Noise in Registration Box

Good Group .. I comment on my case. I threw a new line towards the bottom of my house, since the cables were made of cloth and were already old. Change only one sector that goes from the kitchen to one of the bedrooms. (Crossing a patio of 10 meters. In the registration box that is in the bedroom where these cables enter, it is making noise. As if the cables creak. No I see sparks but the noise is heard. I clarify that the cables that follow the lighting and the other room do not change them, just replace them. Only yesterday, I changed the cables that go down to an outlet of that box and it continues to make noise. What can it be? Any false contact of the cables that does not change? Am I changing by sectors? Thank you

You never put a patch of new cloth on old clothes, the old saying goes, it is valid for electrical installations. luck

Hello You must adjust the cables of the connected lines on the board very well, verify that before doing what follows (you may have left something loose if you were working); if everything is correct in the terminals, it is very likely that a problem in the contacts of a thermal protection, before the slightest doubt must be replaced. Identify which is the thermal that makes noise, and replace it with a new one of equal value. Under normal conditions (almost certain) everything should end there.

The problem arose when I made the change of section. I skipped the therma sometimes. Capable once a day. The therma does not make noise, what makes me noise are wires inside the registration box. Replace it thinking that, it was wrong. The terminals were tight. What is, is that the noise is only in that register box. Could it be that when passing the cables, someone's sheath has come out and it can mean something? I will check and change the other cables since I didn't have time to do it

I don't know where you are from, possibly from Mexico or Venezuela, if so, you surely don't have a differential circuit breaker and some cable may have lost its insulation and is leaking current to ground, and that leak is responsible for the noise, if so The consumption on your meter should be very high.

I am from Capital ... Argentina ... I have no differential. Can that noise be due to loss of insulation?

I discarded Argerntina, because of the power cutter, since a leak is very likely, but if the pipes are metal, or the grounding is bare, or the line wires between them have been pinked, but it is more difficult. Look at the meter to see if you detect high consumption right now.

I'm going to feed the registration box that makes noise by skipping the cables (I'm going to do it on the outside) that come from the pipe to know if any cable that is inside the problem is the problem and direct food. I am going to try

I already found the fault. There were some burnt wires that sometimes touched the pipes and made me jump the thermal. Since it had no differential, the leak was not instantaneous. Thanks nastor for the information
