HELLO EVERYONE, MY CONSULTATION IS THE FOLLOWING: I have an electrical panel in my house in which the connections after the circuit breaker are made in a bridge, that is, the first thermal power feeds the one next to it and is in turn next to. The problem is the following: when under a thermal and I measure in the corresponding circuit and it throws me that there is 55 V and if also under the previous thermal, that is to say the one to the left of this, it gives me zero. Is it possible for the circuit to be charged by the way the installation is made? as far as it is badly done because it should not be on bridge.
Another problem I have is that in an outlet I was fixing, he kicked me because the poles were inverted (in the color of wires) and the circuit breaker did not jump and the installation has the ground wiring. Why is it that I don't jump?
From now I appreciate the possible answers.

Hi Walter
What you say about the bridge connection is called "garland" and this is prohibited
I do not know how you have measured voltage or at what points exactly, but what is going to happen is that one of the connections of the bridges loosened and the voltage drops to 55V, another thing that can happen is that one of the thermals that feed those 55V has a damaged pole and the voltage drop is within it
when cutting the previous thermal gives 0V for the simple reason that you must be eliminating the tension when opening the circuit that feeds, so it is important that you describe exactly how everything comes and what you do, whether it is with photos or a better video so that we can evaluate better
It can also be problems of induced voltage if the circuits of each thermals go through the same pipe.
the issue that you received a shock due to the inverted polarity and the differential did not act, two things:
1) For your peace of mind, check the differential by pressing the TEST button which should make you disconnect instantly, if you do not disconnect or take a while to do it, it does not work and you must change it.
2) a differential does not prevent the person or animal from receiving a discharge, which prevents it from receiving a discharge of dangerous levels for that person or animal, this means that you can receive a discharge that if it does not exceed the limit established by the differential, this will not operate,
comment any questions

Thanks for the answer ... I commented: the issue of thermal is with all, if under one ... example one of shots, I go to the shots of that thermal or circuit, I measure them with a tester and it gives me 55 v. followed by this and under the thermal on the side (left side) I measure the sockets again and it gives zero, but the thermal that I have just lowered when I measure it at its poles or at the sockets or light depends on the circuit , also measures 55 v. and so on ... and for this last thermal to lower me from zero when I measure it, I have to lower the previous one to this.
The circuit breaker is fine ... I tried it and cut it.

Ok ... the connections as you drew them are fine although that does not imply that this
The way it is connected does not have to close or open a thermometer to affect the next one, so I am inclined that this garland connection is affecting it and what happens is translated as voltage variations as they increase or decrease the charges

I suggest you redo all those connections, if you can incorporate a better distribution terminal because it would be so regulated. If you cannot do it with cables but the important thing that there are no cuts in them, do it with a single line (not 2) of at least 6 mm2 of section and without cuts,
Another important point is that you should put protection on that differential. Is there any therma between the differential and the meter?
