What is GFCI?

You always hear about the term GFCI when it comes to electricity, but what does this mean? GFCI is a ground fault circuit interrupter, and it’s an electrical device that was designed to help protect your electrical system against a multitude of shocks.,

There are many reasons why you should install a GFCI unit. The primary concern and what makes you acquire such a tool is that it allows you to minimize the risks of any electrical burns and at the same time it also prevents shock injuries, not to mention that it can also prevent electrocutions.

The GFCI is designed to include ground fault protection in the receptacles most of the time in case it has to be near water or if it will be in contact with water. The GFCI unit will also help you detect any ground faults and interruptions that appear from the electric current. Keep in mind that you will not be able to use a GFCI to replace a fuse. This may not protect against shocks, short circuits or overloads.

If you are wondering how it works, the entire system is rather simple to understand. The electrical outlet has around 2 vertical slots, and it will have a round hole under them, right on the sides. You have the left slot trigger there, and that one is larger when compared to the right one which is named Hot. The idea here is that whenever the outlet works in a proper manner, you will see that the GFCI will enter in action when the electricity flows as it should from hot to neutral. This unit will measure how much current is flowing here, and it will be able to detect variations! If major variations are detected, the GFCI unit will only cut off the energy as fast as possible to offer the right protection immediately!

Where can you install a GFCI? It depends, most of the time these units are suitable for just about every home and institutions. The National Electrical Code states that the GFCI needs to be installed in healthcare facilities, during fairs and any outdoor activities, in laundry receptacles, garages, escalators, elevators, underwater pool lighting systems, garages, kitchens, unfinished basements, utility sinks, wet bars and so on.

You can find multiple types of GFCI units. With the common one being the GFCI receptacle which is pretty similar to the regular wall receptacle. You also have a portable GFCI, and this can easily be plugged into the traditional outlet. This will be able to offer the necessary protection at all times!

There are times when a GFCI might trip, but that doesn’t mean your installation has any problems. The idea is to keep the GFCI in a circuit which is less than 100 feet. Otherwise, interruptions will appear because of that. Before you install such a unit, you have to remember that loss of power can appear at times. This is why you have to keep that in mind, especially if you have a freezer, garage door opener and so on.
