Your bathroom must have a GFI outlet. Most new homes or newly remodeled homes require you to have GFI electrical outlets in the kitchen. Most older kitchens don’t have GFI electrical outlets. GFI stands for Ground Fault Circuit Interrupter.
Why not call it GFCI instead of GFI outlet? Well, in some cases it is called GFCI. GFI is short and is the most common name used by most electricians and builders for this type of outlet.
GFIs come in 15 and 20 amp outlets. GFI outlets must be connected properly. Make sure to use the correct size cable when connecting the GFI outlet.
How do I know what size cable to use? This all depends on how far you are running it from the electrical panel. There are charts that you can use to solve this. If you are not running the power cord more than 80 feet from the electrical panel, you can use 12 gauge electrical cords for a 20 amp GFI. This is a general rule of thumb for most household electrical cords.
If you are going to use a 15 amp GFI and it is going to be less than 80 feet away from the electrical panel, you can use 14 gauge electrical cords. Again, this is just a general rule of thumb for most household electrical cords.
A GFI is a light-duty electrical outlet that is used in bathrooms, kitchens, and the outside of your home. The sole purpose of the GFI is to turn off the breaker faster if there is any moisture or light load problem.
Say, for example, you have your hair dryer plugged into the GFI socket. The hair dryer somehow falls into the sink while it’s on or plugged in. The GFI outlet will turn off instantly due to the sensitivity of the circuit breaker inside the plug.
The GFI socket has a test button and a reset button. If you are continually rebooting the GFI it will eventually wear it out. I’ve had GFI plugs after resetting the button about 10 times and can’t use them anymore.
The GFI electrical outlet is a great idea and if you don’t have them in your bathroom or outside your home, it would be a great idea to have an electrician install them for you.
