Your GFCI, or "ground fault circuit interrupter" outlets are a shockingly overlooked safety mechanism of your home's electrical system. They're installed in high-moisture areas of your home like kitchens, bathrooms, exteriors and elsewhere to prevent electrocution. These safety features cut power to an outlet when they sense an interruption of the electrical current, specifically when electricity passes through water. Your GFCIs can fail without warning, so it's important for homeowners to know how to test them, and to do so periodically to avoid getting zapped. Lauren shows you the step-by-step of this eminently easy DIY... #gfci #electrical #electricity #homeowner #fyp
