In many cases that we find and EMF issue, mainly ELF magnetic fields issues, in a house it is because of poor planning that did not take info account the Electro-Magnetic Radiation. In most cases most issues would have been avoided if the house was planed using some very basic roles:
Before you a riff summary of several electric issues, that are caused by bad design, bad maintenance and that can cause ELF EMF exposure problems.
Sometimes, over the years, over heating issues accords over the wires, usually with the Natural wire, usually need connection points. When this happens the electrician usually cuts the burned tip of the wire and reconnect it to the connections. Over the year this wire will be cut short in a way that will not allow it to be reconnected again. In this case the electrician have 2 options, take out the old-short wire and put a new longer wire, and option 2 , connect to a Natural (pr Phase) wire from a different cricket. This will create a condition in which the Phase and Natural wires are not wired together side by side, and where the magnetic field created by each wire will not reduce the other, and will result with higher ELF magnetic field values.
If an electioneer will mistakenly switch between the "Natural" and the "Ground" wires, most of the times it will cause the Safety Electric Residual-current device switch will cut the electric supply, but in some case it will not and electric circuit will continue to work. One thing will change, now the "Ground" wire will conduct electricity and will produce ELF magnetic field, usually with no "Phase" wire to create an opposite ELF magnetic field to reduce the overall ELF EMF from the wires. In addition, now there will be elevated ELF EMF from the "Phase" wire that has no opposite ELF magnetic field, created by the "Neutral", to reduce the overall ELF EMF from the wires (In case that the Ground and Phase wires are not going side by side). This will result in higher ELF EMF from the Phase wire and a very big ELF EMF from the ground wire.
The problem can be found with the use of ELF EMF meter, and can be fixed by a professional electrician.
In some countries is it custom to have a grounding connection to more than one of the following: ground pool, , a metal water pipe, the house foundation and to the electric company. a ground connection to the electric company and to the water pipes may cause the creation of "ground loop" and can result in higher ELF EMF fields in and around the house.
This can be found using an ELF EMF meter, by seeing high levels near the water pipes or the house foundation.
In order to fix it it is required to have an electrician disconnect the grounding form the electric company or install a plastic water pipe section on the income water pipes. This should be done only after a proper ground was installed and tested.
