GFCI(ground-fault circuit interrupter)


   A "GFCI" is a ground fault circuit interrupter. A ground fault circuit interrupter is an electrical device. The GFCI is designed to protect people from severe or fatal electric shocks because a GFCI detects ground faults, it can also prevent some electrical fires and reduce the severity of others by interrupting the flow of electric current.
   In the home's wiring system, in the regular situation the current of HOT and NEUTRAL are equal, the GFCI constantly monitors electricity flowing in a circuit, to sense any loss of current. If the current flowing through the circuit differs by a 5 Milli Amps from that returning, the GFCI quickly switches off power to that circuit in 0.4 second. The GFCI interrupts power faster than a blink of an eye to prevent a lethal dose of electricity. You may receive a painful shock, but you should not be electrocuted or receive a serious shock injury.
   All GFCIs should be tested once a month to make sure they are working properly and are protecting you from fatal shock. GFCIs should be tested after installation to make sure they are working properly and protecting the circuit.
To test the receptacle GFCI, first plug a nightlight or lamp into the outlet. The light should be on Then, press the "TEST" button on the GFCI. The GFCI's "RESET" button should pop out, and the light should go out.
   If the "RESET" button pops out but the light does not go out, the GFCI has been improperly wired. Contact an electrician to correct the wiring errors.
If the "RESET" button does not pop out, the GFC1 is defective and should be replaced.
   If the GFCI is functioning properly, and the lamp goes out, press the "RESET" button to restore power to the outlet
The CFCI type
   It has four types: GFCI plug, GFCI socket, GFCI circuit breaker and on-line GFCI
The GFCI application
   The GFCI wide use in: High Voltage Electric washing machine, Electric mowers, Electric water pump, Large electric bath, Electric Harvester, Electric water mill, Electric cutting machine and Hand-held power tools so on.
The GFCI product
   "Plug-type leakage protection switch" (GFCI products), is a new products to exports of North America, Canada and other country, the input AC voltage 120V/60Hz, Rated output current of 15A-20A, on the ground leakage current of 4.0mA-6.0mA, tripping time ≤ 25ms, can quickly cut off the power protection of personal safety. Its most prominent feature is the use of AC voltage range: 102V-132V/60Hz, can work in +66 ℃, -35 ℃. And can withstand 6kV/3kA high impact and do not damaged at twenty times. the durability life test up to 3000 times.
