83.6 million sleep deprived people are shuffling around the U.S. at any given moment – so it makes sense that businesses are investing in products and technologies that focus on ways to get a good night’s rest.

When recent update to iOS 9.3 introduced Night Shift, a feature that takes its cues from the sun (or more specifically, your device’s clock and geolocation) to gently shift the color temperature of your display to the warmer end of the light spectrum at night which may help you get a better night’s sleep.

Electrical safety is of utmost importance to keep your family and loved ones safe at home. You can be assured of electrical safety through GFCI outlets. GFCI (ground fault circuit interrupter) outlets have three holes: two of the holes are for neutral and hot wire and the third hole in the middle of the outlet serves as a ground wire. If it experiences any change in the electrical flow in the circuit, it will immediately cut off the flow of electricity.

GFCI outlets are important, especially when the electrical outlets are positioned close to water. Installing GFCI outlets in your kitchen, bathrooms, laundry rooms, etc., is a good idea. Apart from being an essential preventive measure, the law also requires you to have GFCI outlets installed throughout your home. According to National Electric Code (NEC), all homes must be equipped with GFCI protection. Initially, it was only required for you to install GFCI outlets near water only but this requirement has been extended to cover all single phase outlets of 125 volts in recent years.

Let us now understand why GFCI outlets are essential in every household.

3 Reasons to Install GFCI Outlets

Electrical shocks and electrocution are the major risks that you can be exposed to through electrical devices at your home. This becomes a bigger concern if you have kids who can unknowingly touch the appliances and get a shock. A GFCI outlet helps in preventing shocks and electrocutions as it has a built-in sensor that monitors the inflow and outflow of the electricity from any appliance. If a live wire inside the appliance comes in contact with the metallic surface of the appliance, you will get a shock when you touch it.

In general, you don’t want anything in your home’s electrical system to create sparks. It’s usually a major warning sign that the system requires repairs. You should immediately stop using the sparking appliance and call for professional electricians.

However, sparks from outlets are something that homeowners often ignore. Its commonplace for a slight blue spark to appear when you plug an electrical appliance, like a vacuum cleaner or a toaster into a wall outlet: this is a visible effect from the start of the flow of electrons. However, larger sparks might begin to occur. When this happens, you need to call for professional electrical repairs as soon as possible. Under no circumstances should you attempt to open up the outlet cover and investigate the sparking on your own—this is potentially very hazardous.

There are a number of possible causes for an outlet to develop the dangerous sparking that might lead to electrical fires. One of the common reasons is that the outlet has overheated and melted the insulation around the wires. (This is why you should never use an octopus plug to connect too many appliances into a single outlet at the same time; it’s easy for the outlet to overheat.) When the wires are exposed because of melted insulation, it can cause electrons to leap from the wire to the metal case or even the opposite wire. This is known as a short circuit. Short circuits are potentially very dangerous as sources of electrical fires. Most of the time, a short will cause the circuit breaker panel to trip and cut off the circuit to prevent further damage. Frequently tripped breakers are a major warning sign that your have trouble with an outlet.

However, if there are other problems with the wiring your home, a short circuit in an outlet could start a fire behind the walls. If you ignore major sparking from an outlet, this is one of the risks that you’ll take.

Fortunately, professional electricians are experienced with fixing and replacing faulty outlets to prevent the dangers of short circuits. You should watch out not only for sparking from outlets, but also outlets that feel hot to the touch or show signs of discoloration and charring on their surface. An outlet that continually trips circuit breakers also needs an electrician to investigate it.
