Household Electricity

Two phases in my contacts

When bouncing or turning off my pads from the charging center of my electrical installation I check the line in a bedroom and notice that the two wires were phase and check my contacts throughout the house and when checking with the dedarmador look for poles the same marks me two phases

That is possible if by axis, you have 120V and you use 2 phases of 60V without neutral ... usually happens in naval installations

Hello if it only happens when you boot the pills, the most likely is that the pills are sectioning the neutral instead of the phase this would be a SERIOUS error which must be solved immediately, once this is verified, a professional must reverse the polarity the other possibility is that your installation is with 2 live lines but when you throw the pills, the phases should disappear in everything that is after the frame except for two possible causes: 1. That there are circuits that are direct, that is, that do not go through the panel 2. That there are active lines very close and when you cut the power, a voltage is induced in the conductors, that is solved by separating the section where they pass together regards

I thank you if they connected the neutral wings to me instead of the phase. Excuse me, I would like to correct myself that it is better to pass the neutral directly or connect it to the neutral bar. And it is supposed to be the only correction or this change affects ladder dampers and contacts

The neutral goes to the neutral bar (which is not the same as the physical ground) and the phase goes to the pads
Due to the high risk that this task means, it should be performed by someone with experience or ask the distribution company to interrupt the supply for maintenance tasks

Hello, if you say that you turn off the pads and still have phases in the cables throughout your home, it is very likely that you have poorly polarized installation, from your load center. You must use a volt amprerimeter, and check the voltage that exists in those cables that you measure with a pager, and find voltages above 90v. you should check your load center, and if you have a main switch, do the same. I remind you that in two-phase systems, there are returns in 220v equipment. that can give false readings, but it will never happen, or should happen, if the thermomagnetic pads are turned off, unless they re-direct direct circuits that do not pass to the load center, greetings. alualo.

thanks if the problem is in the load center abusing a little there I can start a physical ground or I have to bring it from the meter thanks

Hello, look at the physical protective earth you can put it from the load center, remember that you should not communicate with the other physical earth of the meter, (if you are in Mexico), that is, you must have 2 physical land, 1 service at the foot of the meter to land the neutral, and 1 protection inside your entire installation of your home, greetings
