Hello The polarization of the sockets is a matter of safety , since household appliances and electrical equipment in general assume that the live is to the right of the outlet, therefore its circuit is conditioned to that point . From a simple nightstand to a sophisticated audio equipment they have a switch that cuts (cuts) the live cable, not because they know what the phase is, but because it cuts the cable that should be. It is the same situation whereby the key cuts the live in a lighting circuit. If the polarization of your shots is random, you must rewire them one by one, if they are badly armed from a group, you turn the section of the affected circuit. This security failure does not carry a direct danger, but as I mentioned it can lead to an electric shock in components or devices that we believe without voltage; It is in you to assess the risk you take, it is not much the difference that driving a vehicle with the broken handbrake, nothing can ever happen, but ...
