If you plug a dryer into a grounded outlet, it should work properly and safely. In fact, it is highly recommended to connect appliances like dryers to grounded outlets for safety reasons.
A grounded outlet has a third prong, which is the grounding pin. This pin is connected to the ground wire in the electrical system of your home. The purpose of grounding is to provide a path of least resistance for electrical faults or surges, diverting them safely into the ground instead of through you or the appliance.
When you plug a dryer into a grounded outlet, it allows the appliance to connect to the electrical system's ground, reducing the risk of electric shock and preventing potential damage to the dryer and other electrical components. The grounding pin ensures that any excess electrical current is directed away from the dryer and into the ground.
In summary, using a grounded outlet for your dryer is the safe and recommended way to connect it. It helps protect against electrical hazards and ensures the proper functioning of the appliance.
