How Ground Protection Works ?
 |
Two children, ages five and six, were electrocuted in a city when a plugged-in hair dryer fell into the tub in which they were bathing. A three-year-old girl was electrocuted when she touched a faulty counter top. These are some of the very common news nowadays. Undoubtedly, electricity is one of the basic need nowadays, it can lead to many deathly hazards. For that one should take extensive care.
Houses that have serious ground faults are the main reason for the electric shock injuries. Usually, shock is experienced when an unintentional electric path between a source of current and a grounded surface is provided. So, to avoid accidents caused due to fault in electricity, one should install GFCI in their homes.
GFCI stands for Ground Fault Circuit Interrupter. It is basically an electric device that is installed in the household branch circuits to prevent electrocutions. These not only prevent the fatal electric shocks but also lower the risk of electrical fire.
The working of GFCI is very simple. It consistently keeps a close watch on the incoming current to a circuit and the current returning to that circuit. If it finds that the current flowing through the circuit has increased or decreased, it will immediately switch off the power supply to the circuit and saves the circuit.
This is how the GFCI interrupts the power and prevents the shock. The greatest advantage of the device is that it switches off the power as quickly as blinking an eye.
However, these are chances when you unknowingly touch the electric wire at the time when you are already touching the metal substance. Let us discuss it in more detail. Sometimes, when an uninsulated wire in the appliance comes in contact with the metal cover or the case, it gets charged with the electricity. As soon as your body comes in contact with the appliance as well as the metal, an electric shock is received.
However, if the appliance is plugged in to the outlet protected by a GFCI, the power will be turned off immediately before causing any accident.
GFCI should be installed at places like bathroom receptacle circuits, garage wall outlets, kitchen receptacles. Also, a GFCI should be used whenever operating electrically powered garden equipment. Homeowners those who have not installed this wonderful device at their places, should consider having them installed. These are very essential for the safety of you home and the family as well.
