The electrical system that goes to our homes, if the use of electric system 1 phase, usually made up of three cables:
The first is the phase cable (red) which is a power source back and forth (positive and negative phase phase back and forth continuously). This cable is a cable that carries power from the hydroelectric (PLN for example); These cables are usually called hot wires (hot), to be compared as the positive Pole on the direct current electrical system (although in physics is not right).
Second is the (black) cable neutral. This cable is basically zero voltage reference cables, connected to the soil in power plants, on specific points (on electric pole) electric network cabling is connected to neutral to ground voltage on the transformer down primarily from high-voltage channels three lines into three phases plus line line ground (four lines) that will be distributed in houses or other.
To address the leakage electric current of the equipment each home installed cable ground (black) connected by a metal plug ground to put together with the neutral cable channels of electric nets mounted on a distance closest to the electric meter or tool close to switch.
In the events of Hurricane Electric space (space electrical storm) are great, there is likely a current will flow from the underlying soil to reference other land that far. This natural phenomenon can trigger large-scale lamp dead events.
Third is the ground or Ground wires (blue, green, black and red colors aside). This cable is a zero reference in the location of the user, which is connected to ground (ground) at the home user, these cables really come from the metal that was planted in the ground in our homes, cable is a cable that is connected to the security body (chassis) alat2 electricity at home to ensure that users of such equipment would not be subjected to electric shocks.
The third cable was rarely fitted to dirumah-rumah inhabitants, be sure the technician (instalatir) electric cord you attach the ground (ground) on the electrical system at home. This is important, because the installer is an absolute requirement for your safety from the hazards of electrical shock that could be fatal and also several power tools that are sensitive will not work properly if there are electrical induction that appears on chassisnya (for example, due to the effects of current Eddy).
