What If I Move Into a Home Without Grounded Outlets? However, using a grounded plug and outlet, the electricity flows from the wire into the ground, every time, which trips the breaker in the break box, stopping the circuit and preventing electrical accidents. However, if you were to plug a metal appliance into a two-pronged outlet, and a hot wire comes loose inside that ungrounded metal appliance, the metal casing would instantly become hot, delivering a fatal electrical shock.
The appliances you choose to plug into the outlet completes this circuit, allowing electricity to flow through your appliance to heat coils, run a motor, etc. How is this accomplished? Because electricity always flows in a circuit, power in an outlet flows from hot to neutral. Grounding through use of these types of outlets is intended to protect individuals who use metal-encased appliances from severe electrical shock. Two vertical slots, the left called “neutral” and the right called “hot,” and a hole at the base called “ground.” New plugs are engineered to fit into these upgraded outlets. New, standardized 120-volt outlets in the US have three holes. Two-pronged outlets are referred to as “ungrounded,” while three-pronged are grounded.
You may be wondering what all the change is about why haven’t manufacturers stuck to the “old,” two-pronged format and made life easier for everyone? If you currently live or have lived in a home with outlets that accept only two-pronged plugs, you may have had to purchase an adaptor to use some of your more modern appliances that feature three-pronged plugs.
