Perhaps you might have been in a house or an establishment wherein the outlets have three slots: two vertical slots and one hole below in the center. Perhaps you might be wondering why the left vertical slot is slightly bigger than the right vertical slot or why is there a hole on the outlet. Outlets like that are called GFC outlets or Ground Fault Circuit outlets. The left vertical slot is what they call “neutral,” the right slot “hot”, and the hole is the “ground.”
Our reliable experts with years of experience are here to help you with your electrical needs and projects.
Technically, if your electrical device is in good condition, the electricity from the outlet to your device will only flow from hot to neutral. Your Cambridge, MA GFC outlet is connected to a circuit interrupter. The ground circuit can sense if there is a change in the amount of electricity that flows through the hot and neutral slots. After sensing it, it will activate the interrupter and will cut the flow of electricity, protecting you or any of your family members from possible electrocution. GFC outlets in Cambridge, MA can save lives. If you do not have them in your home yet, contact a professional, and they will upgrade all your existing outlets to GFC Outlets. Installing the ground circuitry of GFC outlets in Cambridge, MA is not a DIY job. They will be useless if improperly installed.
