caused by ground fault hazards. The operation principle is quite simple: current flowing into the hot wire equals to that returning through the neutral. The GFCI uses its internal current transformer to compare both currents and, should there be an imbalance, to detect that there is a leakage somewhere in the circuit.<\/p>\n<ul>\n<li>Trips at: 4\u20136 mA of leakage (the critical threshold where people get shocked)<\/li>\n<li>Speed: ~1\/40 of a second (25 to 40 milliseconds)<\/li>\n<li>Forms: GFCI outlet, circuit breaker and portable GFCIs for sites<\/li>\n<li>Not overload protection: The GFCI does not take over the function of a circuit breaker<\/li>\n<\/ul>\n<p>Hence, following the standards for ground fault protection is so important because the National Electrical Code (NEC) has been requiring ground fault protection for years.To understand the standards and how GFCIs are engineered, our deep dive on the <a href=\"https:\/\/huyuglobal.com\/ru\/blog\/gfci-stands-for-ground-fault-circuit-interrupter\/\" rel=\"nofollow\">GFCI full form and how it works<\/a> covers the device in detail, our comparison of <a href=\"https:\/\/huyuglobal.com\/ru\/blog\/circuit-breaker-and-ground-fault-circuit-interrupter\/\" rel=\"nofollow\">circuit breakers vs GFCIs<\/a> shows where each one belongs in your system, and if you&#8217;re sourcing protection hardware, the <a href=\"https:\/\/huyuglobal.com\/ru\/product\/vrl11b-type-b-rccb\/\" rel=\"nofollow\">VR-11 RCCB series<\/a> is a typical example of how residual-current protection is built into modern breaker form factors.<\/p>\n<h2>\u0413\u0434\u0435 \u0442\u0440\u0435\u0431\u0443\u0435\u0442\u0441\u044f \u0443\u0441\u0442\u0430\u043d\u043e\u0432\u043a\u0430 GFCI<\/h2>\n<p>Ground fault protection is necessary whenever there is a risk for shocks, which occurs mainly when close to water, outdoors, or when people are in contact with ground surfaces.

The general steps are as follows:<\/p>\n<ul>\n<li>Determine the fault: If the GFCI or breaker keeps tripping, the problem lies with that circuit. Unplug everything from the circuit and reset it to see if it still trips. If it does not trip, then there is a problem within the circuit itself; if it does trip, the fault lies within the fixed wiring.<\/li>\n<li>Find the fault through deductive reasoning: Plug in the devices one at a time to see which device causes the GFCI to trip.<\/li>\n<li>Examine the receptacles and fixtures: Shut off the power to the panel, open the outlet box, and inspect it for any loose wiring, damaged insulation, hot wires, grounding wires or moisture damage.<\/li>\n<li>Look for moisture: Water is the leading cause of ground faults in bathrooms, kitchens, basements, and outdoors. Dry out the box, repair the leak, and reseal it.<\/li>\n<li>Make the fix: Address the problem itself, whether it be repairing the tape, replacing receptacles, or replacing frayed wires.<\/li>\n<li>Test the GFCI: The GFCI should now be working. Press TEST and RESET on each GFCI unit to make sure they are working properly. If you have an older GFCI (over 10 years old) or one that won\u2019t test properly, then it is time to install a new one.<\/li>\n<li>Contact a qualified electrician if the problem persists. A constant ground fault somewhere in the fixed wiring may require using a multimeter or megger to trace the problem\u2014highly technical tools that require a professional to operate correctly.<\/li>\n<\/ul>\n<p>If the problem is caused by a faulty appliance, do not attempt to just repair the wire\u2014replace the appliance. Do not ever cut off the grounding prong from an appliance as a means of fixing a GFCI problem, as this will remove your margin of safety.<\/p>\n<h2>How to Prevent Ground Faults<\/h2>\n<p>Install GFCIs in every wet or outdoor area \u2014 this simple step is the best protection you&#8217;ll ever get.<\/p>\n<ul>\n<li>Keep water away from electricity: Don&#8217;t use machines by the sinks or bathtubs; don&#8217;t allow wires to lie on wet floors; and use only appropriate outdoor receptacles and covers outdoors.<\/li>\n<li>Check regularly the cords: Replace the wires as soon as you notice cracks or they have been bitten by pets.<\/li>\n<li>Avoid overloading the circuits: Overheating causes damaging of insulation and other faults.