Features of GFCI

Features of GFCI

Because GFCI detects ground faults, it can also prevent some electrical fires and reduce the severity of others to interrupt the flow of current. The working principle is as follows. In a household wiring system, on a power outlet, under normal circumstances, the current of the hot wire and the neutral wire (Neutral) should be equal. GFCI monitors the current difference, but the difference is greater than 6 mA ( Milli　Amps) (according to the UL943 standard, when the leakage current is 6mA, the disconnection time is 25 milliseconds), it can pass 0.025 seconds (according to the UL943 standard, in the case of 500 ohm impedance, the leakage current is 4-6mA Cut off the power at the moment of disconnection time), thus ensuring personal safety. The GFCI interrupts power faster than in the blink of an eye to prevent lethal power. You may receive a painful shock, but you will not be electrocuted or receive severe shock injuries.

All GFCIs should be tested every time they are used to ensure that they are working properly and to protect you from fatal shocks. GFCI should inspect after installation to ensure their work and properly protect the circuit. To test the GFCI socket, first plug the nightlight or lamp into the power socket. This light should be on at that time, press the "TEST" button. The "RESET" button of the GFCI should pop up and the light will go out. If you say the "reset" button, it will pop up, but the nightlight is not off, and the GFCI has been improperly wired. Contact an electrician to correct the wiring error.
If the "reset" button does not pop up, the GFCI is defective and should be replaced.
If the GFCI function is intact, after the light goes out, press the "reset" button to restore the power supply to get out of the way.　GFCI has four types: GFCI plug, GFCI socket, GFCI circuit breaker, online GFCI.
