To be called a GFCI (Ground Fault Circuit Interruptor) the unit needs to trip no higher than 6mA.  Above that the unit becomes an ELCI (Equipment Leakage Circuit Interruptor).

A Ground-fault occurs when there is a break in the low resistance grounding path from a tool or electrical system. The electrical current may then take an alternative path to the ground through the user, resulting in serious injury or death.  The ground-fault circuit interrupter, or GFCI, is a fas acting circuit breaker designed to shut of electric power in the event of a ground fault within as little as 1/40 of a second. It works by comparing the amount of current going to and returning from the equipment along the circuit conductors. When the amount going differs from the amour retuning by approximately 5 milliamperes (4-6mA), the GFCI trips/interrupts the current.

The GFCI is rated to trip quickly enough to prevent an electrical incident.  If it is properly installed and maintained, this will happen as soon as the faulty tool is plugged in.  If the grounding conductor is not intact or of low impedance the GFCI may not trip until a person provides a path.  In this case, the person will receive a shock, but the GFCI should trip so quickly that the shock will not be harmful. The most common type of shock is from the Ground Fault. GFCIs also protect against fires, overheating and wire destruction.

Una pérdida a tierra ocurre cuando hay una ruptura en el camino de resistencia baja para conexión a tierra de una herramienta o un sistema eléctrico. La corriente eléctrica entonces puede tomar una trayectoria alterna a la tierra a través del trabajador, resultando en lesiones serias o la muerte.
El interruptor para circuitos con pérdida a tierra, o GFCI, es un circuito interruptor de energía de acción rápida diseñado para desconectar la energía eléctrica en caso de una pérdida a tierra en un lapso de 140 de segundo. Esto funciona comparando la cantidad de corriente que sale y que regresa del equipo a lo largo de los conductores de circuito. Cuando la cantidad que sale es diferente de la cantidad que regresa por aproximadamente 5 mili-amperios, el GFCI interrumpe la corriente.
El GFCI está clasificado para desconectar la corriente suficientemente rápido para prevenir un incidente eléctrico. Si es instalado y mantenido correctamente, esto pasará tan pronto como el equipo defectuoso es enchufado. Si el conductor de conexión a tierra no está intacto o es de baja impedancia, el GFCI quizás no funcione hasta que una persona le proporcione una trayectoria. En este caso, la persona recibirá una descarga, pero el GFCI debe activarse tan rápidamente que la descarga no sería mortal o dañina.

OSHA Rule Expands Requirements for GFCI Use


OSHA Rule Expands Requirements for GFCI Use
Buy at Sords Electric


Are you compliant?
An important change in OSHA Regulations in 2007 has broadened
the requirements for using portable GFCI’s inmost industries.



OverviewMandatory use of portable Ground Fault Circuit Interrupters (GFCI’s) began in the 1970’s not long after the Occupational Safety and Health Administration (OSHA) was formed by an Act of
Congress. The first requirements for GFCI use resulted from an OSHA mandate applying to
Construction Industry businesses. The mandate required the use of GFCI’s whenever
“temporary power”was used on the jobsite. The resulting use of GFCI’s in construction work has saved many workers’lives in the intervening years since the mandate was issued.
Capitalizing on the Construction Industry safety benefits realized, new regulations which went into effect in August, 2007 extended GFCI-use requirements for the first time to OSHA’s General Industry category of businesses which cover most of the rest of U.S. industry with the exception of agriculture, mining and maritime. Now, in order to comply with OSHA Regulations, a great deal of maintenance, remodeling or repair activities, involving buildings, structures or equipment must be done with workers using GFCI protected equipment.
The new activities for which OSHA has mandated the use of GFCI’s cover a large segment of industrial functions having“construction-like” characteristics such as are found in MRO, facilities engineering and disaster preparedness and recovery disciplines. Industries covered include
product and materials manufacturing, automotive manufacturing, breweries and bottling plants, chemical and petrochemical processing, food processing and many others.
Previously, most portable GFCI extension cords, quad boxes and other ground fault
protection equipment have been bought by construction and electrical contractors.
Distributors will now find many new opportunities for GFCI sales with their industrial customers.

BACKGROUND

OSHA’s scope of regulation covers three major business areas; the Construction Industry, the Maritime Industry and a third category, General Industry, which covers most other business enterprises except for those in mining and agriculture which are overseen by other government
agencies. OSHA’s regulations are Federal Law and are contained in the U.S. Government’s Code of Federal Regulations (CFR). Violations of OSHA regulations can subject companies to legal action and fines.
Prior to the most recent update, OSHA's General Industry electrical regulations (29CFR1910, Subpart S) were last updated in August 1990 and were based on Part I of the National Fire Protection Association’s NFPA 70E Standard entitled Electrical Safety Requirements for EmployeeWorkplaces (1988 Edition). OSHA’s Construction Industry electrical regulations (29CFR1926, Subpart K) were last updated in 1986. NFPA 70E provides practical application to
OSHA requirements. Numerous enhancements in technology have occurred since these regulations were last revised.
In an effort to bring its regulations up to date, OSHA published new General Industry regulations in 2007 based on Part I of the 2000 Edition of NFPA 70E. In doing so, and in response to requests from industry stakeholders, OSHA has provided General Industry companies with new rules that reflect more current versions of NFPA 70E and the National
Electrical Code (NEC). In fact, until they are updated in the future, the General Industry rules regarding GFCIs are now more up-to-date than those for the Construction Industry.


