A ground fault circuit interrupter is an electrical device installed to protect against severe electric shocks.
Gfi electrical meaning.
A gfci not to be confused with an afci integrates a ground fault protection in receptacles where electrical equipment is near water or might.
For example you may want to connect your electric lawn trimmer to a gfi outlet but your garage does not.
Because of this we need to understand what a gfci is how it works and what its limitations are we need only to look to the nec for the definition of a gfci.
A gfi or gfci ground fault circuit interrupter device protects us from receiving electric shocks from faults in the electrical devices we use in our home.
A ground fault is an instance in which the hot wire touches any area of a grounded device or even the grounded part of a junction box.
It is also possible to.
It works by comparing the input current on the hot side to the output current on the neutral side.
It will also trip when a short circuit or an electrical overload occurs.
Portable gfcis are used when there is no gfi installed nearby.
In short you were part of what s called a ground fault.
If the gfci trips it usually means a ground fault is caused by water a faulty appliance or broken insulation on the electrical wiring.
The main purpose is to protect people from an electric shock caused when some of the current travels through a person s body due to an electrical fault such as a short circuit insulation.
A gfci outlet may be wired in a branch circuit which means other outlets and electrical devices may share the same circuit and breaker or fuse.
When a properly wired gfci trips the other devices down the line from it will also lose power.
If you ve ever experienced even a second of paralysis caused by electrical shock it s not a feeling you ll ever forget.
A ground fault circuit interrupter gfci or residual current device rcd is a type of circuit breaker which shuts off electric power when it senses an imbalance between the outgoing and incoming current.
The gfci circuit breaker will shut off electricity in the event of a problem.
However any gfci protector has a limited lifespan.
Gfci s could also reduce electrocutions and minimize electrical burns and shock injuries.