<\/li>\n<li>Use the suitable devices for outdoor use: weatherproof equipment, GFCI-protected outdoor outlets, portable GFCI for tools.<\/li>\n<li>Secure wiring from the pests and any physical damage: seal all holes rodents might enter from, and do not run wires through rugs and door openings.<\/li>\n<li>Test GFCIs each month: press TEST &#8211; it should trip; press RESET &#8211; it should restore.<\/li>\n<\/ul>\n<h2>\u0427\u0430\u0441\u0442\u043e \u0437\u0430\u0434\u0430\u0432\u0430\u0435\u043c\u044b\u0435 \u0432\u043e\u043f\u0440\u043e\u0441\u044b<\/h2>\n<h3>How do you fix a ground fault?<\/h3>\n<p>The first thing to do is confirm that everything on the circuit is unplugged, and then try resetting the ground fault circuit interrupter (GFCI) or circuit breaker. If the circuit is still live, plug in the appliances one at a time \u2014 when it trips, you will know which appliance is causing the problem. If even with everything unplugged the circuit trips, the problem lies in the fixed wiring: turn off power supply to the circuit, open the switches and\/or outlet boxes, and check for faulty connections or any wires that are allowing electricity to touch any other wire or metal box. Fix the issue and test the circuit. If problems persist, call an electrician.<\/p>\n<h3>What is a ground fault in simple terms?<\/h3>\n<p>To put it simply, a ground fault is when electricity goes off course and ends up in the ground. Normally, the flow of electricity goes from the power line to the neutral line. A ground fault occurs when the electricity finds another way to the ground through a broken wire touching a metal device, through water, or through a person. This is dangerous because a person can conduct the electricity. A GFCI device detects such leak at a very low level of 4 to 6 milliamperes and cuts off the current immediately before a serious shock happens.<\/p>\n<h3>How do you know if you have a ground fault?<\/h3>\n<p>The indications of a ground fault are as follows: a GFCI socket does trip time and again or cannot be reset; a circuit breaker is activated without visible cause; an appliance causes you to feel a tingling or minor shock; humming or crackling can be heard from an outlet; an offensive odor is detected; or the surface of an appliance makes you feel uncomfortable. If your appliance has GFIC protection, it will be the first indicator.<\/p>\n<h3>What causes a ground fault?<\/h3>\n<p>The reasons that this occurs most often are: wire insulation that has broken or been damaged (for example, cracked, worn, or eaten by rodents), water touching live wires and grounding them (for instance, in bathrooms, kitchens, open air), wrong wiring in appliances and metal bodies touching their wires, loose or incorrect connections, or damaged wiring or plugs. In other words: any situation in which live wires may come into contact with the ground.<\/p>\n<h2>\u0421\u0441\u044b\u043b\u043a\u0438<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.nfpa.org\/codes-and-standards\/all-codes-and-standards\/list-of-codes-and-standards\/detail?code=70\" rel=\"nofollow noopener\" target=\"_blank\">NFPA 70 \u2014 National Electrical Code (NEC), Article 210.8: GFCI requirements<\/a><\/li>\n<li><a href=\"https:\/\/www.ul.com\" rel=\"nofollow noopener\" target=\"_blank\">UL 943 \u2014 Standard for Ground-Fault Circuit-Interrupters<\/a><\/li>\n<li><a href=\"https:\/\/www.osha.gov\" rel=\"nofollow noopener\" target=\"_blank\">OSHA \u2014 electrical safety and ground fault protection requirements (29 CFR 1926.404)<\/a><\/li>\n<li><a href=\"https:\/\/www.cpsc.gov\" rel=\"nofollow noopener\" target=\"_blank\">U.S. Consumer Product Safety Commission \u2014 electrical safety guidance<\/a><\/li>\n<li><a href=\"https:\/\/www.esfi.org\" rel=\"nofollow noopener\" target=\"_blank\">Electrical Safety Foundation International \u2014 GFCI and ground fault safety resources<\/a><\/li>\n<li><a href=\"https:\/\/www.siemens.com\" rel=\"nofollow noopener\" target=\"_blank\">Siemens \u2014 ground fault protection technical documentation<\/a><\/li>\n<\/ul>\n<h2>\u0417\u0430\u043a\u043b\u044e\u0447\u0435\u043d\u0438\u0435<\/h2>\n<p>Ground fault is an undesirable current flow from a live wire to the ground and is one of the most serious electrical problems.
