What is the name of the device that interrupts the current when there is a problem with an electrical ground?

The device that interrupts the current when there is a problem with an electrical ground is known as a Ground Fault Interrupter (GFI). This device is designed to protect people from electric shock by detecting imbalances in the electric current. When the GFI senses that electrical current is leaking, which typically happens when there's an unintended path to the ground (for example, if a person touches a live wire), it quickly cuts off the power to prevent injury.

GFIs are especially important in locations where moisture is prevalent, such as bathrooms, kitchens, and outdoor outlets, because the risk of electric shock increases in these environments. The primary function of a GFI is to ensure safety by preventing potential electrocution, highlighting the importance of grounding in electrical systems.

In contrast, the other options listed do not refer specifically to devices with the same purpose. Therefore, a GFI is the essential device recognized for ensuring safe electrical grounding and preventing electrical accidents.
