Protect outlets in wet locations by installing ground-fault circuit interrupters.
For this, the electrical outlet into which the tool is plugged has to be protected by a device called a ground-fault circuit interrupter.
There may be locations, however, where there are no circuit interrupters within reach.
He also invented the ground-fault circuit interrupter or GFCI, based on his understanding of electric shock in humans.
Based upon a dry arc test method used for testing wire insulation material, this test was originally developed for arc-fault circuit interrupters.
Another safety device introduced with the 1999 code is the arc-fault circuit interrupter (AFCI).
The device is called a ground-fault circuit interrupter.
Built-in circuit interrupters can be connected in many different ways, but unless you are experienced in electrical work, leave the more complicated methods to a licensed electrician.
Here is how to install a ground-fault circuit interrupter in place of an outlet with two slots and a hole.
This is the entire reason ground-fault circuit interrupters exist.
