keep that in mind /// for me that is not so because I touched a cable or the two cables the result is the same skips the differential

Do not do the test, the differential jumps if there are, among other issues, grounding. Regards

it's not to do the test it's just to know if what is said in the video is like that

I do not remember the video, but I can assure you that if you take two cables of different polarity and being isolated from ground the differential does not jump

So regardless of whether it is a cable that you touch or both at the same time while you are isolated from the earth, do you not jump?

The first thing we must keep in mind is the reason why the breaker or circuit breaker is called that. Its name is due to the fact that it is sensitive to a differential current of low magnitude (30 mA). Differential current is understood as the subtraction (Algebraic) of those circulating through each conductor, which, if there is no anomaly, should be zero (0). If this subtraction is different from zero and reaches or exceeds 0.03 Amps, the mechanism that relieves the switch is activated by de-energizing the downstream line. In case of direct contact or ... (continue in another)

## 3 Proposed Solutions

... indirect, by the conductor "alive" (phase) by this will drain a current that does not circulate through the neutral therefore will trigger the dsyuntor. In a few words your friend is right, as long as he is isolated from the ground. Don't Experiment With This! It can be fatal!

Read the fourth comment of the video by Jorge Abbiate

SOLUTION ACCEPTED
I was watching the video and it is clear that it is investigating its operation.
I think you should read the characteristics and recommendations of the manufacturers.
For something like additional are the current sockets with protection for children that do not allow to introduce a single leg or sharp element.
Whenever there is a difference in current between phases it will jump from the differential, that is why the javelin and grounding is also so important.

read the fourth comment of jorge abbiate i mean that comment by that do this question

It does not load the comments, but I insist that if you touch the two poles you will receive all the voltage without skipping the differential. This safety accessory is something else but not definitive. If there is any damage to any device and discharge to ground, it will jump avoiding a human accident. There are some scientific sheets of how much the smoked body resists and the consequences according to the direction of current flow through the body. If the circulation occurs from arm to arm it passes through the heart and is usually fatal, if it is from arm to limbs>

ok thanks for getting me that doubt

Lower maybe you save yourself and if it is by the head .... puffff cooks your brain.

The differential measures the differential between the phase and the neutral. Normally, more current flows through the phase than the neutral. But it will also operate if the neutral has ground discharge, since the small voltage that the neutral has, may be sufficient to make it operate. But resistance to ground must be much less. For example, with 5V in the neutral, there must be an earth resistance of 160 ohm for the 30ma to circulate. As the body has greater resistance, it does not operate when touching the neutral, even if it is grounded.

And if you take both cables at the same time, I ask or why in the video that I uploaded, someone commented that touching wires at the same time the differential does not jump

I mean the comment of Jorge Abbiate

There are two cases, one that does not operate and another that does.
If it is isolated from earth, it will not operate.
But if it is in contact with earth, in addition to circulating current between the phase and neutral, which becomes a load, it will also discharge to earth making it operate.