Regulations


Set forth below are the actual citations from OSHA’s General Industry regulations that were issued in 2007. Keep in mind that prior to the issuance of these new regulations, OSHA did not require the use of GFCIs for construction-like work performed by General Industry companies.


From29CFR1910, Subpart S, Article 1910.304(b)(3)
Ground-fault circuit interrupter protection for personnel.

1910.304(b)(3)(i)
All 125 Volt, single-phase, 15 and 20 Ampere receptacles installed in bathrooms or on rooftops shall have ground fault circuit interrupter protection for personnel.

1910.304(b)(3)(ii)
The following requirements apply to temporary wiring installations that are used during construction-like activities, including certain maintenance, remodeling, or repair activities involving buildings, structures or equipment.

1910.304(b)(3)(ii)(A)
All 125 Volt, single-phase, 15, 20, and 30 Ampere receptacle outlets that are not part of the permanent wiring of the building or structure and that are in use by personnel shall have ground fault circuit interrupter protection for personnel.
Note 1 to paragraph (b)(3)(ii)(A) of this section: A cord connector on an extension cord set is considered to be a receptacle outlet if the cord set is used for temporary electric power.
Note 2 to paragraph (b)(3)(ii)(A) of this section: Cord sets and devices incorporating the required ground fault circuit interrupter that are connected to the receptacle closest to the source of power are acceptable forms of protection.

1910.304(b)(3)(ii)(B)
Receptacles other than 125 Volt, single-phase, 15, 20, and 30 Ampere receptacles that are not part of the permanent wiring of the building or structure and that are in use by personnel shall have ground fault circuit interrupter protection for personnel.  (Extension cords with Ground Fault built in.)

1910.304(b)(3)(ii)(C)
Where the ground fault circuit interrupter protection required by paragraph (b)(3)(ii)(B) of this section is not available for receptacles other than 125 Volt, single-phase, 15, 20, and 30 Ampere, the employer shall establish and implement an assured equipment grounding conductor program covering cord sets, receptacles that are not a part of the building or structure, and equipment connected by cord and plug that are available for use or used by employees on those receptacles.

GFCI ~ manual reset vs. automatic reset

trc gfci 30 amp
Ground Fault Circuit Interrupter or a GFCI is a switch designed to protect people from electrical shocks and electrocution.  The GFCI monitors the current flow into and out of an appliance or circuit and if the current is not equal, the GFCI will switch or trip in milliseconds.  After a trip the GFCI needs to be reset by pushing the "reset" button on the GFCI.  GFIC's are  required in homes in the bathrooms, kitchens and laundry rooms.  

A GFCI can come in wither manual reset mode or automatic reset models.  In this discussion regarding auto vs. manual reset is not after a GFCI trips due to a fault, but when the GFCI's circuit loses power or is initially powered up or plugged in.  GFCI's in homes that are wired into the wall are all AUTO reset GFCI's.  The GFCI after a power outage will reset itself with an electrical coil so that it is "ready" to go.  An auto reset GFCI should always be used for indoor use when the load is not a dangerous.  

A manual reset GFCI is usually used for outdoor power equipment or on the job site electrical tools and applications.The manual reset GFCI will need to be "reset" when the GFCI is plugged in or when power is applied to the curcuit.  The GFCI will trip when power is removed from the circuit or unplugged.  The GFCI will also trip when a fault is detected.  In both cases the GFCI will need to be manually reset.  Most of the GFCI's that we sell are manual reset GFCI's.

GFCI ~ Ground Fault Circuit Interrupter

A "GFCI" is a ground fault circuit interrupter. A ground fault circuit interrupter is an inexpensive electrical device that, if installed in household branch circuits, could prevent over two-thirds of the approximately 300 electrocutions still occurring each year in and around the home. Installation of the device could also prevent thousands of burn and electric shock injuries each year.

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 or other building's wiring system, 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 small amount from that returning, the GFCI quickly switches off power to that circuit. 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.

In homes built to comply with the National Electrical Code (the Code), GFCI protection is required for most outdoor receptacles (since 1973), bathroom receptacle circuits (since 1975), garage wall outlets (since 1978), kitchen receptacles (since 1987), and all receptacles in crawl spaces and unfinished basements (since 1990).

Owners of homes that do not have GFCls installed in all those critical areas specified in the latest version of the Code should consider having them installed. For broad protection, GFCI circuit breakers may be added in many panels of older homes to replace ordinary circuit breaker. For homes protected by fuses, you are limited to receptacle or portable-type GFCIs and these may be installed in areas of greatest exposure, such as the bathroom, kitchen, basement, garage, and outdoor circuits.

A GFCI should be used whenever operating electrically powered garden equipment (mower, hedge trimmer, edger, etc.). Consumers can obtain similar protection by using GFCIs with electric tools (drills, saws, sanders, etc.) for do-it-yourself work in and around the house.

Circuit breaker and receptacle-type GFCIs may be installed in your home by a qualified electrician. Receptacle-type GFCIs may be installed by knowledgeable consumers familiar with electrical wiring practices who also follow the instructions accompanying the device. When in doubt about the proper procedure, contact a qualified electrician. Do not attempt to install it yourself.

The portable GFCI requires no special knowledge or equipment to install.

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 GFCI 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.

GFCI's should be used in Commercial and industrial enviroments as well.  NEC code requires the use of GFCI's with all portable electrical tools, that need to be plugged in, within a plant or on a job site.
