What is a GFCI?
A GFCI (Ground Fault Circuit Interrupter) is an automatic device that offers personal protection against lethal electrical shock or electrocution. It is a special electrical receptacle or outlet that can stop electrical power within milliseconds as a safety precaution. Let’s see how?
How does a GFCI work?
The GFCI works by measuring the current leaving the hot side of the power source and comparing it to the current returning to the neutral side. If they are not equal, this means that some of the current is flowing along an unintended path possibly through water or through a person.
What is the slot in a GFCI?
The larger “left slot” corresponds to “neutral and “right slot” is called “hot”. The third, round hole is the “ground”. Normally, electricity flows from hot to neutral in the outlet. The GFCI works by measuring the current leaving the hot side of the power source and comparing it to the current returning to the neutral side.
How many lives have been saved by GFCIs?
Thousands of lives saved: Since the 1970s, GFCIs have saved thousands of lives and have helped cut the number of home electrocutions in half. If GFCIs were installed in older homes, experts suggest 70 per cent of the electrocutions that occur each year in the home could be prevented.
When a person's body starts to receive a shock, the GFCI senses this and cuts off
So when a person’s body starts to receive a shock, the GFCI senses this and cuts off the power before he or she can get injured. In general, GFCIs are installed wherever there is the potential for contact between a person and an electrical appliance in or near moisture, water, or water pipes.
Where should GFCIs be installed?

What is ground fault?
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 injuries or death. The ground-fault circuit interrupter, or GFCI, is a fast-acting circuit breaker designed to shut ...
Does GFCI protect against ground fault?
The GFCI will not protect you from line contact hazards (i.e. a person holding two "hot" wires, a hot and a neutral wire in each hand, or contacting an overhead power line). However, it protects against the most common form of electrical shock hazard, the ground-fault. It also protects against fires, overheating, and destruction of wire insulation.
Can a GFCI trip?
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.
How many types of GFCI are there?
There are three types of GFCIs. The most often used “receptacle-type” GFCI, similar to a common wall outlet, is the type with which most consumers are familiar.
What is a GFCI?
A ground fault circuit interrupter (GFCI) can help prevent electrocution. If a person’s body starts to receive a shock, the GFCI senses this and cuts off the power before he/she can get injured. GFCIs are generally installed where electrical circuits may accidentally come into contact with water.
How often should a GFCI be checked?
GFCIs should be checked monthly to determine if they are operating properly. A portable GFCI should be used out-of-doors with various electrical power tools (i.e., drills, mowers, trimmers) and should be tested before each use!
How does a GFCI sense a circuit?
The GFCI will “sense” the difference in the amount of electricity flowing into the circuit to that flowing out, even in amounts of current as small as 4 or 5 milliamps. The GFCI reacts quickly (less than one-tenth of a second) to trip or shut off the circuit.
Why is GFCI protection used?
Because of this potential for shock, GFCI protection is used to protect human life.
What is a ground fault?
According to the National Electrical Code, a “ground fault” is a conducting connection (whether intentional or accidental) between any electric conductor and any conducting material that is grounded or that may become grounded. Electricity always wants to find a path to the ground. In a ground fault, electricity has found a path to ground, ...
